I recently purchased a Samsung Note 7 and have been having the most peculiar issue with connectivity. I didn’t do any in-store setup, except the basic prompts and to make a phone call.
I am currently in a rural area with marginal (1 bar) of AT&T 4G. When I got home and started doing the phone setup, I noticed a very odd problem. Using the Note connected to WiFi on my Surf SOHO (which is connected to a Verizon hotspot), I was unable to get sign-ins working for Google. I kept getting connectivity warnings. “Can’t connect to server, try later”. Google Play Store - Connection timed out. However, I was able to surf the internet in Chrome, run a speedtest app, etc. Tried in airplane mode, and even with the SIM removed. Numerous factory resets, etc. Deleted data/cache for Play Store app. No dice.
At the same location, my other phone (S6 Active) is not having the same problem. Nor is my iPhone 6S Plus. Nor is any other device in my possession. Wen I am closer to town with LTE coverage, the phone works fine. Same story when it’s connected to other WiFi hotspots (including directly to my Verizon hotspot).
The AP is set at 802.11na. I can’t imagine what is causing this problem, but I seem to have ruled out everything except the router.
Posting this here in case anyone has seen this behavior. I did also create a support ticket.
