Currently have a wired router for a pc, a tv and various gaming consoles. All are hooked up by ethernet cables. The PC and tv are hooked up directly from the wired router. The gaming consoles are run by a single ethernet cable hooked up to a switch port that connects to 3 gaming systems in another room. Want to have a wireless connection for a laptop that is near the switch port. Can a wireless router be used at the switch box? If so, how? Any other suggestions for a wirleless connection? Also, the wireless is just for the laptop and want to be able to use the laptop at the same time as the other wired connections are being used. Thank you for your help.
