I am not sure if this is the right place for this question, but I currently am running Ubuntu 10.10 and have windows installed with the dual boot option. My wireless card is the Dell Wireless WLAN 1397 Minicard. When running Windows, it detects and connects to all the available wireless networks that I have access to. However, when i boot into Ubuntu, it connects to the wireless networks only sometimes, other time ,on entering the username and passphrase, it tries to connect for about a minute and then fails to do so. I read the following on a forum as a temporary fix:
I Should turn the system off, remove the battery, reconnect and turn it on again.
This always works, but it really inconvenient and sometimes, looses connectivy after about 5 minutes of having connected. I would like to point out that it worked fine when I was running Ubuntu 10.04
Any help is much appreciated.
