Internet Connection Sharing |

Learn how to connect multiple computers to the Internet. Ok so you've got your PC connected to the Internet over cable or xDSL or any kind of technology. When you buy a new computer and you want Internet on both of them it always comes to the same problem: how do i share my Internet connection? Well there are two major possibilities: to buy a router or to use the first PC as a server for the other. Either way, the main idea is that you need a device that knows to route packets from one network to another, and a basic switch cannot do this. A. Internet Connection Sharing using a router The first thing you should consider is your connection type when buying a router. Some connections (like ADSL) work on protocols that require some kind of authentication (eg PPPoE - Point to Point Protocol over Ethernet). This assumes that the device that connects to the Internet Service Provider must know to work with something like that. Most of the routers available have this options, but better safe then sorry so ask before acquiring it. The router has two interfaces that need to be configured. One is the WAN (Wide Area Network - links you to the Internet) and one is the LAN (Local Area Network - links your PCs). The WAN must be configured (don't worry, it's all done with a web-interface wizard in easy steps) with your Internet settings (like IP address, subnet, gateway, DNS servers, and possible authentication issues. After doing this, your device is connected to the Internet.  Now you have to connect the two PCs to the LAN side of the router. You'll need two straight through cables (PC1 and PC2 to router) that usually come in the router's box. This also works as a switch, so you'll be able to share files between them. I strongly recommend to use the DHCP (Dynamic Host Configuration Protocol) available on almost any router to automatically assign addresses to local computers.  After doing this, go to your PCs and select in your Network Connections the active connection and then right click it - Properties - TCP/IP and be sure it's selected to get it's IP address and settings automatically. You should now access the Internet from both computers with no problem. If the router doesn't connect, it could be a restriction based on MAC addresses (network card's hardware address). If you think this is the problem, contact your Internet Service Provider to resolve the issue. B. Internet Connection Sharing using a computer Firstly, you need two network cards on the computer. It will work exactly like the router with a WAN interface and a LAN interface. Now the easiest way available if you are using Windows XP is to go to Network Connections and select the "Set up a home or small office network" link from the left panel. This will open a wizard that will guide you in completing the task. If you don't want to use the wizard, you just need to configure the ICS option. First go to Network Connections and select the two connections, right click and select the bridge option. This will make the two cards aware of each other. Now right click the connection to the Internet and select Properties. On the opened box, uncheck the Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks protocols because it's a security risk. Now click the Advanced tab and select the Allow other network users to connect through this computer's Internet connection. It's a good idea to enable the first option too if you don't have a firewall installed on the machine. Now all the computers in the network should access the server's Internet connection.  Note that the server must be powered on to share the Internet connection.

still dont understand how to do it. say one PC has internet connection via DSL. how to use it one the same as well as one more computer. both PC's have LAN cards.
written by Mihai Dobos , July 14, 2007
Hello If you have a connection using a DSL line it's probably connected like this: ISP - modem in your house - LAN. The best way to share a connection is by using a router. Simply buy a cheap router (Trendnet or so, should be ~30$) with 1 WAN port and 2 LAN ports. Now connect the DSL to the WAN port of the router and the two others to the computers in the networks; the router acts like a switch in LAN plus forwards packets between networks (your LAN and the Internet in your case). The router is very easy to configure using it's Web Interface and manual. If you're using DSL, you probably authenthicate by dialing with an username and password to connect. If this is the case (PPPoE auth.) check if the router supports it before buying. If it does, you can then configure your account on the router. If you have any more questions on this subject, just post them here. Best regards.

how to show all connection with my computer in networking
written by Mihai Dobos , July 18, 2007
Hello If you want to see all connections (sockets) opened from your computer to other systems, go to Start Menu - Run and type cmd. In the Command Prompt Window, type netstat.exe and wait for the output for a few seconds. You can see there protocol information, local and foreign addresses and ports uses. The last flag is used to determine the state of the connection. Established means active connections and *_WAIT means that the connection is in open/close negotiations with the other peer. Best regards.

Hi,i hav two PCs & a Router.At d back side of Router there is an USB(Square size Port)& one PC is connected at the Front.Then how to connect two PCs through Internet?Giv me full detail.......... Thanks
written by Mihai Dobos , August 06, 2007
Hello Probably your router is set to allocate a private address automatically using DHCP so you can connect another computer to the Internet bu connecting it with a straight-through cable to the back of the router (exactly like this first one is connected). The usb port is probably to extend the router's memory by pluggin in USB memory stick. Best regards, Mihai D. Tutorial5.com

Before i format my computer i was using two card with WAN and LAN but now there is no WAN i can only see LAN. why ?? and How i can get the WAN back so that I can share the Internet Connection to my other computers.
written by Mihai Dobos , September 07, 2007
Hello Please check that your Network Interface Card that was on the WAN side is installed (drivers) and configured (IP addresses, etc). Go to Control Panel - System - Hardware tab - Device Manager and check if it's in the list and any flags next to it (an exclamation mark would state a problem with it). Also check if you are logged in an administrator account to get the privileges needed for Internet Connection Sharing. If all this fails, remove the network card and plug it back in when the computer is powered off. Turn on the computer and see if there are any changes. You can also look on the back end of the computer to see if the link (usually a green light) is on; if the cable is connected and the link is off it's a hardware problem (NIC or layer 1 - cabling, etc.). If all this fails, test you network interface card on another PC; it could be hardware malfunctioning. Best regards, Mihai D. Tutorial5.com

I want to set up LAN in a room of 5 PC with a printer sharing. How do I start.Ive no backgroung in network
written by Mihai Dobos , September 10, 2007
Hello First buy a basic switch with 8 ports. You can use a Trendnet device or so, it's cheap and works very well. Plug it in and then connect all the other computers to it using straight-through UTP cables that you can buy in any computer shop. Go to every computer and set up the network, by assigning them with IP addresses (use something like this: PC1: 10.0.0.1, PC2: 10.0.0.2 and so on). Put the same subnet mask on all of them (use the default network mask of 255.0.0.0). If you have no Internet connection (just LAN), you don't need a default gateway or DNS servers. To share resources between all your computers (asuming that they run Windows XP or something similar from Microsoft), be sure that they are in the same Workgroup. To do this, go to Start - Control Panel - System Properties - Computer name tab and check the settings (they should have different computer names and the same Workgroup). To change any of this, click the "Change button". To share a printer, install in on a computer as a local printer. Now go to Control Panel - Printers and Faxes and right-click the desired Printer, selecting Sharing. Configure that and you're ready to go. All computers should find the printer now in Network Places. If you have any other questions, reply to this comment. Best regards, Mihai D. Tutorial5.com

Hi, I'm from India. I have one ADSL router ("D-Link") which is supplied by my telephone company who are my ISP too. It has one outlet for LAN cable and one for USB cable. At a time only one of these functions. I have one desktop and a laptop. Desktop does not have a LAN card. Hene, I have connected ADSL router with USB cable. I want to use the same router and I want to operate internet simultaneously on desktp as well as on laptop. Since, I don't have a LAN card, I can not connect two pc's via LAN cable. My question :- If i purchase a HUB or SWITCH, then can I connect output of ADSL router to HB/SWITCH and the output of HUB/SWITCH can be distributed to two (PC & Laptop). Rgds, Niko
written by Mihai Dobos , September 16, 2007
Hello As far as i can see, you have 3 options in your case: 1. Talk to your internet service provider to supply you with an ADLS router with at least 2 LAN interfaces. They should be able to give you one. This is the easiest solution. 2. Buy two network cards for your desktop and connect the ADLS router to one of them, then the laptop to the other (or buy at least one and share the USB connection to the network interface card). Share the connection for the laptop using Internet Connection Sharing. 3. If you buy a switch, contact your Internet Service Provider first. They could allow only one host at a time to connect to the ADSL service. If they say it's ok, you can connect the two devices in the switch then uplink the switch to the ADLS router; in this case, you will need a network card on your desktop PC. Mihai D.

hello i have two pc at home 1 has a internet connection provided by a network company. i installed 2 lan cars on it and the third one on the other pc.the ip adress provided by the net provider is 192.168.0.27 sub mask is 255.255.255.0 and the default gate way is 192.168.0.1 now what proxy should i give to the other lan card and the other ps's lan card please tell me briefly i would b very thank full to u regards sajjad raza
written by Mihai Dobos , September 19, 2007
Hello If you want to setup a proxy gateway for your network, you must install a proxy server to the host that connects to the Internet. This means that your proxy's IP will be 192.168.0.27 and will forward all traffic to 192.168.0.1. You can install a proxy like WinProxy (search on Google to download it) or Squid (for a Linux station). However, this is not the best solution if you want to share an internet connection. Use this only if you really want to setup up a proxy service on your network. To share the internet connection, use the ICS wizard provided by Windows XP like mentioned in the last part of the article. The simplest way for you is to run "Setup a small office or home network" wizard available by clicking the link in the left panel in your Network Connections window. This will configure the server and the client automatically, detecting their needed settings. Hope that worked for you. Mihai D.

How can this be posible? desktop pc - cable modem(default Internet connection) - connected to the Lan netword
written by Mihai Dobos , September 20, 2007
Hello farhanharon To configure an ADSL router, check it's manual for detailed help. You must connect to a http local address (like http://10.0.0.1 or something like that - see the gateway of your PC connection) and login using an username and a password provided in the router's manual. Usually they are built to be "plug and play", so you just connect the devices and it will assign IP addresses automatically. Regarding to membership, you can Register by clicking the link in the bar on the top of your screen. Mihai D.
written by Mihai Dobos , September 20, 2007
Hello Pat Cab If you want to join your PC in two networks (local LAN and the Internet), you must have a computer with two network interface cards. One connected and configured to be a part of the LAN (IP address, subnet mask, gateway if needed) and one configured to connect to the Internet. You can share the Internet connection to the LAN afterwards. If you need further help, please leave a more detailed comment. Mihai D.

I have a Linksys wireless-G Broadband Router with a 4-port switch. My concern is this: I want to use a bandwidth manager application but my understanding is that first i have to share the internet(hughesnet satellite dish) through another computer( using two network cards). Which I think I can do. My question is this: How can I make my router work or configure it to work behing the main computer?
written by Mihai Dobos , September 22, 2007
Hello As far as i understood you want to limit the bandwidth using a PC becouse your wireless router doesn't have that feature. If you want to put a computer to link to the Internet and then share it with the router, assign a WAN IP address manually with the default gateway = PC's network card, and DNS servers that your provider told you to use. Than bridge the two connections (Internet and LAN - link to router) on the PC to configure Internet Connection Sharing. Install any network management and monitoring software on the server; the router part should be almost plug and play.. connect the devices (in the ports or wireless) and they should be routed to the PC and then to the Internet.

I have D-link ADSL Moden Router.i want to share internet with 15 pcs. So which is the best way to connect? what is the Advantage of two network card? * before i connect 16port switch to the router(DHCP Enabled) and internet was working in all the pcs.but after some time its started giving me many problem like limited conectivity and though router is conncet but i can't able to access internet. So please tell me the best possible way to connect?
written by Huzefa , September 27, 2007
Please replyyyyyyyyyyyyyyyyyyyyyyy
written by Mihai Dobos , September 27, 2007
Hello Sorry for the delay in this answer. If you need to connect the PCs to the Internet, the scheme you selected is probably the best. The "Limited or no connectivity" message usually appears when a DHCP client cannot obtain it's network settings from the server. Check if the ping goes to your gateway and if the router is up and running (check the status, logs, whatever options are available). If it all worked fine, and then the Internet connectity was lost check try first to reset the router and recheck all cables to see if there is workable connectivity to the router. If it's all ok and the router still crashes from time to time, check the technical manual of the router (or contact the ISP if they provided it) to be sure it can handle properly 15 clients in peak times. A standard router like D-link, Trendnet etc (designed for home users) usually works fine for 4-5 client or so; if you use peer-to-peer connections from the computers to the Internet (file sharing - many transactions/second) it can crash even if you use 2 clients. Try buying medium business (Linksys or so). If you still have problems, please reply to this comment. Mihai D. Tutorial5.com
written by Huzefa , September 28, 2007
Thanks for your reply, As you said, D-link router are not capable to take load of 15pcs.So is it better to use computer as a server and install two network cards on it. is it decrease the load on router?.b'cos we do share files and resources also.
written by Mihai Dobos , September 29, 2007
Hello If you want to configure a server to act like a gateway to your office, that's fine but you'll need to configure it properly. A server has more possible failure points (hardware&software) than a dedicated routing device. My recommandation would be to get a Linksys wired device (go to http://www.linksys.com/ and browse there). Their products are designed for small buisness usage exactly like yours and should hold up with no problems any traffic demand on peak usage. If you'd rather want to setup a network sever to act like a gateway on Microsoft, use a server edition (Windows 2000 or 2003) to configure it as a DHCP server. The connection bridging and Internet Connection Sharing is the easiest part. Mihai D.

Hi I have a network of 4 computers connected through a switch. I have assigned a IP address to each and created a workgroup. Now I have taken a DSL internet connection, which is connected directly to the switch from the modem. I can use it on any system by changing the settings to automatic IP address as the IP address is assigned by the DHCP server of ISP. But I can use only one system and we are not able to share it over LAN. It is restricted to one MAC address only at a time. Now i am looking for a way to connect them all with sharing internet please guide me.
written by Mihai Dobos , September 29, 2007
Hello If your ISP gave you a connection that is available for only one MAC address, then you are practically stuck with it. You could put another router behind the ADSL to act like a "host" that connects to your ISP, and then only one MAC address will appear externally. Then change your router's WAN port MAC address or notify the ISP that you changed your network card and give them the new MAC. This can solve your problem, but it may create others (if the provider finds out, it could cut off the connection without any notice or so). The best way to do this is to contact the ISP and ask for a 4-host permition; maybe there are not additional fees involved. Mihai D.

Hey! Thank you for your advice. I tried asking for multiple host permission n they are skin for extra money hence i was looking for a way out. Can i do something using a proxy server. If i understand correctly i will have to put up a router between the modem and switch. Then the router will assign the IP address to the various clients.
written by Mihai Dobos , September 30, 2007
Hello Yes, that's exactly what you have to do.. They will see only one host connecting to their ADSL device, your in-LAN router. This should solve your problem. A proxy server will run on a server, and could get you in some problems. HTTP proxy servers don't allow peer-to-peer, you will need a SOCKS server for that. It's a long way shot, since you'll have to configure all software afterwards to use the proxy. Mihai D.

Hello If you don't have a built infrastructure yet, i suggest to buy a wireless router to skip the cabling part. Use a LinkSys solution, it's made for small business usage. For the PCs buy some USB wireless adaptors. Be sure to make the network secure by using encrypting WEP2 keys. To filter unwanted traffic just choose a router that supports control lists (denied web traffic and web domains, etc). Almost all equipments can handle this kind of options.

Please let me know all details as I am totally new to this networking works..

Hi, I recently purchased a computer to use in another part of the house. I thought we could just purchase a router and then we would have a internet connection to the new computer, but it says we have to connect to the cable/dsl modem (which is in another part of the house). What's the best solution without moving the computer next to the other one?

I'm having trouble setting up "ICS using a computer" (scenario B above). My desktop PC (Windows XP) connects to the internet via a wireless network card (802.11), Wi-Fi rural broadband service (i.e. NO DSL or Cable modem). I want to share this internet connection with my wireless laptop (Vista Home Premium), so i bought a LinkSys WRT54GL wireless router. On my desktop PC, I've enabled an unused on-board ethernet port and connected an ethernet cable to the WRT54GL. I'm aware that on the desktop PC (ICS) I need to "bridge" the wireless internet card and the ethernet connection to the WRT54GL, and then enable ICS. The problem I'm having is with the setup of the LinkSys WRT54GL. All I can find are instructions for connecting the WRT54GL to a Cable or DSL modem. In my case, I have no modem, and wish to connect to the internet through the desktop PC (ICS enabled). Do you have any setup instructions, or links on how to do this? I can connect into the LinkSys router's setup web page, but then am unsure what settings to use from there? I'm very frustrated. Appreciate any help you can give.

Hello Rob, Mihai already answered all questions and I think I should lend you a hand with this one. First of all, I do not understand why you want to connect the Cable connection to your computer and then to the router. You could as very easily insert your Cable connection into the Internet port on the LinkSys router, connect your computer via wired connection and your laptop via wireless. If for example you would additionally need some special port features the LinkSys WRT54GL can very easily be configured to port forward traffic to your internal IP Address. See this link www.portforward.com/english/ro...s/WRT54GL/ If you really do want to configure the router in your desired way this is the way to do it: You do not even need the second Ethernet card on your Vista Desktop. You would just enable ICS on your internet Ethernet card and then add an alias to your IP address using a unused class 10.10.10.1. Then in the router configuration you would set your "Internet IP Address" to 10.10.10.2 your Subnet Mask to 255.255.255.0 and your Gateway to 10.10.10.1 In both cases you need to enable DHCP on the router and on the Laptop .

Hi, i would appreciate help on my problem: heres my current set up: cable Router(from router to these below mentioned)(i have a Dlink wbr1310) | Vonage, lan, wireless Heres the problem, when i travel, i want to be able to connect my Vonage, THROUGH the wireless connection in the laptop. Heres what i thought, connect the laptop, via wifi, then enable ICS, and hook up the vonage to the ethernet port into the laptop. But, i have 2 issues: 1.In my wireless connection settings, in the advanced tab, i dont have any option AT ALL to enable ICS! i only have a link from there to the firewall settings! 2.when i try to enable ICS on the LAN settings, it gives my an IP sharing error! i'm stumped, ive tried changing the IP of my laptop, ive tried disconnecting everything from the router except laptop, but i think my router has the default 192.168 ip. So, i tried randomly connecting to other wireless networks, since going through the router seemed to be the issue. Firstly, i dont even get a connection with that, second, it still continues to give me IP sharing error. PLEASE SOME ONE HELP ME! , i'm travelling soon and am really at wits end here! thanks much.

written by Mihai Dobos , January 19, 2008
Hello Mallika A better way to do it if you carry the laptop and a router is to get a wireless router that also has some ethernet ports included - to connect both wired and wireless devices; that will save you the time to connect the laptop to the router and the other device to the laptop; since home user routers (Dlink, Linksys, Trendnet) are not so expensive (about 30$), it's a really good option to save you the trouble.
written by Mihai Dobos , January 19, 2008
Hello Ricky If you want to apply some outgoind restriction, it is better to do so on the router configuration (some MAC access policy or so); this is the safest and yet easiest way to do it. If you want to configure advanced security for your network, build a Linux machine to act like a gateway for your network and you can set many options using iptables and other services. Best security yet is a dedicated hardware firewall (for example a Cisco PIX solution).

Hey, Is it possible to use both my USB and LAN adapters on my modem to create two different network connections with the same ip address? It only allows data transfer on one connection because of the same ip. My friend does this to get double the speed. God knows how. Please help. Thanks in advance.
written by Mihai Dobos , January 27, 2008
Hello Jonathan Well you can connect twice to the modem theoretically; but: 1. You computer will route the packets to only one of the connections, so the second it's useless. You can make some kind of load blancing to send data both connections, but you it's a long shot. 2. Even if you manage to do the load balancing and use both connections, this is appliable to the network between you and the modem. The modem will still use the same speed to connect to the ISP, so your friend doesn't use a doubled speed; if you want to test this, simply use a bandwidth meter (like http://www.speakeasy.net/speedtest/) to test his connection both ways: plugged in to the LAN, and plugged in to both LAN and USB ports. You'll see there is no difference. If you want to boost your Internet connection speed, you can upgrade the bandwidth provided by your ISP.. It's the easiest and yet the only way to do it.

Hello Brendan That probably means that ICS is not installed on your system. To install it, insert a Windows CD, then go to Control Panel - Add/Remove Programs - click the Windows Setup tab - click Internet Tools and tick the Internet Connection Sharing package. Restart your system and it should work.
written by Mihai Dobos , January 27, 2008
Hello Luis The best way to see if the modem can act like a router too is to check how many network interfaces it holds. If it has only two: WAN (cable) and LAN (ethernet) - well it's probably just a modem. If it has more then one LAN interfaces (usually four) then it can also route your packages. Try searching on google or on the vendor's website for a better usage manual.

here is a tricky problem I been having since I build this new computer.. It has 2 NIC cards.. Cable modem connects to the first nic, then I have my second nic going to a HUB. works fine for a little bit, But then the network computers go down. (can't access the internet) Odd part, You can still see all the network shared files/folders. So it's just the internet they can't get to.. Only way to get a temp fix on this problem is disable my first nic card that connects to the modem, then re-enable it. Then the network is back online with the internet. and a little later, it will go out again on me. It's not my NIC cards, I replaced both and same affect. I'm completely lost on what is causing this.. My network computers are all running XP pro SP2.. Any ideas of how to resolve this issue would be greatly appreciated

I have two internet modems in my house, I have a PC that connects directly to one of them and I also wish this PC to be part of my LAN for file sharing. The PC has two network cards and If I enable both my internet connection goes down, I am guessing a conflict problem. So I want one card directly connected to the cable modem and one card connected to my router, but obviously only able to file share not internet share. I know its weird but this is how I want it. If you can help-many many thanks
