Since Microsoft's XP doesn't get all the right drivers tell us about your XP install. Drivers you added and more.
Also, did you test your USB wifi on another PC?
Today i decided to revive my internet connection on my dell computer that runs on windows xp. I started by completely reloading windows xp to clear the system off all programs that could block the recieving of packets.
I am using wireless usb linksys software version 1.05 which i am connecting to my westell wireless router model 327w (the router is fine).
No its not the firewall because i havent installed one yet.
PLEASE HELP!! Your comments will be appreciated!
