[SOLVED]Unable to use wireless connection

[hakiza]

Hi all,

Need some help:

My Kubuntu 11.10 runs on Dell inspiron 1520 (laptop). No problem with wired connection, but I cannot use wireless connection: When I click on "connect" on the WiCD (after that I have written the correct Pre-Shared Key for WPA2), I get info that it's a bad password!

Here is some additional info:

Re: Unable to use wireless connection

Search the forum for wicd "Bad Password". I'm pretty sure this problem has been reported before and the solution has been posted.
