I am trying to solve this problem on the XP form to no avail so I thought I would try here. I have 2 systems running WinXP. I have recently purchased a Linksys Router. I have a single DSL line in which the ISP has informed I do not need two IP addresses to hook up multiple systems. I originally was able to set up both computer in a LAN set up with no internet connection. I have since been able to get one system configured to the router and connected to the internet, but now my second system will not even connect in a LAN set up. I have tried releasing the IP and will not work. I have tried un/reinstalling the Ethernet adapter which didn't help and also manually configuring the IP/DSN/etc which allows me to at least ping the router, but nothing else. Any suggestions would be greatly appreciated. tia

Basic setup should be as follows: Router: WAN IP Address: Dynamically assigned by ISP LAN IP Address: 192.168.0.1 Computer 1: IP Address: 192.168.0.2 (or dynamically assigned) Gateway: 192.168.0.1 (Router's LAN IP Address) Computer 2: IP Address: 192.168.0.3 (or dynamically assigned) Gateway: 192.168.0.1 (Router's LAN IP address) If you can ping your router, it's probably an issue at the router, but may also have to do with your network settings. Without more information (specific problems or errors, brand of router, current network settings for each device, etc.) it is difficult to troubleshoot this problem.

Thanks for the response. The Linksys 4 port router uses a default gateway of 192.168.1.1 Both computers have that designated. The IP address I have configured to 192.168.1.100+ So computer 1 is at that IP. I have tried setting my second computer with an IP of 192.168.101 or any other variable up to 150 as is my 50 IP numbers. Now...my second computer for some reason will say that I'm connected to the internet if I bypass the router, but I cannot do anything internet related (ie. IE window, Kazaa, Messenger, etc) All 3 lights indicate that my computer is connected to the router correctly. I have changed my connecting cables to no avail. As I said earlier, I was even able to connect to my other computer via the LAN, but for some reason it just stopped communicating with the router after I got the first system on the internet. I have powered down both the router and modem as well. Reset the modem and set up from scratch again. The first computer has no problem with the default settings associated with the DHCP, but the second one still will not. I hope that maybe clears my problem up for someone.

By 'bypassing the router' do you mean hooking that computer directly up to your ISP/modem? Is the XP firewall blocking the ports? Can you ping addresses outside your LAN? Is the computer correctly getting an IP address from the DHCP server, including DNS server information?

Yes...sorry. I meant hooking the computer directly to my modem and logging onto my ISP with the user name and password. XP firewall is shut off. I cannot ping anything outside of my LAN. Just Computer 1 and my modem IF I manually configure my IP/DNS/Gateway. The computer is not getting the correct info from the DHCP server. It keeps coming up with the default windows IP. (169.***.***.**)

Things to check: 1. DHCP Server on Linksys router is configured to hand out more than one IP address. (I believe you already mentioned it was.) 2. DHCP is configured correctly on computer. 3. It's not a hardware problem (try swapping the NICs). A quick fix is to manually configure the network settings rather than using DHCP.

I have doubled checked that the router is configured to hand out more than 1 IP. The DHCP is configured correctly as far as I know. I cannot swap NICs because the one on computer 2 is an onboard card. I have tried to manually configure all the network settings and that was the only way I could ping the router, but I was still unable to connect to the LAN or ISP. I am out of ideas and that is why I have resorted to posting on here. I can't see the card just not working no more especially if its a new motherboard and all the router lights indicate that it is hooked up correctly.
