iOS 17 bug: Wi-Fi not connecting after restart iPhone and iPad.

After iOS 17 update when I close the device, and then open it again, does not connect automatically with my Wi-Fi. I have to get in the settings and then close and open the Wi-Fi so it connects.


This is happening to all our family devices. iPhone 13, iPhone 14 plus, iPad mini, iPad Pro M2.

iPhone 14 Plus, iOS 17

Finally figured it out. Dang, was starting to look at android phones. If you have done all the routine things and still no help, see if you have the google one app. Delete it. Even if you have VPN turned off, doesn’t matter. Doesn’t matter that it all worked fine before the 17 update. I did everything including a complete restore of my phone, but since other iphones in the home with the same ios update did not have the problem, I figured it was some combination of the update and an app. I knew there was talk of von software causing an issue and I had this turned off. Didn’t matter. As soon as I deleted the google one app, wifi auto join and password entry was automatic once again. I am sure apple knows this but probably doesn’t care so much since it is a google *** incompatibility with the new upgrade, but son of a … Not a fun time figuring that out. Really odd that despite turned off in the main settings it was preventing my auto wifi recognition. I’d would think that worth looking at any VPN app as a possible suspect. Hope this helps anyone in this same situation.

Well, no, not necessarily. As a software engineer (and just as a user), I can say that it is frequently the case that a bug can affect a smaller number of people because some issues are often only triggered by a very specific set of circumstances, sometimes rare or sometimes under a specific unlucky timing situation.


However, in this case it looks like enough people are being affected that fixes for WiFi issues are already coming with iOS 17.2:

Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.

  1. Restart the device. That's it.
  2. Still not solved --> Force restart iPhone - Apple Support



Reset Network Settings: Only network settings are removed.

  • When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
  • To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
  • To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
  • Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.


If the above fails...



Reset All Settings: All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.

  1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
  2. You can return settings to their defaults without erasing your content.
  3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.



If nothing above works probably it could be your iPhone may have a WiFi radio or antenna problem. In that case, take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support and get the hardware tested and if needed repaired/replaced.

WI-FI connection in settings, IP address configuration change automatic to manual and copy the IP address if possible save it/ or chose BootP (what is super old solution however works) - for me this solved issue at the moment! (iPhone Wi-Fi settings Configurate IP: change automatic to BootP) and voila works, but this definitely IOS software issue (Bug) and looks like not affect every router but some of them yes. Hopefully IOS 17.1.2 solve this issue.
