Hello,
I've got the problem yet - and I don't know why.
Everything uses my Internet connection - browsers, online games etc. - but the system update manager always gives me an error about no network connection.
This is the same when I wish to install a .deb package from the PC. But when I use Terminal commands - for example apt-get install .deb it always work with the same network connection for downloading packages.
I'm using PPPOE connection with dsl-provider - and I wish to use that for the future too.
Thanks for helping
