Choosing a Network Connection Solution in Various Conditions to Access Online Gambling Poker

Building an efficient network infrastructure is certainly a necessity so that the performance of your system becomes the most reliable in handing service access to authorized users for all existing network resources. Especially in gaming business, sophisticated Memory and VGA is a must to provide the best experience such as graphic and minimum lagging. Not just for game like Fps or MMORPG, but board game or casino game like in the https://judisakti.org now also require such requirement to play their graphic.

LAN Design

It is better to clean up and design LAN network infrastructure first as efficiently as possible before creating a network connection to Cloud WAN that connects all remote sites into your corporate network. This does not mean you do not need to create a WAN design into your network design until the entire local network location of your network is formed, but you concentrate first until you can ensure that your LAN network connection system is efficient before creating a connection to the WAN.

There will be very few activities that will be completed in this network connection and depending on how large your network design scale is. Make a network connection in a company where the office consists of a number of remote sites even up to the geography boundary, in contrast to a network connection in a local location network that connects a number of buildings in a company area or maybe just in a small office room. You must have completed your network design including computer systems that will use this network infrastructure system. This network connection work is complicated depending on how large your network is, especially if you have to design a backup in case network, a disaster occurs or anticipate problems in the network.

LAN scenario

It is assumed that you have created your network design and some of your site diagrams like the picture below, how do you make a network connection according to this site diagram?

The server room where a number of your servers are located in the HRD building. there are 80 users in this building. I say a number of servers – why aren’t all servers in one room and in the same building? This concerns the security of security best practice standards regarding placement servers (next article). There are still two more buildings that must be connected in a network connection:

  1. Mining building which is 70 meters away from the HRD building (there are also 80 users)
  2. Shop that is under a valley that is more than 300 meters from the HRD building (there are 50 users here)

Adjust to the total user

The total users in this network are 200 (80 in the HRD + 80 building in Mining + 40 in the Workshop), and do not include the need for a permanent IP address for a number of servers; printer; Wireless Access Point; switch; and even VoIP. You can use a private IP network say 192.168.100.0/24 (254 IP addres available) for all users and devices in this network. For that you can use 4 24-port switches on the cascade in both mining buildings and HRDs with the standard 100BaseT Ethernet. While in the workshop there were quite a few switches 24 ports on the cascade. With the exception of the server room you need a Gigabit 12 port switch if all your servers are equipped with Gigabit Ethernet, for the fastest data transfer and it will be very useful if you use a single Autoloader backup device to backup all data servers; exchange and your database, which is routinely carried out at night.

Network Connection

Then how about the network connection between the HRD building and the Workshop? Because the location of this Workshop is under a valley with a distance of more than 300 meters, it is impossible for you to use a cable connection. Then you can use Wireless technology that connects two or more points of the access point via radio frequencies 2.4 GigaHz. You can get this kind of product on the Cisco Aironet sample market. You can build two simple towers to place the antenna at the top of the tower from the two access point antennas can watch each other without obstruction. This Wireless Device can transmit data up to 58 Mbps; not bad for the link between these buildings using air transmission media. Please read the next article about wireless local location network.

Now how do you connect the network connection between buildings in Mining and at HRD that is 70 meters away? This will depend on the challenges you face, if you have to conclude for a unique underground cable then use the UTP Cat 6 outdoor LAN cable which is exclusively designed for outdoor use and water resistance and gigabit support speed. However, for security arguments and maintenance facilities, enter this UTP cable with a fairly large diameter into an iron pipe or the like and if you need to make special drainage such as water drainage.

Wifi connection?

Why not just use wireless networks between these two buildings like between HRDs and workshops? Indeed, with the most practical wireless network, you don’t need to bother 2 underground cables, but you know that wireless speeds up to 450 Mbps are currently very high (802.11n standards with three spatial data streams) in theory. – You will not be able to achieve this speed), while between the two buildings you need a reliable connection with gigabit speed as a two-building backbone in redundancy (with STP enabled).

Even in the Mining office there are a number of data servers and mining software, the largest of which are data, especially geological data and must be backed up centrally in the HRD building. Not to mention the challenge of blackspot if there is a problem with your wireless, or the number of obstacles to radio frequency interference. While the use of the workshop building is a problem requiring us to use a wireless radio network because the building must go through the valley and not allow unique cables through the forest, even though it is only 300 meters away, and there is no critical system that must be given. The most reliable wireless network if both tower antennas can watch each other (LOS – line of sight). And again, the workshop only requires connections for computer clients.

Note: 5th generation wifi technology is available now with speeds of up to 1,300Mbps, 802.11ac. See Netgear R6300 Wifi 5g router.

To complete this network connection, you still need to think about network configuration and network setup for all devices in this network connection such as IP addresses to all PC clients; Permanent IP for server use; switch; printer and so on.

What’s next? What you need to consider is that documentation of all of these activities is classified as a disaster recovery plan – a backup plan – plan B from being a disaster. After the network connection problem is resolved and can be connected properly, the next step is to open Chrome and access the Online Poker site.

A variety of common network problems

Computer network problems can cause network software problems and disruptions to business continuity. The scale of this disturbance can vary depending on the source of the disturbance and the consequences it has on your infrastructure network. Network problems can cause downtime (how come the language …?) And this downtime can vary depending on how well you plan planning contingencies. Good management of your network system files can help you minimize downtime and make it easier for you to troubleshoot your network problems.

Various types of network problems

There are not a few types of network problems that can cause disruption to a computer, disruption of local networks, to disruptions to the global network of business connections in your corporate.

Network problems due to network cable failure

This is a common network problem that you encounter with the impact of network cable breakdowns that can affect the performance of a computer on the network because of the breakup of your patch cable because it was bitten by a mouse; dominant network problems in one building block because the cable breaks between switches (uplink cable); or even dominant in the majority of computers in your LAN network due to failure of backbone cable.

Impact of network collapse

The dominant network problem on a computer may not be a big problem except that of the general’s computer or your director. But the dominant network problems in your LAN network in bulk or even globally dominant in your corporate business can create a cold sweat. In a large-scale network infrastructure system, a redundancy system must be implemented. So that if a failure occurs in one network path it will not result in network failure in long periods.

Enable STP switch

In a residential multi switch network, the Spanning Tree Protocol (STP) must be enabled and tuned manually. STP is a service that allows the switch-2 network and bridge-2 of your LAN to be connected to each other in a redundant manner with a mechanism that can prevent bridging loops. The bridging loop is a data packet that is circling in the network looking for addresses to exhaustion and the end of koid. This bridging loop can cause your network traffic to crash or be called broadcast storm.

Network problems due to network device failure

The scale of the disruption of the impact of network device failures can also vary, from merely a computer because of the failure of the NIC – LAN card; number of computers due to switch failure; or even wide-scale causes of failure on central switches that connect server networks. For lan card failures between computers it can be replaced with your backup network card.

Link redundancy

So what if the network failure impacts damage to the switch? Your design regarding network redundancy will be very helpful in securing your network failure. The need for load balancing and redundancy must be assessed for every need according to the use of redundancy links; router device; switches and multi-homed hosts that have critical properties. The purpose of this redundancy system is to ensure the availability of services where there is no single point of failure.

Let’s look at the picture above regarding the system of redundancy.

Switch redundancy; If a problem occurs due to a failure on switch A, Switch B can still be useful for supplying links to the server and also to the two channel switches and links to the WAN. This type of network problem will not affect the server down system.

Router redundancy will create a WAN link backup when problems occur between routers. For example, between routers that connect your frame relay network to other offices, there are still backup links on the other router.

Link redundancy – will backup the link if there is a network problem with the link being disconnected to the server or to the switch.

We can apply this redundancy system to the previous scenario model that connects both the Mining and HR offices with unique two underground Cat5e UTP cables as redundancy links. Make sure that both of these redundancy cables are not connected to the same switch, because if there is a failure on the switch it will be useless.

For internet link redundancy, the router is actually already in the market a little with two or more WAN ports to the point that it doesn’t need two routers. This type of router is often for small medium offices where two WAN ports can failover – failback. So if the main link fails, it will failover to the backup link. Or you can also create two links load balancing, let’s say FVS336G Dual Wan Gigabit SSL VPN Firewall.

Network problems due to system failure

Although system failure is not the impact of network infrastructure failure, your users will still call you with the following questions: “Hello Agus … is there a network problem? I can’t access my email … or something like this “I can’t access the internet … or even a question from a radio operator” Hello Agus … how come I can’t access the folder President Director … why is that? ”

System failure can be caused by a problem with your DHCP server so that clients do not accept an IP address. Or it could be because there is a problem with your Directory Services system so that clients cannot log on to the network. Or it could be because there is a problem with registering names in your DNS system.

Network problems due to the spread of the virus

This type is also a network problem that is not due to physical network infrastructure failure, but your network system will be flooded with traffic from the influence of viruses that attack the system server and infect all computers in your network. The performance of your network system will be the slowest even to say collapsed. What you can do with this virus attack is to implement best practice security policy, your system defense must be very immune.

All kinds of network problems, you as a network and system administrator must be able to solve the problem. It doesn’t matter whether the problem is the failure of your network device; or your computer system problems; or an intruder that attacks your system infrastructure system. A good redundancy network design and a good management system is an obligation on a network scale that has a broad and complex nature.

Network Connection

What is SSL Secure Socket Layer

SSL is short for Secure Socket Layer which is a transport layer protocol that is used in a secure internet connection. If you want a communication connection via the internet with a secure technique, then use an SSL connection.

SSL offers three levels of security, namely:

  • Authentication: Ensures that the message received is from someone who is explicit
  • Confidentiality: Protects messages from a reading effort by recipients who are not eligible throughout their journey.
  • Integrity: Ensuring that the original message, does not feel a change in its journey.

The first two you can get from your ISP, contact your ISP to convince him.

SSL operates between the Application and Transport layers in the OSI model. SSL does not work transparently automatically, because only if the application protocols are explicitly implemented.

SSL uses public-key encryption for the purpose of authentication and symmetric key encryption to encrypt the information sent. For public SSL encryption keys, use the Rivest-Shamir-Adleman (RSA) encryption algorithm, so it depends on the implementation of the supported infrastructure public key (PKI). Message integrity is ensured by an integrity checking mechanism technique called a message authentication code (MAC).

Authentication process

An SSL session starts when an SSL-enabled client requests a connection with a server with SSL-enabled over TCP port 443, the SSL port. This will initiate an SSL connection between the client and server. All sites that use SSL have a URL with the HTTPS prefix. The server then sends the digital certificate and public key to the client.

The client server then negotiates which level of encryption can be received which is often 40-bit, 56-bit, or 128-bit and above. The client then generates a secret session key which is then encrypted using the public key from the server to send it to the server. The server then decodes the secret session key using the private key. From this point onwards, the secret key cryptography is imposed and then the session key is used to encrypt all data exchanges between the client and the server, leaving a secure private communication.

SSL is certainly not free from problems. All web transactions with SSL will increase processing overhead on the server. Sometimes it is double the process overhead compared to using a secure SSL connection. With the same machine hardware, the processing load level using SSL will be the heaviest compared to without SSL.

Besides that, SSL is difficult to implement in e-commuters that use web server farms and server load balancers. This view of SSL is designed so that the client uses the same IP address around the session.

To overcome this problem, often used exclusive hardware called SSL Accelerators to collect processing fees and cache sessions for different servers to increase performance.

Computers

Introduction of Types of Computer Networks

A network is a collection of desktop or laptop computers and other network devices such as printers that are connected together with the main destination is to communicate with each other and exchange data with each other. The core of computer networks is sharing and allowing your computer to connect to the internet, communicate with each other, and share resources like files and printers.

Network benefits

With the network, you will get a lot of flexibility in your work and provide time together with computers and electronic equipment. With a computer network you can:

  1. You can share one broadband internet connection to the point that everyone on your network can simultaneously surf – surf the internet – so it doesn’t take turns.
  2. You can access your email account while surfing and digging different data
  3. Can share all kinds of files like documents, belonging to music, digital images, and other documents.
  4. You can store your music, image, and file libraries into one place, a storage media, for example NAS (network access storage). That way you can access your music file from anywhere in your home via the network.
  5. Can save your computer against attacks from the internet such as viruses, worms, hackers etc. centrally. See also Pacth management
  6. You can watch one-on-one game games, or online multiplayer games with your family and even with your colleagues all over the world
  7. You can save money by simply buying one printer, storage media, or other equipment to be used simultaneously through the network. See also network sharing printers.

There are so many benefits with the network, you can share storage and access files on other computers through the network that is in your home or commonly called a LAN (local location network) network. It doesn’t matter where you save the file, you can always access it, of course with certain restrictions. And if you use share storage, you don’t need to have to turn on your computer so that other computers can access it. You can also save your files on different computers / storage on the Internet or commonly called WAN (wide location network).

Network Type

There are not a few types of networks according to the size and proximity. And almost everything can be categorized into two basic collections namely local location network (LAN) and wide location network (WAN).

Local Network

A LAN is a network of a set of computers, printers, or other network equipment that is connected to one another in different ways as in a home, office, or school and campus. This allows users who are connected to the network to share files, printers, or storage together. Whether this network consists of only two computers or in the largest scale, the main destination is so that each user can share information quickly and easily. So often a LAN is limited to a distance in one building or location that can communicate with each other quickly.

WAN network

While a WAN is a group of computer networks on a large scale across geographic boundaries, such as between cities or between countries. A simple example of a WAN network is the Internet where all computers in all worlds can be interrelated and communicate (of course with certain limitations). A router is needed to communicate with each other between your personal LAN network and the WAN network using a common network protocol called TCP / IP.

The picture above indicates a concept diagram of a network where a LAN network is connected to a WAN (internet) network using a router.

There are two main types of networks:

  1. Wired or wired network – Communication over a data cable – commonly using an Ethernet base
  2. wireless network – data communication passes through radio waves

It is most common for networks home or office to use a combination of both: cable and wireless.

Why choose a cable network?

Wired (cable) networks have been around for decades. Wired network technology that is now very popular is Ethernet networks. Data cables, commonly referred to as Ethernet network cables (CAT5), are used to connect computers and other network equipment that make up the network. A wired network is very good if you need a large amount of data transfer with the highest speed and reliable, just call it for gaming and entertainment media like HD (high definition) video.

The advantages of a wired network are the following:

  1. Actual cheap costs
  2. Offer the highest performance
  3. High speed – the standard speed of Ethernet cable is 100 Mbps
  4. Higher speed – Gigabit Ethernet cable up to 1000 Mbps

Why use wireless networks?

Wireless networks do not use cables to connect to each other. however they will use radio waves like your cellular telephone. The main advantage of wireless networking is that it is mobile (mobile) and free from a cable or fixed connection limitation. The advantages of wireless networks are the following:

  1. The nature is mobile and free – you can play from anywhere in the wireless network signal coverage
  2. Not limited to cable connections or fixed connections.
  3. Fast installation and not difficult, do not need to drill the wall to penetrate it for network cable needs
  4. No need to purchase a network data cable to the point that it saves times and is not complicated
  5. Easy to develop

With wireless networks you can use your computer anywhere in your home or office, even in the park or in your gazebo. You can check email and browsing or online or even you can print wirelessly from other rooms. we don’t need to drill holes to install Ethernet network cables to break down walls. You can connect to a wireless network. Outside the house you can connect with public hotspot networks such as cafes, airports, hotels, campuses etc. This is very suitable for those who often travel.

3G / 4G network

Even now there is a widespread cellular network (3G / 4G network) that can be accessed through certain cellular phones, and you can also share one 3G connection account with a number of people using a 3G modem and 3G router, call it DIR-450/451 from D-Link or Cradlepoint CTR-500.

The heart of a home network is a router. Even though there are two types of routers that encapsulate wired and wireless, a wireless router can do everything like what can be done on a wired router, and give up more flexibility and even the same price. Call it the E-Series wireless router from Linksys, or call it Netgear WNDR37AV for gaming and video.

Almost all wireless routers are equipped with at least 4 Ethernet ports, both Fast Ethernet or Gigabit Ethernet. With a laptop you can roaming all over your house without wires, or the PC is located next to the router can use wired connections for high reliable speeds. For convenience and wireless networking facilities is the answer.

Wireless Performance

The maximum performance of a wireless is obtained from the IEEE 802.11 standard specification. actual performance can vary, including lower wireless network capacity, data rate throughput, coverage and range. Performance can depend on not a few factors, situations and variables, classified as distance from the access point (base station), network traffic volume, construction and building materials, operating system used, combined or used wireless products, interference and other situations.

Standard Wifi

Here are some types of 802.11 wireless standards

Wireless-A (802.11a)

The 802.11a wireless standard operates at a frequency of 5 GHz which is not quite booming compared to a 2.4 GHz freq where telephone and microwave can cause interference. Even though the speed is up to 54 Mbps, the range is only 25 meters. Wireless A is not compatible with wireless B / G and N because it operates on a different frequency.

Wireless-G (802.11g)

Almost the same as wireless B, but the speed can be up to 5 times up to 54 Mbps. You can mix wireless B and G, but you will lose fast performance from wireless G.

Wireless-N (802.11n)

Wireless 802.11n is the latest and very fast wireless generation of up to 300 Mbps and even up to 450 Mbps (for example in TEW-691GR from Trendnet). It is appointed with Multiple Input, Multiple Output (MIMO. Wireless N is very suitable for applications that are hungry for bandwidth like streaming HD video, voice and music.

Wireless AC (802.11ac)

Wireless AC is the fifth generation of WiFi technology that can penetrate speeds in theory to 1300Mbps at 5GHz bands. 802.11ac is the latest wifi technology that has begun to be adopted for wireless routers, wireless adapters or wireless bridges with aggregate speeds of up to 1750Mbps. Call it Netgear with R6300 wireless ac router, Linksys with EA6500 ac router and not a few more.

Dual band

Dual-band routers work on both 2.4 GHz and 5 GHz frequencies. Some wireless routers working between bands only or a number also work together in both bands. With dual-band, it will minimize interference and leave more bandwidth for software such as video streaming.

Building networks

Here are the requirements that you need to build an internet network at home or in an office.

Router

The router is the heart of your home network and it is a device that forwards all traffic to and from the internet and the opposite in your network. With the router you can also share an internet connection from your ISP to a number of computers on the network. Routers are also useful as a security layer from the threat of internet security.

High speed internet service connection (Cable or ADSL)
You can buy a high speed internet service from your ISP (internet service provider) for example from Telkom Speedy service. we can also create an Internet network using Cellular services. Of course using a router that is contradictory, say MEBR3500 from Netgear or MBR1200 from Cradlepoint. Common high-speed internet services are referred to as broadband internet to separate with dial-up.

Modem

Modems are useful for connecting broadband internet services to your computer so you can surf the internet and access your email. Depending on your broadband Internet service, either Cable or ADSL, you must adjust the modem. often the ISP spends a modem when you sign an internet service agreement at your home. A gateway router is an integrated device that includes the modem and router if DGND3300 from Netgear.

Network Adapter

Network adapters allow your computer to be connected to a network. if your computer already has an adapter in it you don’t need to buy it again. There are not a few types of adapters depending on the computer you are using.

For desktop computers:

  1. You can use a PCI adapter that can be inserted in your computer’s PCI slot by opening the casing of course.
  2. Or you can use a USB adapter with the technique of inserting it into a USB port on your computer without having to open the computer case to the point that it is more practical.

For Laptops you can use:

  1. PC Card (PCMCIA) which is the adapter for your credit card, tuck in your laptop slot.
  2. ExpressCard, an exclusive laptop that has an ExpressCard slot
  3. USB adapter, the most practical and simple.

To find maximum performance, you must compare the adapters and routers that you use. For example, the wireless router that you use is from the dual-band 802.11n standard (for example Linksys WRT610N or DIR-855 D-Link), then you also have to use an adapter with the same wireless standard that is a dual-band wireless N call it WUSB600N from Linksys or TEW-644 USB dual-band adapter.

Computers

Some instructions for DHCP Troubleshooting

The most vital DHCP service in a computer network, the skills to do DHCP troubleshooting are equally important for network administrators

At first glance

In a computer network infrastructure in an organization, among the important components of the support is the DHCP server. For that, it is very urgent for network administrators to be able to troubleshoot the DHCP server against any format of the problem related to the DHCP server, both the problems that arise due to configuration errors and DHCP installation, to the small problems that affect a computer that cannot receive an IP address from This DHCP server.

Verify the configuration of clients

One indication of failure of a DHCP is if a computer / client loses connection to the network resource-2 or if a client computer cannot get a connection to the network one time. Our choice is to make sure whether this comes from a DHCP server, from the client itself, or from another source.

Make sure the client accepts IP

One of the techniques for starting DHCP troubleshooting is from the client to ensure that the client receives an IP address from the DHCP server. You can do the “ipconfig / all” command line from the DOS prompt c: \> (if from Windows press the Windows key and R together, continue to type CMD and press Enter). Can be ignored the output of “ipconfig / all” indicates that there is a DHCP enabled = YES. This means that the TCP / IP configuration has been configured to receive an automatic IP address, and if the DHCP server is located then the client should be able to receive the IP address configuration from the DHCP server.

Or you can click on the computer image in the lower right corner and select the Support tab, you can note if a computer can accept the configuration from the DHCP server then the Connection status is “Address Type” = “Assigned by DHCP” (see picture)

Troubleshooting DHCP server

Use the “repair” button

In the picture shown that the computer still does not connect, it can be clicked on the “Repair” button. Or if you are one time watching a yellow triangle sign that does not accept the configuration from the DHCP server, then click on the “Repair” sign.

Do you know what the computer is doing with this “Repair” command?

There are 6 stages implemented by Windows when working on the “Repair” process, as follows:

  1. Do DHCP request messages to work on updating IP address leases. This is similar to the command “ipconfig / renew”
  2. Removing the ARP cache, this stage is the same as if we type the “arp -d” command
  3. Removing NETBIOS cache, which is the same as if we are working on “nbtstat -R” in the command prompt
  4. Delete DNS cache, which is the same as the command prompt “ipconfig / flushdns”
  5. Re-register the NetBIOS name and IP address with the WINS server. this step is the same as the command prompt “nbtstat -RR”
  6. Register the computer name and IP address of the client computer for the DNS server and the same as the command prompt “ipconfig / registerdns”

If the client is able to accept an IP address that matches the network and there is no message Warning there is an IP conflict, it can be considered that the client does not have a problem with the IP address.

 

Troubleshooting DHCP – IP Conflict

If the client is submitted an IP address that turns out to have been used by a different client on the same local network, a warning message will occur when the address conflict is present. we can also check the event viewer for this conflict address like the picture above.

If this IP address is from a DHCP server, then this business is a sign of a different DHCP on your network, or re-deployment from the DHCP scope suddenly-2.

Track other DHCP servers

To be sure, the dhcploc.exe command (found in Windows Support Tool) can be used to track the presence of foreign DHCP on the network (because there may be idle for DHCP servers). After you have assured the other DHCP server has been turned off, one time first raise the “conflict detection attempt” to update the client with the command “ipconfig / renew” or click “repair”. Or you can also use the command line “shutdown / i” to restart a number of remote computers at once.

Failure to find an IP from a DHCP server

If you find the output from “ipconfig / all” indicates the IP address of APIPA (169.254.0.1 to 169.254.255.254), or from alternate configuration, one time do “ipconfig / renew” or click “repair”. If the results are the same, this business indicates:

  1. There is no DHCP server / DHCP relay agent in the broadcast range
  2. Disconnect the DHCP server connection
  3. DHCP server scope is problematic

How can you make sure there is a DHCP server in the broadcast range? Because IP clients are obtained from the APIPA IP address, you cannot ping the DHCP server because of another network. APIPA in the range 169.254.0.0 – 169.254.254.254 with subnet mask 255.255.0.0. then you must submit a static IP address to the client computer that has this problem with the IP in the same address range as the DHCP server.

Use “netsh dhcp show”

If a static IP address has been configured, then you can ping the DHCP server. If you do not understand the DHCP server IP address, then at the command prompt, type “netsh dhcp show”. if the ping results to the DHCP server are successful – it means that the connection to the DHCP server is not a problem. If it can be ascertained that both points 1 and 2 do not have a problem, then suspicion can be due to the configuration of the scope of the DHCP server’s IP address.

If all clients do not find an IP address, make sure that:

  1. The DHCP server installation is perfect
  2. The DHCP server configuration is perfect
  3. Authorized was successful, must be from the Enterprise user admin or member Enterprise in your domain’s active directory.

To ensure the IP address scope is not problematic, then make sure that the active and non-ending scope is all used by clients. You can do the following:

  • Re-authorized if necessary.
  • Deactivate the scope then activekan again.
  • If the scope quickly runs out, reduce the duration of the lease time. This will accelerate the release of IPs borrowed by clients (especially those who are not active).
  • If the client fails, besides ensuring connection to DHCP is OK, make sure that UDP 67 and UDP 68 ports are not blocked

Sometimes a PC cannot also get an IP address configuration from a DHCP server even though the TCP / IP configuration has been set up to automatically receive an IP address. This often happens on computers that are used up on an internet connection configuration with ICS (Internet Connection Sharing). You must lure it first by submitting a static / manual IP address in the same range as the DHCP server. after that try pinging the DHCP server, if successful, return the configuration to “Obtain IP address automatically” and restart the PC, or rather do “ipconfig / renew” or click “repair”.

Troubleshooting
