Hi

To TA-t3:i used a 26 chars code like FE3F 87E5 [....] and also a 9 or 10 chars passphrase.

To slender: nope, a friend of mine installed it for me at my home, I am not into networking and had some issues while installing it, so I asked him for help. Thanks for your idea, I will set my home WiFi to WEP and try to recreate the situation from work at home.

To Walker: thats what I did yesterday, I had no connections at all in the internet connection settings, the failed connection was the first one to create, then when i came home I was lucky with my WiFi.
