Wifi disconnects randomly - iOS 10.2.1

[iMore Question]

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
- restarted router
- 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?

I would talk to the IT department at the office to see what they are seeing on the WiFi router logs. You will see the drops there and it should tell you why its dropping.

That is a start. We have that issue in our office and it is the auto negotiating between access points that is causing the drops.
