I run wifi to my 43Nano via a NetGear Nightranger 2 band extender with no issues. Extender is about 8 ft. from the set. I recently purchases (2) 24" LG sets, both also about 8 ft. from the extemder, but neither of them can handle an HD stream (720 or higher) without constant buffering, as in they are unwatchable in HD, even if only one of them is the only demand placed on the extender. The extender is clocking 75 mbps and the 24" sets are clocking only about 10 mbps, far lower than the 43NANO. Do the 24" sets just have inferior wifi chips, or what? I have followed many recommendations on optimizing settings, but nothing works. All sets are logged onto the 5ghz band. I'm trying to avoid having to set up ethernet connections. Any thoughts?
