Gotta be a problem with login, workgroup name or protocol I don't quite understand that either. I followed the instruction I got from internet. I set one folder to be shared and give a user privilege to it (with a password) on each PC, but I cannot see my other PC on either PC. With MacLan on PC, I can share files between Mac and PC with the hub setup, but not PC to PC. Without changing an settings, 2 PCs can see each other right after getting connected with the router. I'd like to know if you know the reason, or what setting to change for it to happen. I don't know if it's related to the fact that gateway is a road runner address. Since I'm part of the big cable network. They might block the usual pear-to-pear network so it's harder to get hacked??? There should be a way but I never called their tech support to find out.
