Apple has been mired in problems ever since iOS 8 (and the now infamous iOS 8.0.1 update). Quite a lot of iPhone and iPad users have been talking about Wi-Fi issues ever since upgrading/updating to iOS 8/iOS 8.0.x respectively. It's not the first time people are running into Wifi issues. And every time this happens, it's very crippling for users who rely on Wi-Fi.
If you've upgraded to iOS 8 (and possibly updated to iOS 8.0.2) and are still facing issues with Wifi, it's not entirely possible that you're stuck in this zone. You can try to fix Wi-Fi issues on your iPhone or iPad by following some of these suggestions. Dive right in:
How to Fix Wi-Fi Issues In iOS 8 (and Later) on your iPhone/iPad
#1. Wi-Fi Channels on Router
When your iPhone tries to connect to a router/Wi-Fi source, the strength of the signal decides how strong the connection is, how fast it works on your iPhone and most importantly, how it holds. You might have observed that on some weak signaled connections, iPhone will drop the Wifi when you let it sleep for a while. And when you unlock the iPhone, it might take a while to reconnect.
If your iPhone shows any of these symptoms, you might try changing Wi-Fi channels on your router (more on how to do this later):
- Pathetically slow Wifi or
- Disconnects from the Wi-Fi networks or
- Does not show the Wifi signal at all
Your Wi-Fi router can broadcast Wifi in different channels (1-8). You can try changing the Wi-Fi channel from your router settings to see if it fixes Wifi issues on your iPhone. The idea is to broadcast the signal in a channel that’s not congested.
To change the channel on a router, you will have to refer to the manual that came with it (or call router's customer support [not Apple]). In most cases, you should be able to get to the router settings by visiting http://192.168.0.1 in your browser (and entering the credentials for the router).
#2. Reset Network Settings
If changing the channels doesn't work (or if you can’t change them for some reason), one of the first things you can try is resetting the network.
- Open Settings
- Tap on Wi-Fi
- Tap on the blue “i” icon on the network that you’re connected to
- Now, tap on Forget Network
- After this, it is recommended that you reboot your iPhone (or at least a hard-reset to clear cache and stuff.)
- Head back to Wifi and select the network again. (Enter password to connect.)
Reset Network Settings
A total network reset achieves the same result (and more).
- Open Settings
- Tap on General, then on Reset
- Next, tap on Reset Network Settings
The iDevice will reset all network settings and do a quick reboot. Connect to the Wi-Fi again and see if things pan out well this time.
#3. Background App Refresh, iCloud Drive
Another thing overlooked by a lot of us is that iOS 8 is new and things like Background app refresh can impact Wifi performance. This is true when you are using apps that make use of your Wi-Fi even when they’re not being ‘used’. You can turn off Background app refresh for apps that you don't want to be using the feature.
The other service that could be using Wifi silently is iCloud. If apps are connecting to iCloud/iCloud Drive in the background and trying to upload/download files from it (through Wi-Fi), there’s a strong chance that you could experience intermittent bouts of slow/unresponsive Wifi. Fixing this means you might have to turn off iCloud Drive or limit it by disabling apps from using iCloud/Drive for sometime.
#4. Fresh Install (IPSW)
As a last resort, you should try to re-install iOS 8 (or in this case, iOS 8.0.2) on your iPhone/iPad. But this time, don’t let iTunes fetch the iOS 8(.0.x) file. Download the “IPSW” file yourself (from here; make sure you get the right file for your device) and do a Shift+Restore (Option+Restore in Mac) through iTunes.
When you press Shift(Win)/Option(Mac) and then click on the Restore button in iTunes, you get to pick the downloaded ipsw file. From here on, iTunes takes care of the restore. (Make sure you backup before you do all this).
