iOS 15.4.1 Wi Fi problem

Called apple regarding this they had me run some troubleshooting. They couldn’t help over the phone and arranged an appointment in store. We went into an apple shop - the Genius Bar again ran some diagnostic, removed everything off my phone and reinstalled the new iOS. They deemed that I had been sent a faulty phone from insurance so had to go back to them. They were however, aware of this issue with the new iOS

Have you read any of the advice on how to fix it that have been posted in this thread that you just added to?

FIRST: Delete any VPN profiles on the phone (you can reinstall them later)

SECOND: Turn off Private Address of FIRST doesn’t solve the problem

Have you restarted your router?

have you deleted your VPN app and profile if you have one?

Have you tried removing any VPN app and profiles you have, as suggested several times in this thread by users who said it fixed their problem?

Thank you. Deleting the VPN app immediately restored the wifi icon on my phone and surfing is restored.

I trawled through google and YouTube with the same wifi problem after updating to 15.4.1, tried a dozen things nothing worked until I deleted my VPN app. Bingo! Wifi came back on immediately.

Removing VPN app (Tunnel Bear) fixed the problem for me (iPhone 11, iOS 15.5)

If you use VPN that is almost certainly the cause. After any update VPN may need to be deleted and reinstalled because it’s “fingers” in the protocol stack may have moved. And your router may need to be restarted after an update because the phone’s “lease” has become void and needs to be re-established.

If neither of those steps fix it post back for other things to check.

BTW, there is nothing for Apple to “fix” - hundreds of millions of phones that have been updated do not have this problem. It is a problem with your phone; if you want Apple to fix the problem with your phone take it to a genius bar.

And also, Apple does not read this user to user forum for imperious demands from users. That’s what the Get Support link is for.

Settings - Privacy - Location services - System services - Toggle OFF Wi-Fi networking (ON if it’s already off)

Reg intermittent connection, Can you try this and let know if it works.

Have you tried deleting your VPN?

No VPN

I’m sorry to say that this is not a “help desk”. It is a user-to-user forum where users try to help other users. I have 4 devices on 15.4.1. All of them still show full Wi-Fi speeds of over 100 mbps, matching my contracted cable speed spec. So if it is a problem with a version it is a VERY selective problem.

if you would like to discuss it with Apple (and also add to their problem database) click on the get support link at the top of this page. The only way Apple will know that it is a widespread problem (if it is) comes from users contacting Apple about it.

As a simple check of whether it is a phone problem or a network problem, test the phone on another network, like Starbucks or a Apple store. Have you done that?

Please restart the router. It should be done regularly, anyway.

Go Settings/Wi-Fi and tap on the i next to the network name and make sure auto-join is on.
