Room A (bedroom) = ISP Router/4 port switch/WAP. Too far away and/or too many walls to be used by the Roku (wirelessly).
Main TV Room = No previous CAT5 wiring. That is where the new WAP was installed. It's a D-LINK DW-G700AP, with the CAT5 ran back to Room A and plugged into the router.
Without seeing the room and it's weird attic/no attic configuration; suffice it to say that the closest I could get to the TV (from within the house) is the opposing wall about 15 feet back. That is where I ran the new CAT5 and have the WAP.
In order to get a hard wire to the TV position (without opening up the inside walls) is to come out of the attic and externally run a CAT5 for for the 15' and enter the wall behind the TV.
The 15' between the TV and the opposing wall has no attic. It's a 12' high pitched roof that was added on to the existing house back in 1987. The opposing wall is where the attic ends.
