iOS 9 – iOS 9.3.1 come with ton of new features and improvements, but sadly, likely any other major iOS software update, it comes with its own sets of problems.
One of the issues people are facing after updating their iPhone or iPad to iOS 9 – iOS 9.3.1 is Wi-Fi connectivity problems.
The issues being reported include not being able to connect to a Wi-Fi network, getting incorrect password prompt, Wi-Fi settings grayed out, dropping connection intermittently or speeds being extremely slow.
Here are a few tips to fix these Wi-Fi problems with iOS 9 – iOS 9.3.1:
Like all tech problems, there is not harm in starting off by force restarting your iPhone or iPad to see it helps.
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the screen goes blank and Apple logo appears.
Forget Wi-Fi Network and Rejoin
If you’re not able to connect to a Wi-Fi Network, and being prompted that the password you’ve entered is incorrect despite entering the correct password, then try to forget the Wi-Fi network, and join the network again.
To forget the Wi-Fi network, tap on the Wi-Fi network from the list under Settings > Wi-Fi. Then tap on Forget This Network. You will be prompted with a popup message asking you if you want to forget Wi-Fi Network. Tap Forget to forget the network.
Now go back to Settings > Wi-Fi, select the network again, enter the password, and Join the network again to see if it helps.
Disable Wi-Fi Networking Services
Many users have reported that they’ve solved their issues by disabling Wi-Fi Networking under Settings > Privacy > Location Services > System Services. This only relates to your location being used for Wi-Fi Networking, so it doesn’t disable Wi-Fi entirely.
Reset Network Settings
Most networking related issues I’ve experienced have been fixed after resetting network settings. Resetting these settings flushes caches and clears DHCP settings and other networking related info. To reset network settings, open the Settings app and navigate to Settings > General > Reset and tap on Reset Network Settings.
