Having problems setting up linksys router

If anyone can help me that would be great. I am trying to connect a linksys wrt54g wireless router and am having the worst luck with it. I have tried resetting it, and nothing changes. The power LE, port 1 led, and internet leds all blink when everything is hooked up properly. I have tried the disk, windows network wizard and cisco network magic and none of them were helping. I try the web setup and it tells me that the connection timed out, I have tried pinging the router from Command Prompt. Any help would be much appreciated.
Thanks.

 

What System are you running ?

What type of Internet do you have ?
Dial-up

My operating system is XP Mediacenter Edition. I have cable internet through comcast.

 

You may want to go to this web sit and download firware and driver update
http://www.linksysbycisco.com/APAC/en/support/WRT54G
then reconnect the router and apply the firware update 1st and then the driver updates.

 

I already gave up...buying a new router. Thanks though for your advice.

 

I have had several dead out of the box. Mostly the WRT54G.
