Iphone 12 Pro Max Keeps Losing Wifi Signal

I have had the same issue with the iPhone 12 PRO. Today I did troubleshoot with Apple and they had me do a Network Reset and it appears to be performing well now.

Settings - General - Transfer or Reset iPhone - Reset

Once you do this you will have to renter the password for your wifi network.

Hope this helps you!

OK I phoned Apple Support and got a resolution for my issue which was to deactivate McAfee VPN

After weeks of annoyance and trying everything, I discovered it was my VPN settings. I have set them to turn off automatically when on my secure home network.

That finally solved the problem

We have both an iPhone 12 standard and a new iPad air both having the same issue on a Google nest wifi mesh system. Recently we travelled and stayed in a hotel where both devices had the same problem on the hotels wifi. I then took the iPad air to work where I connected to a Cisco wifi network- same issue. Slam dunk result and the issue is apples. My wife had an iPhone XS before this 12 which never had the issue. For the first time ever my wife wants to move to Android.

It's not. Had the issue as well after the 14.5 update. I've reopened my support ticket. Please, please contact apple support if you haven't already and demand an escalation. The software in an iPhone 12 Pro Max (and obviously other 12 models) is definitely not backwards compatible with a vast swathe of routers.

I already reset the network preferences, enabled 5G, etc. However, the only thing is solving the problem (since yesterday night) was disabling the Wi-Fi Calling. Somehow this worked this time, as I had already done that some time ago and it was not fixing anything.

WHAT TO DO? disable Wi-Fi Calling, on the "Mobile Data" menu; disable also "Location-Based suggestions" on "Location Services".

No idea if you need to disable both, but I did and it worked.

@APPLE it is now time for you to solve this ridiculous thing!!! A phone as expensive as this should not be putting its users to deal with things like this! Take responsibility for this.

For what it’s worth I read on the internet to reset the network setting. This could be found in settings. Up until then I haven’t lost signal. Would be 7-10 times daily before that. Seemed to have worked but it’s been only a day or two. Good lk

Me and my wife an iPhone 12 and a 12 pro max could not get on the internet at all. I have a eero 6 router it is upstairs in bedroom . I also have a Amazon fire stick down stairs that was running on Wi-Fi. I hard wired the fire stick and bought a eero booster for down stairs and the problem has gone away and no issues for past month.

Hope this helps

I have same issue. T-Mobile spent 4 months trouble shooting. Said its a Apple issue. Its on the 12 pro max! My wireless now quit altogether! Started just dropping like the post above. Then got worse. I am downloading the update but since wifi does not work its a major problem! How are you supposed to download updates when wifi drops and quits working? How are you supposed to backup iPhone to iCloud when wifi cuts out to send in iPhone to apple for fix? How are you supposed to backup iPhone to older mac without updating mac OS older mac processor does not support?

These are teal issues that need immediate attention. And a IOS update to rectify. Both T-Mobile and Verizon are aware of the issue and say to either update to newer iPhone or turn 5G off in cellular and set to LTE. The issue is real!

Had the same issue and discovered that my Avast SecureLine VPN was causing my WiFi dropouts.

Yeap removing this ‘Wifi Map’ app got my wifi issue sorted out. Not sure what that thing was running in the background but never lost connection again…

Removing Wifi Map app seems to resolve this annoying issue for me as well! No WiFi disconnect for the last 24 hours

I just got the iphone 12 mini and was having this problem, too. I turned off the wifi assist and haven’t had the problem since.

I've been in contact with senior support for a couple of weeks. Last week they installed 3 troubleshooting profiles to diagnose the issue. I sent over 1gb of logs to them. Just had a call that they couldn't replicate even with those logs so trying again (the issue occurred multiple times whilst profiles enabled). 

I'd recommend anyone with the issue to escalate when speaking to support. The more logs they have the easier it will be for them to ascertain the issue (and harder for them to ignore). 

A also tried switching off private IP. It works for me. I have had my iPhone 12 Pro Max since 15 November 2020 - 7 months. I have tried all the things people have suggested, even though I didn’t always understand them. In the few days since switching off private IP I have not lost the WiFi signal once. Up until now it was happening several times every day. This seems to be an excellent solution. I agree, though, that Apple should have sorted this, especially as we’re now up to iOS 14.6.
