Kind of at wits end on what else to try on my Note 3. Hoping someone else might have some ideas. Support just seems to think doing factory resets to the phone every day is the way to fix my issue, which A) Doesn't work and B) isn't very practical.
My issues started with the Note 3 dropping wifi connections constantly in our house. We don't really believe it to be a router/AP issue as I have a mytouch slide in the house and an iphone 5s using the same Wifi with no issues at all.
After some investigation on my own, I have found that if I set up the WPA2 security on my AP to only use AES encryption (no TKIP), my internet wifi connection on the note 3 became much more stable. Wifi calling outbound became better, but I still experience intermittent drops. On the inbound side, I no longer have the 1:25 drop, but like outbound I have intermittent drops. My son, on his mytouch slide never drops a call, even when he is working from home. His calls last for hours.
I have the same issue in several wifi locations outside my home, including 3 or 4 airports and several different hotel chains (Marriott, Hilton, etc). Forget about using wifi on Southwest airlines or Delta, the connection terminates within 5-30 seconds of connecting to their networks.
I've turned off the auto-scanning and several other options based on research I have done on the web, but still no joy. Discussions with Samsung only leads to a "it's your carrier" conclusion.
I'm not sure who actually supplies the wifi software, although I would think it would be either a Samsung firmware/Android driver issue based on the constant renewal of the "Calls will be made over Wi-Fi" messages that pop up at the top of the screen. I think this is a symptom that shows the wifi connection is actually dropping and reconnecting even when no calls/internet connectivity is occurring (at least any communication that I knowingly initiate).
Overall, I love the phone, but I really need to get this issue fixed. I am hoping someone has received a resolution from T-Mobile/Samsung that just hasn't been shared as of yet.
Thanks for reading.
