Solutions:
Here are a few tips to fix these WiFi problems on iOS10.
* Force Restart
Hold down the Power button and the Home button at the same time for at least ten seconds, until the screen goes blank and Apple logo appears.
* Forget WiFi Network and rejoin

To forget the Wi-Fi network, tap on the WiFi network from the list under Settings→WLAN. Then click Forget This Network. You will be prompted with a message asking you if you want to forget Wi-Fi Network. Click Forget.
Now go back to Settings→WLAN, select the network again, enter the password, and Join the network again to see if it helps.
