re: Which router setup use should I use? Turn wireless router off & use as a switch

BTW, I forgot to add, the correct way to hook it up is to use the WAN(Internet) port on the router in the office to connect to the internet and the switch ports to connect to your PC, Printer, XBox and the last one run to the middle of the house router.

Then at that router, ignore the WAN(Internet) port and connect into one of the switch ports. Then that router will just act like an access point.

You could actually leave wireless on on both devices and just connect to the one you had a stronger signal.
