I'm a newbie, escaping the Microsoft tentacles and I recently installed Ubuntu 8.10 on my laptop. I have a Blitzz Wireless card that will connect to my wireless network when I boot up, but the connection will only last 5 minutes, if I'm lucky. After it disconnects, I cannot get it to reconnect and I'm at a complete loss as to what is up. Any help would be appreciated, as I don't want to go out and buy a new card.

Here's the information on my system:
Dell Inspiron 8200
