He has a Dell PC running XP.
Linksys Wireless internal card
Linksys Wireless Router
Connection from a 2nd PC tied directly to the router or to the modem work perfectly.
Connection from this PC either via the wireless adapter or through the built-in ethernet port both result in the same problem. No IP is picked up, no default gateway. It detects the signal on the wireless card and sends thousands of packets but receives 0 in return.
No big deal, I tie the computer directly to the wireless router via ethernet cable and the same problem. It wont pick up an IP and I cannot access the routers admin page (192.168.1.1).
A second PC works perfectly.
My friend says this PC was infected by some viruses at some point but that he had the OS reloaded. Any ideas where the setup is wrong or where there may be a virus problem? It used to work, even after the OS reload, then suddenly stopped one day.
It is all set to detect IP, DHCP, DNS automatically, all the usual suspects have been checked.
