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

Every since I updated my phone to 17.1, the phone won't connect to our WiFi router. I have tried all of the troubleshooting steps including disabling and then reenbling WiFi on the iPhone, power cycling the phone, power cyling the WiFi router, trying different encryption (WPA2 and WPA3), and moving to 2.4 GHz radio, then back to 5 GHz radio band, and some other changes on our WiFi router, but nothing works.

Also, ever since I upgraded our iPad to iOS 16.7.1, the iPad has also not been able to connect to our WiFi router.

Finally, a family member updated their iPhone to the most recent iOS, and now their iPhone can't connect to WiFi.

Apple, please fix this bug ASAP.

I assure you, it’s not a problem with the WiFi. I updated one iPad and my iPhone 12 to IOS17. They no longer connect to the internet… immediately after the update completed. My other iPhone SE and IPad that I did not upgrade connect to the Internet perfectly… as before. It’s an IOS17 glitch. And I further assure you that this IS most certainly affecting many, many iPhone and iPad users.

I came across this thread while looking for answers to a similar but different behavior since upgrading my iPhone 14 Pro to iOS 17.1 this week. (I waited until 17.1 to move from iOS 16.)

My iPhone continues to connect automatically to my home WiFi network but it stops actually working, usually overnight. All network activity then fails and times out while WiFi continues to work fine on all other devices. It takes some sequence of disabling/re-enabling WiFi on my phone (with/without airplane mode) to get it working again. A reboot also fixes it for a while. I had no trouble like this until iOS 17.

Just offering this as an FYI. Now I’ll continue looking to see if others are encountering this…

After I updated my 12 pro max to the new iOS 17.1 my wifi stopped working. I have tried networking reset and also other method still not working even my hotspot isn't working.

The fellow who says it is not related to the update needs to reconsider his deductive abilities. Of course it is the update. It is just not affecting everyone, because not everyone has all the same apps and setups on their phone. This is what we call a glitch in the programs g world and an unintended consequence. There is some setup that is particular or some other app or network or whatever that has caused the issue with some but not all iphones. Regardless, apple needs to find the problem - incompatibility that has come up because of the update. I am sure that hundreds of thousands of people are having the problem and many may not have realized it or they just don’t go to this forum. It is rampant on the internet.

That is so sad and frustrating!! I have the same issue, I updated my iphone 13 pro max to ios 17 around November and since then I cannot connect properly to any wifi and bluetooth. I tried EVERYTHING even factory reset my phone but still unsuccessful! What do they mean my liars? Don’t they read these threads? I tried updating my phone hoping the next update will solve it but NO, til now ive been using data 😭, I did not even try to update my ipad cuz im afraid it will have the same issue..

APPLE TAKE ACTION!!!

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 con 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.

Yes - me too and nothing fixes it. All the helpful tips in the world will not fix this. I have reset my network. Reset all the setting on my phone, and of course the auto join is on - duh. Ever since went to 17 now essentially not useful. Going to try an android now after having every iphone they make!

iPhone was just updated to 17.1.1. On restart, it did not connect to my home wifi network, which I can confirm is up and running properly. It was using cellular data until I turned its wifi off and on again (and I got an alert about my cellular data being almost exhausted while I was doing this).

This bug is now actively costing me money.

I’m having the same problem but nothing is fixing mine and I’m getting very stressed out I have class online tomorrow and if I can’t get on WiFi I can’t do my work

It is related to the iOS 17.1 update.

Once I updated my phone to 17.1, the phone won't connect to our WiFi router. I have tried all of the troubleshooting steps including disabling and then reenbling WiFi on the iPhone, power cycling the phone, power cyling the WiFi router, trying different encryption (WPA2 and WPA3), and moving to 2.4 GHz radio, then back to 5 GHz radio band, and some other changes on our WiFi router, but nothing works.

Also, ever since I upgraded our iPad to iOS 16.7.1, the iPad has also not been able to connect to our WiFi router.

Finally, a family member updated their iPhone to the most recent iOS, and now their iPhone can't connect to WiFi.

Apple, please fix this bug ASAP.

Can confirm this happens on multiple devices, both an iPhone and an iPad upgraded to iOS 17. On restart, WiFi simply fails to connect until it is manually disabled and re-enabled. It's specific to iOS 17, because an iPhone which still has iOS 16 does connect automatically to the same WiFi network on restart. And on the iOS 17 devices, this behavior only began after the devices were upgraded from iOS 16.

In fact, the Control Center will show the name of the network that the iPhone or iPad is trying to connect to, reading as though it's connected, but without a signal strength indicator where the WiFi signal strength should normally be, until WiFi is manually toggled off and on again. This is especially annoying for an iPhone that restarts overnight on its own, fails to connect to WiFi, and chews into cellular data allotment during the night.

This is a bug. Solution: change conf. iP to manual (IP address/subnet mask/router) as well as change conf. DNS to manual.

Gee dude, I guess it is impacting others.

since 17.2 is planned to fix WiFi issues.

and now broke WiFi CALLING.

Apple smh.
