[ubuntu-uk] Lost Wireless Connection after upgrade

[A J Binnie]

Hi folks,

I've been running 10.04 for a while now, and everything was working
fine until the last round of updates. Now I've completely lost my
wireless connection. The network manager menu has gone from the
top-right hand corner of the screen and I appear to have lost the
ability to do anything that requires authentication. For example, if I
try to install anything from the software centre, clicking on the
"install" results in no action at all. Even something as simple as
changing the time won't work.

I can still do stuff from the command line using sudo, but I'm not
exactly a wizard with the command line!

Has anyone else experienced this?

Regards,

Gus
