Has anyone else had wifi issues with their iPhone 7 Plus? Mine is AT&T, 128GB. It is connected and never shows a drop in bars, but sometimes apps take 20-30 seconds to fetch data. Even using the app store, it takes a long time to use the search function to find apps. So far its only when I connect to my 5Ghz signal and not the 2.4Ghz setup. It was preset on version 10.0 out of the box, on 10.0.1 after I upgraded, and even now on 10.1 beta. I set it up as new, only logging in to iCloud to get contacts and other synced information. I did not restore from any back up. I've reset network settings and then tried reset all settings. I did a speed test and my ping was over 900 from a local server and the downspeed went from 0.05 Mbps to 24 and then back down to less than 1. The upload would spike more frequently between .05 and 12 Mbps. I tried resetting my modem as well, nothing has fixed the issue so far with my 5Ghz wifi connection. Only my phone is afflicted with this. My iPhone 6 Plus has no issues and my wife's iPhone 7 Plus just arrived today and she hasn't noticed any connection issues.
