Device pair for IPTV over WiFi

Hi, maybe I am completely wrong but I guess I could ask. I am thinking about getting IPTV (double play) over my still new VDSL Telekom line. I will have to connect the box to LAN4 output. Problem is I do not want to grind holes in the walls and lay cables and all that stuff. Instead I was thinking about using pair of 5GHz cheap devices (configured as AP and Client thus emulating cable connection) as there are plenty of free channels in that band. So is this plausible thinking and are there any cheap devices that you would recommend?
