I was hoping someone could help me with a problem I am having. I just bought Apple TV 3rd gen and it all seems pretty good until I try and extend the monitor using Airplay to stream. The video is laggy and stutters. Its ok when I play content directly from ITunes and when I use Beamer, however I also use XBMC and want to stream it to my TV downstairs. I tried a few things and it did seem to fix it but it isnt a usable fix. I did the following In the display preferences I set it up to best match the Apple TV I changed the ATV internet connection from WIFI to Ethernet as the router is next to the ATV I tested it stream after I changed the above settings and it was still stuttering. I then went into my router settings and change the band from 2.4 to 5 and tried it again. The stuttering stopped and it works great ..HOWEVER, my Wi-Fi signal on my mobile phone is now terrible despite changing the band on it to also use 5. Does anyone have any suggestions on how I can sustain this fix so that my other Wi-Fi devices wont suffer? Cheers!
