If you have a router that was made along time ago, chance is the router isn't compatible with Windows 7, for instance i use a Wireless-G Broadband Router WRT54G, and it isn't compatible with my built computer.
It used to work. On Windows 7. So why would it not anymore? Its a Linksys Wireless-G Broadband Router WRT54GS. Does the S at the end mean its different?
Also, I can't turn UAC back on. Its a piece of loving stuff that doesn't let me make custom add-ons or download new ones, or do anything for that matter.
