I'm on a new install of Kubuntu 9.10, using wireless internet.

It works completely fine when a wireless router has no security on, but as soon as I turn on the security (and configure it inside linux with the password/correct type), it refuses to connect. This has occured with my and 2 of my friends routers, linksys and belkin, WEP and WPA. Any ideas as to why this would occur?

If it matters, I'm running an Alienware m17. Let me know of any konsole printouts that would be useful.
