Quick question.... I may be buying a media device that needs to be hooked directly to a wireless router in order to stream video content across my home. Problem is, the device is in the adjoining room and cannot easily be hooked directly to the router. I can, however, run 50' of ethernet cable from one room to another (I already have a small hole in the wall between the two rooms). If I run 50' of ethernet cable, will there be a measurable loss in signal strength between the two devices? I'm sort of comparing this to the way you lose signal strength when using using long extensions of coax cable. Also, do I need a CAT5 or CAT6 cord? I have no idea the difference.
