I set up my Netgear router to use wpa-tsk security with a password. When I
couldn't get it to work in Kubuntu I reverted to the previous, unsecured,
settings. That still works just fine with the Windows XP that my MSI Wind
came with. However, in my fumbling around in Kubuntu I must have messed up
the drivers for the wireless net card and now it isn't even showing up in
the list of network adapters.

I'm sure there is a "best practices" way to restore them and I'm just about
to remove and re-install everything that looks like wireless support.
Fortunately the wired internet connection still works...

Any works of comfort or advice?
