How do I completely restore Wi-Fi settings and drivers back to Windows defaults? I installed an old Cisco VPN client (5.0.07.0290). It completely hosed up the machine I was working on. Once I figured out the issue was with the client, I fixed the issue on two other machines by restoring them back to before I installed the client. However on this machine for some reason there are no restore points prior to the installation.
I have uninstalled the client, but I'm still having the network connectivity problem.
My best description of the problem is this: when you connect to a wireless access point, Windows then reports "limited connectivity" on Wi-Fi. Rebooting, reinstalling TCP/IP, deleting the settings and readding, rebooting the WAP and then the computer do not work.
