Any issues anybody knows of with wireless? or anything else re: interference for TV etc
There will be more deadspots then wood framed I would expect too, but considering that a single AP has trouble covering a wood framed house unless its the size of a 3 car garage virtually, I would just do what is prudant in any house and install multiple accesspoints where you will need the best signal.
You need a better access point if it doesnt cover your house. Mine easily covers our 5 bedroom house end to end, side to side.
