Exact same problem here with a D-Link DSL-G624T Routeur. No internet at all and setup through Network Manager doesn't help.
Now I managed to make OpenSuse activate the network but the browser just never loads the pages.
Any idea ? I'm running Suse 11.
Sorry to ask this here but as it seems we have similar problems, I thought it was a good opportunity not to flood the board with newbie questions...
