How to set up a PPPoE connection under SuSE Linux 10.1
 

I have SuSE Linux 10.1 and I configured my ADSL(PPPoE) connection via YAST. The Kinternet icon shows that I'm connected, but I cannot open anything on Firefox, Opera, Konqueror ... Please help! (STEP-BY-STEP)

I suspect that you have used yast for an adsl connection (this is just if you have an adsl card in your p/c)- as you use a adsl router (I assume) go back into yast and delete these settings. The settings that you need to use are the network connection. This should pretty much sort itself out - just make sure that dhcp is shown
