[Solved] Wifi disconnects randomly - iOS 10.2.1

[nandosk8]

Hello friends,

I have an iphone 7 Plus that was with iOS 10.1.1 installed, everything working perfectly. But then I saw that iOS 10.2.1 was released, and whenever a "big" update is released (10.1 to 10.2), I restore through iTunes and set it up as new (without getting backup). From there I started my problem, in iOS 10.2.1, now the wifi disconnects randomly, and I can not even download a large file from the App Store (some games with more than 400 MB). What I tried to do:

- settings -> general -> reset -> reset network settings
- restarted iphone
- disabled / enabled airplane mode
- disabled background app refresh

I tried 2 different wifi networks (at home and at company). At home, it is working just fine, but at company, the problem persists. I have never had this problem in wifi's company!! Everything started when I updated to iOS 10.2.1....

Is someone having this problem too?

Same phone, different networks = probably your router at company is having problem. If you can't restart router at company you should try do get IT support that is responsable for company network and say to them to restart network.

Yeah, my wifi at the university will disconnect if I'm not using it. (But never while I'm using it...)

I have restored iOS 10.2.1 AGAIN from settings -> erase all content and settings, without getting backup. Iphone is a little better, it disconnected just once... and I have restarted router at company as well. I hope this fix it!! I will be watching...

flawless wifi here on all ios devices, mind u we are using decent quality hardware with a generally good firmware, ddwrt on our routers.

routers & their firmware cause most problems (assuming user knows how to properly setup its settings)

I have searched for people who had the same issue, and I have found some in:
https://discussions.apple.com/.

I mean, all problem started after iOS 10.2.1 update... I'll just wait for a fix (sadly...)

SOLVED!!
At company, I just disabled WMM (Wifi Multimedia) and now my iphone 7 plus + iOS 10.2.1 has not disconnected at all !!! PS: at home, my router has WMM enabled and doesn't disconnect... so strange.
