"How to use a router as a WAP."
It's a more common setup without the headaches cascading routers create.
Okay, I know this may sound similar to one of my previous post, but this is a different problem. I have a Netgear router connected to a cable modem. Connected to the Netgear is an old Belkin with all its wireless turned off. What I want is for my Belkin to expose its computers on a secondary subnet. What I mean by this is that say my netgear runs on 192.168.1.x and my Belkin runs on 192.168.2.x. I want 192.168.1.x computers to be able to directly access 192.168.2.x computers (*cough* Ubuntu Domain controller *cough*) but have the Belkin using its own DHCP and such. Does anybody know how to do this? Feel free to ask for clarification
