Hello :) having a bit of a problem with this, i am fairly new to ubuntu, but been using linux to and from the last 10 years. Now i'mm trying to install ubuntu on my parents laptop, it is working so far perfect with the exception to wireless.

Problem: Wireless Intel 3945ABG will not connect to network.

Have tried different solutions on the forums, including, no encryption on the network, Wicd, manual connection and some other solutions.
So far the only result is that the wireless card is trying to connect but doesnt get any result, with network manager i only get the box stating the network needs a password....etc.
This works on the same machine with Vista, the network is working on another machine with Ubuntu 9.04.

Have provided as much output as i know how to, if there is anything else , i will try to provide it.


This is at the moment a clean install of 9.04, with upgrades from the upgrade manager only.

Machine: Packard Bell easynote laptop
Router is a Belkin Wireless G plus.
