Hey everyone,

im running Ubuntu 12.10 32bit - 3.5.0-18-generic i686 on a Dell Studio 1558 with Core i5-520m, 4gb ram, hd 5470 mobility and a dell mini 1397 wireless card.
The first attempt of connecting to the wpa-secured network succeeds but the connection went down shortly after.
The following attemps are not successful resulting in a loop of "the entered key is incorrect".

Since i cannot connect to my wpa network at home i tried the workarounds given on linuxwireless.org with no efforts.
Currently im using a lan cable to provide the connection to my router.
Sometimes a connection is built up but no data can be transmitted and the connection shortly after went down.

Below this i added some logs maybe some of you can read anything out of them.
