Iphone 12 Pro Max Keeps Losing Wifi Signal

Hi, had my iPhone for just over a week and annoyingly everyday it keeps losing Wi-Fi signal at random points during the day. Only solution I have found so far is to switch Wi-Fi off in settings and switch it back on. Have reset router several times too. The problem is getting really annoying as I switched from Android after 15 years and have never had this issue with my previous Samsung 10 or Huawei P30 Pro and other android based phones. Anybody found a solution or is it a case of sending the phone back and going back to an android based phone?

I switched off wifi assist it’s in the setting/ cellular scroll all the way to the bottom


it appears to have stopped it from happening

apple put this feature in to switch to a cellar connection if a wifi signal is weak.


I was right in front of the router and it was switching so I just turned it off

Thank you for the suggestion, although not a solution for me as I don’t have a VPN on my device (iPhone 12). I am beginning to suspect a hardware issue. My son’s 6s has a VPN and he doesn’t have any connectivity problems. We have several Apple devices and no others are having the data connection problems the 12 has. The iPhone 12 also constantly disconnects from the HomePod so now none of the home automation works properly either.

VPN is Seperate issue and NOT the root cause of this problem. It should be on another thread as it's a different issue altogether. Two devices no VPN on either both experience this symptom and still happens in 14.5. We will be returning both devices for a full refund in the near future as Apple obviously has no intention to fix this problem so the devices are not fit for purpose

Guys, this is a little ridiculous. I keep having to switch WiFi on and off on this device to maintain connectivity. I’ll be in the middle of doing something in an app, and then the connection bombs out. There is nothing wrong with my router, as I just switched over from an XR, and it was fine. I needed the bigger screen size so I upgraded to the iPhone 12 Pro Max. You guys should address this.

I switched to an iPhone 12 and am experiencing the same problem. Have to switch WiFi on/off at least once a day. iOS 14.5 update did nothing. Is this defective junk or what? Apple needs to respond to this.


I use Google WiFi routers and have not modified any settings. And even if I did, WiFi stalling like this would be ridiculous. Obvious issue with the phone. Maybe bad WiFi chips in which case there needs to be a recall with free fix or replacement.

Yep still happening. I set my phone up as new, not restored from old backups. I am on AT&T, and usually only 1-2 bars of signal of LTE (sometimes zero, it's poor coverage) if that might make a difference (I know this is a WiFi bug but could be related).


It even happened when I woke up in the middle of the night when I needed to check something. Phone hadn't been in use for hours, just plugged in. Thought that was strange.
