WRT54G Wi-fi connects but no net access

Question

Okay, I've tried everything I can think of. I sincerely hope someone here can help me with a walk-through (Imagine I'm in the fifth Grade)on fixing this problem. I just recently got internet through Cox communications. I have two computers set up right now. One in the oliving room, one in my bedroom office. THe living Room Computer is a Dell Desktop running windows XP. THe office computer is a homebuilt Desktop running Windows XP. THis router is connecte dto the living room computer. The internet is running through it. THe bedroom computer can pick up the signal and connect to the router, but the internet refuses to work. The DNS suffix for the living room computer is tu.ok.cox.net. The DNS suffix is missing from the ip configuration of the office computer. Ipconfig /release /renew does nothing to fix the dns suffix. I tried pinging yahoo.com but it doesn't ping. I don't know what to do, I'm at my wits end witht his thing. I've reset the router, the modem, turned off the computers, reset the router to factory defaults..still nothing..it doesn't want to let my office computer connect to the internet. PLEASE HELP! I've downloaded the linksys firmware upgrader, but it says my router isn't compatible. Below is tyhe living room Dell desktops ip configuration.

Answer 1

get into the basic setup in the web-based config pages. Check out the DHCP server enable/disable and the Start IP address Are you sure you haven't crossed the wires to the living room PC? This info that you gave, looks as if the the PC is wired directly to the DSL/cable modem and the router is not being used: Connection-specific DNS Suffix . : tu.ok.cox.net Description . . . . . . . . . . . : Intel(R) PRO/100 VE Network Connecti on Physical Address. . . . . . . . . : 00-11-11-86-70-A1 Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 70.185.195.109 Subnet Mask . . . . . . . . . . . : 255.255.248.0 Default Gateway . . . . . . . . . : 70.185.192.1 DHCP Server . . . . . . . . . . . : 172.19.57.19 DNS Servers . . . . . . . . . . . : 68.105.28.11 68.105.29.11 68.105.28.12
