WIFI not working iOS 17.1.2 IPhone X

It has to be the update. I have been having the same issue with both my Iphone and my Ipod. My aunt said her and her boyfriend have been having the same problems with theirs too. All of us have had no issues connected to our Wifi on other computers or laptops. Its only been on our Apple products.I have done all the steps except factory resetting my phone, which I am not going to do and shouldn't have to do. Apple needs to fix this issue ASAP.

Having the same issue.

iphone 13 pro max at 17.1.2.

running speed tests off of wifi and they are slow.

I have a 13 pro and it’s at 16.6.1

no problems.

ran speed test from other devices. No problems. PCs. TVs. All connected on same WiFi.

definitely not routers or wifi. It’s the update of 17.1.2.

iPhone 15pro: same problem, working after turning VPN off. NordVpn

If you need help with your Wi‑Fi password – Apple Support (UK)

•  You need to sign in to your router.
• The Wi-Fi network name, or SSID (service set identifier), is the name your network that has a password.

or If you have iOS 16 / iPadOS 16:

Go to -> Settings -> tap Wi-Fi -> tap on the hidden Password -> enter Passcode -> you will then see the Wi-Fi Password.

If they are On, turn Off Hotspot & VPN.

FWIW For me it was VPN related - my ex-phone carrier (Google Fi) provided VPN configurations onto the phone, and after I switched off to another carrier it kept messing up with looping "VPN Connecting". After I have deleted all VPN configurations from my phone - it seems to keep the WIFI connection on (and not using cellular data as before).

iOS updates generally aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. WiFi issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

This seems purely coincidental so please check the Setting on your device. Internet not Connected but WiFi enabled - Apple Community

I understand your frustration because I’m in the same position. My IPhone 11Pro Max been activated just 2 days before this happened. The phone switched off automatically and switched back ON without being able to use headphones/wifi. There is a simple strategy which I believe is true. I’ve talked with them over the phone and they try “hard” to help me but they said the only solution is to go to Apple Store. Which means they want us to go to Apple Store to have a better experience using the new devices in order to get attached and buy it. I don’t have nothing to complain about Apple devices as I’m a satisfied customer since 2010 and there was nothing to complain major. But this time they will not lose customers/ they will bring more customers then you think. Well done to you guys. (Just sort out my IOS please) as I’m not buying a new one atm.
