Setting up two wireless routers with a switch

I am trying to use a Netgear switch to set up two wireless routers at home, one a Linksys G and one a Microsoft b. I have used 192.168.0.1 for the Linksys and 192.168.2.1 for the Microsoft Router, channels 11 and 1, respectively, different SSIDs and security keys, and enabled automatic DHCP on both. Not sure if the Netgear switch has an IP that is causing a problem. The Linksys router is working but the Microsoft is not. My wife was having VPN disconnect issues with the new Linksys so she asked for the old router back where there were no problems.

Help appreciated.
