I am not sure exactly the technical hardware piece that I need or if it's possible but I thought I would ask as I have exhausted my searching abilities.
I have my playstation (wireless), sony tv (wired) and DirecTV box (wired) sitting in one area.
I have a wireless router in my hall closet (WRT160NL).
I have my computer and playstation connected to it using wireless.
My question is, is there a device I can put by my TV and DirecTV box that I can connect to using a network cable and have that device connect to my router using wireless.
