It could help. Here I installed Open Suse 10.0 and the one question that made it "just go" without any work was during install to use DHCP.
If I hadn't done that I could have used it's control panels to fill in the numbers. Since your linux is unknown, you can try manually assigning the numbers.
getting my linksys befsr41 cable/dsl router to work with linux for some reason when i go to select DHCP it is grayed out
can somone give me a clue here?
i would really like to get online
