I am using win xp with sp2 on an amd 1.3 ghz processor.
Computer could not connect to the internet after installing zonealarm, I set permissions properly, but no go..so went to add / remove programs and uninstalled zone alarm then restarted the computer several times..still would not go. Uninstalled sp2 and still no go. Eventually had to reinstall the operating system and put back in sp2 and still cannot connect with wired or wireless routers...everything else works fine. Can get the ip address of the network card and the router.with ipconfig, but cannot ping the router.
When I connect a laptop to the same cable I have a perfect connection.
There are no firewalls on and I have minimum startups in the background.
I did notice in device manager that there are 3 other network cards listed that I cannot uninstall...so I disabled them !
