Hi Mr. Walker, Finally ! I meet someone who is facing the same problem as I am. Lucky for me but unlucky for you ! Hmmm, I have no idea either. *Even the guys who work with this stuff don't have good clues* ... I don't know, if someone can tell me if I can get this to work without the NetworkManager with the traditional ifup/down commands ... but I am such a newbie ... :(
and the strange thing ! some how it used to work on it's own !!! :P On Sun, Apr 17, 2011 at 9:10 AM, Francis Walker <[email protected]>wrote: > No Wireless Connection > > I have the same problem as Junaid Naseer.
