IOS 8 Bug: Wi-Fi slow and dropping signal

A lot of people have experienced a Wi-Fi problem after updating devices to iOS 8. The Wi-Fi signal will appear to be strong, but websites are slow to load and video slow to buffer. In some cases the connection seems to drop altogether, and in other cases it just slows to a crawl. You may get a message that “the server has stopped responding” if you’re trying to use Safari. Other devices are still able to connect to the router and enjoy the usual speeds.

Workarounds:

  • Toggle Wi-Fi/Airplane mode: You might find that it comes back temporarily if you toggle Wi-Fi off and then on again. Alternatively you could switch on Airplane modeand then turn it off again. Swipe up from the bottom to open the Control Center and toggle these settings.
  • Reboot: Some people report temporary success by switching the device off on and again. Press and hold the Sleep/Wake button and the Home button for ten seconds or so, until you see the Apple logo. Your Wi-Fi may work again for a while.
  • Turn Bluetooth off: Sometimes Bluetooth can interfere with Wi-Fi speeds so you could try turning Bluetooth off. It won’t fix the issue, but it might reduce it.

Potential solutions:

  • Reset Network Settings: Try going to Settings > General > Reset and tap Reset Network Settings. This has worked for a few people, but the problem might return.
  • Turn off Wi-Fi Networking: Try going to Settings > Privacy > Location Services and under System Services you need to toggle off Wi-Fi Networking.
  • Toggle 2.4/5GHz: If you have a two channel router then try changing from 5GHz to 2.4GHz. Generally speaking 5GHz is faster, but with a shorter range. Some people report a better connection on 2.4GHz and a few find an improvement by switching the other way.
  • Change router channel: You could also try changing the channel on your router. You’ll need to put your router’s IP into your browser and log in to change settings. Refer to your ISP for instructions.
  • Switch DNS to Google: Some people report success after switching DNS to use Google servers. You can do this via Settings > Wi-Fi then tap the ”i” icon next to your router, scroll down to DNS and tap the numbers, then enter “8.8.8.8”. You might have to restart your device for this to take effect.
  • Factory Reset: It’s a drastic step with no guarantee of success, but you could try a factory reset. Here’s how to factory reset an iPhone.
  • Update probably coming: There’s clearly some kind of glitch in here, so Apple is very likely to release a patch to deal with it. Keep an eye on Settings > General >Software Update.
