Question : Is it possible to have a Wired and Wireless network where the wired network is local only and the wireless provides internet access?

I have a wireless router serving up an internet connection to XP PRO and Vista Home Premium boxes.  Each computer has an ethernet and wireless card.  The physical location of the router is next to the cable output in a bedroom.  The computers are located in another room accross the apartment nowhere near a cable outlet so running a cat5 cable form the bedroom to the computer room is unfortunately out of the question.  

I noticed when running lan games that the wireless frequently looses connectivity for brief moments causing an annoying lag issue.

I have a second wired router that I would like to hard wire the computers to hopefully eliminating my lag issue.  However when I tried this, my internet connection on my XP box became very slow to connect (I assume it tried the faster wired connection first) and my Vista box lost internet connectivity.  

How can this be done so that internet comes in through the wireless and network calls move through the hardwired LAN?  

Wireless IP range 192.168.2.100-115
Wired IP Range 192.168.1.100-115

The wireless and wired networks need to use different subnets (not subnet masks). Both are using 192.168.2.x Try changing both wired adapters to 192.168.3.x (such as 192.168.3.80 and 92.168.3.81)
