Someone PLEASE HELP ME!

if you can't even ping then something is wrong with the cabling, is my knee-jerk reaction. could be bad tcpip stack but unlikely imho. do you have a link light? what if you swap cable and port with working xbox? you are not mixing up a crossover cable or something, also linksys doesn't like you to use all the ports if you are using the uplink port...maybe media type in pc nic?? try locking down to 10mb half duplex? but you would see no link light in these cases. if you are sure cabling is good, something is wrong with tcpip. you hve of course tried taking it out and reinstalling it...
as far as getting into router config. have you tried setting pc as dhcp client just to get started (ipconfig /release /renew after changing the settings.)

sgt shultz is right in that if you cant ping the router than it might be a cabling problem, BUT, you mention the pc has a static IP address AND that the routers DHCP service is running. Can't have both. Its one or the other but not both which is why your Xbox worked and the pc doesn't.

To resolve this problem, try this, click start,then navigate through,control panel,network & internet connections, network connections, to the local area connection. Right click local area connection 1. In the general tab click on tcp/ip . change from a static IP scheme to obtain IP address automatically. click ok. close all windows. I suggest you reboot your computer.
now your computer can obtain an IP address from the DHCP service on the router.

To access the router's setup page you do that with your browser. First open up IE and hit the stop button. Next click on tools and navigate through internet options, connections, LAN settings. Clear ALL the boxes. then click ok.

now you should be able to access the linksys routers setup page via IE. you do this by typing in the routers ip address in the address bar and click go. you'll see a small window open up requesting the user name and password. leave the user name blank and type in admin all lower case. then click ok. this should get you to the routers web setup page. note: you do not need to type in http://www when accessing the router. just type in the ip address 192.168.1.1 I suggest that you change that to something else within the 192.168.1.1 - 254 address range. Also change the admin password and disable the remote web administration feature.

I have tried both previous answers and I am still unable to find an answer. I have set up a 2nd pc with the same config to the router and didnt have any problem both finding The router and finding the routers config utility using IE. So the question remains, what could be stopping my other pc from getting DHCP from this router ( I have tried it with and with out static ip scheme ). It has to be an issue with the OS, a service that has been shut down maybe, an update from MS?, an incorrect setting. I have been down every other avenue and I am not finding the solution.

OK, so you have tried a static IP in the 192.168.1.0/24 Class C network, and you have also tried DHCP on this machine, and none of it works properly?
Ok, here is an idea I have, from seeing a similar problem. Check if the NIC on this machine is appending domain name.
Open up Network Connections window, to see the NIC.
Go to Properties on the NIC, choose TCP/IP and go to Properties on that.
On the General tab, click the Advanced button.
On the DNS tab, look in the "Append these DNS suffixes (in order)" box.
Are there any DNS domain names listed there? If so, select them all and Remove them. Click OK whenthey are all gone. Then just keep clicking OK until all of the windows are closed. REboot after this, just to make sure things are clean.
Then try it.
I have seen an improper DNS suffix make connectivity not work. I am not sure why, but I have seen that be the problem. REally weird!
hope this helps

Try this in IE type 192.168.1.1. That should send you to routers user name and password screen. Type "admin" to the password unless changed. That you are seeing the router. If that works go to your LAN connection TCP/IP properties and have it pick the IP automatically and have DNS servers pick up automatically. Then either restart the pc or go to the cmd prompt and type ipconfig/release and then ipconfig/renew. If thtat doesn't work restart the computer. Make sure that your LAN settings are Automatically Detect settings (IE, Tools, Internet Options, and LAN settings)

If you want static IP's I would change the address from 192.168.1.2 to 192.168.1.100-192.168.1.150 (by default allows 50 Ip address to connect through lan that can be changed)
And in you tcp/ip settings add the DNS server addresses.

Also befault the router is gives dynamic addresses starting usually at 192.168.1.100

Hiya,
I think you've answered your own questions ... and believe that the problem you're experiencing is based around the fact you have a "Static IP" address, the X-Box uses a dynamic IP address ... try using dynamic, and then reboot the system the router should provide an IP address for you ...

I has a similar experience recently using a Cisco Router ... and spent a few hours on the problem ..
