How to solve Wi-Fi issues in iOS 10
With every major iOS update macOS or even some users are experiencing serious problems. iOS 10 in this sense was no exception. Many users began to complain about the problem in the Wi-Fi network. There are several ways to solve the problem.
Rebooting the router
Sounds simple enough, but sometimes the problem is not in the mobile device and not iOS. To start is make sure the router is working properly.
Hard reset on iOS device
If restarting the router did not help, the next logical solution is to perform a “hard” reset of the iPhone or iPad. For this you need to hold the Power button and Home (or the volume button on the iPhone 7) for 10-15 seconds until the Apple logo appears.
Re-connect to a Wi-Fi network
Unstable Wi-Fi connection doesn’t always mean hardware or software failure, sometimes it could be just a glitch specific connection to a specific network. In order to fix it, go to settings, wifi and click on the “i” icon next to the desired Wi-Fi network and select “Forget this network”. Now try to reconnect to the network.
Reset network settings
In many cases it helps to reset the network settings. Go to Settings -> General -> Reset -> Reset network settings. This procedure does not affect user data, but removes all network connections.
“Using Wi-Fi” is quite interesting and relatively new feature in iOS. It is not unique to iOS 10, but has an impact on the Wi-Fi. The meaning of the function Using Wi-Fi” is the ability to compare bandwidth Internet connection over Wi-Fi and mobile network. In that case, if the wireless network is not stable and quickly, the mobile device is able to switch to using mobile Internet – 3G or LTE. To disable, go to Settings -> Cellular.
Disabling location services for Wi-Fi
Another feature that directly affects the Wi-Fi connection. In order to disable location services for Wi-Fi networks, go to Settings -> Privacy -> location Services -> System services, use the slider to disable the location services for Wi-Fi network and reboot your device.
A “clean” install of iOS 10
If none of the above helped the time to pass to more radical methods. For so called “clean” installation, you need to update iTunes for Mac or Windows to the latest version and download the IPSW file of iOS for the device 10.
Now turn off “Find my iPhone” in Settings-> iCloud -> Find my iPhone. Connect your iOS device to your computer and select it in iTunes. Alt on Mac or Shift on Windows, click the “Recover” option and specify the path to the downloaded IPSW-file.
Wait for the device and restore your data from backup.
Rollback to iOS 9
Even if the iOS install 10 from scratch nothing changed, you may want to revert to the previous version of the OS.
To get started, download the IPSW file of iOS 9 for your device. Then turn off “Find my iPhone” in Settings-> iCloud -> Find my iPhone.
Connect your iOS device to your computer and put it into DFU mode. In iTunes Alt on Mac or Shift on Windows, click the “Recover” option and specify the path to the downloaded IPSW-file.
Do not disconnect the gadget from the computer until iTunes notifies about the successful completion.
