Lost DSL Connection

Hello, Everything was working fine until I upgraded my DSL through Qwest. I run the DSL via Ethernet and it should be working in SuSE as it did before, but it is not. What settings do you think I need to change? Funny thing is, when I run Limewire the connection is there, but anything else doesn't work... mozilia,suse update,gaim. The connection is there and works great when I boot into windows. Any ideas? Thanks, SuSE Noobie
