What you should try is putting an ethernet cable in between a LAN port of your cable router and a LAN port of your wireless router, not the WAN port. Then, on the wireless router, change the operating mode to gateway (not router), so all information will simply pass right through the wireless router. And make the wireless router's IP address in the same subnet. Then, I believe you should set the gateway IP for all the wireless computers to the IP address of the cable router, and that should do it.
Let us know if you have more issues or if this doesn't work.
