Need help joining network

view story

http://forums.opensuse.org – I installed Susse today and I am unable to join my home network. The network is called WORKGROUP and I don't even see it. The network has 2 Macs, 1 Ubuntu and 1 Susse. All the other computers are on the network and can share files. I also need access to the two printers on the other computers. Please help! I am connected via a Buffalo router via cat5.
