I recently installed Dapper Drake on a really old spare computer (upgrading to a newer version is no option -- tried it, it gets too slow). All went well, except for my attempts to get Wlan up and running.

Whenever I install the drivers for my Siemens Gigaset 108 adapter, the device works properly for like 2 or 3 minutes. I never got to configuring the connection, however, because the device then drops from the list. Reinstalling it works fine, but only for this cycle to repeat itself

Anyone has any idea what could be the matter? Keep it simple please, since I'm a relative linux newbie.
