Been noticing some odd behavior with my Note 4 since I got it on Saturday (I love it by the way). I cannot get it to get a stable connection with in-home WiFi, and when it does connect, data-heavy apps like the Play Store, Facebook, and Google Drive are rendered worthless and I stop receiving emails. Turn off WiFi, and everything is back to normal, running quick. Turn it on and the issues immediately start. Took the phone back to Best Buy thinking I had a bad WiFi antenna in the phone, and it immediately connected to their system and acted normal. OK, so its not the phone. Brought it back to the house, and, just for kicks to see if it was the router itself causing issues, flipped it out with a 3 year old Netgear router I had. This time, the Note wouldn't even connect. (mind you, my wife's Galaxy S5, my old Razr Maxx HD, my Nexus 7, and my work laptop are all functioning just fine with the router I have this entire time). So now I know it wasn't an issue with the routers I have. The guys in Best Buy told me that the new devices are using new WiFi technology and its very likely my Note 4 isn't compatible with the routers I have. Told me to perform an internal reset of the Router settings, and that didn't help at all. Any suggestions? I recently bought a Belkin AC1200 router, which Best Buy is still selling, which claims to be next generation wifi. Something just isn't adding up here.
