  • Software Bugs: One of the most common reasons behind iOS 17 wifi issues is the software bugs. Sometimes, certain glitches or errors can occur during the update, which can cause disruptions in the wifi. These bugs cause some serious connectivity problems like slow speed or complete wifi disconnection.
  • Broadcasting All 20/40/80/160Hz Ranges: Since the iOS 17 update, iPhone users have been sharing their problems online. During a discussion, a user reported that broadcasting 20/40/80/160hz ranges simultaneously could be causing the problem. This can cause connectivity problems, low signal strength, and instability in the network connection.
  • Interrupted Wifi Settings: Interruptions in your wifi can also be a reason why your iPhone is not connecting properly.
  • Unstable Wifi Connection: Moreover, an unstable Wi-Fi connection can also be a cause of the Wi-Fi issues experienced on iPhone 15 after upgrading to iOS 17.

Ever since the iOS 17 update, iPhone users - particularly the ones with iPhone 15 - have been reporting wifi issues. Now that you know the possible reasons behind your iOS 17/iPhone 15 wifi issues, you can better understand what to do to solve the problem.
Let’s look at the 5 most common wifi problems in iOS 17 and what to do to fix them.

Top 1: Wi-Fi Cannot Stay Connected

If your Wi-Fi connection keeps dropping, you can try the following fixes.

  • Method 1: Restart your iPhone and router. This can often fix minor software glitches.

  • Method 3: Forget and reconnect to the Wi-Fi network: Go to Settings > Wi-Fi, tap the "i" icon next to the network you're having trouble with, and then tap "Forget This Network." Then, reconnect to the network by entering the password.
  • Method 4: Reset your network settings: To reset your network setting, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. However, this should be your last resort because your data is at risk when you reset your network settings.

Top 2: Unusual Slowness When Connected Wi-Fi

Try these fixes if your wifi is working at a snail’s pace.

  • Way 1: Restart your router: This will refresh the connection and might as well solve the minor issues with your connection.
  • Way 2: Move closer to the router: The farther away you are from the router, the weaker the signal will be.
  • Way 3: Turn Airplane Mode on and off: Turn on the Airplane Mode and turn it off. Then try reconnecting with the wifi network.
  • Way 4: Clear cache data: Clearing cache data can help speed up your connection.
  • Way 5: Disable VPN: If you're using a VPN or proxy, try disabling them temporarily to see if they are impacting your Wi-Fi performance.

Top 3: No Networks Detected

If your iPhone fails to detect any available network, these solutions might work for you.

  • Tip 1: Make sure that Wi-Fi is turned on: To make sure your wifi is turned on, go to Settings > Wi-Fi and see if the toggle switch is on.
  • Tip 2: Restart your iPhone: Again, restarting your iPhone might help with issues like this.
