iOS 17.2 WiFi connectivity issues

I updated to iOS 17.2 and have been experiencing WiFi connectivity problems and related speed problems. I can usually “fix” this by powering my phone off (iPhone 13 pro max). Sometimes I have to power off more than once. WiFi calling also seems to be having issues (randomly not working). Anyone else having either of these issues?

Not sure if this will help anyone else, but I've found that the iPhone/iPad in particular have a very sensitive-to-interference WiFI network adaptor. I've been struggling with this for a while, but have solved the problem for me, anyway. I have 2.4 Ghz and 5 GHz being broadcast over the same SSID. It didn't matter which bands the iPhone grabbed, I was getting awful performance (single digit Mbps down and up). I know all 2.4 Ghz bands are saturated around me, but I was puzzled on the 5 Ghz. In any case, I changed the 5 GHz channel from the default of 32 (5180 MHz) to 149 (5745 MHz) and voila, the iPhone's WiFi is blazing fast.


This may also explain why others experience it and others don't. Different devices respond to RF / WiFI interfence (this increasingly becoming an issue) differently, it all depends on the network interface adaptor. Some are more resilient than others.

Iphone 14 plus, IOS 17.2.1


Tried turning off the "private wifi network" but my phone still disconnects when I move away from the main router when I try to connect to one of the nodes, I am given the error message that password is incorrect. The only way to reconnect is to return to the main router where I connect easily (and without reentering the password).

I have an iPhone 12 Pro Max


Since all of the iOS 17 updates, including current iOS 17.2.1, I have horrible cell(Verizon)reception and my device download speed is 2 Mbps even though my WiFi speed is running at 1312 mbps.


I’ve closed apps, turned phone off and back on, deleted internet and cookie history etc. And I’ve only used about half of my 512GB of memory. Phone has never been like this.


Mean my iPad 7 is working fine on the latest update.

Still having major issues with connectivity to WiFi with all my Apple devices! (iPhones, Apple Watch, iPads, Mac). When is Apple going to get this fixed! Extremely cumbersome especially for iPads and computers! They have know of this issues for over 3 months and still no fix! Anybody have any tips. Have reset networks on all devices, shut off and on so many times! No other devices but Apple have this issue.

It's driving me crazy. I know it's the update that has broke my phone doing all the same things everyone else is describing. I have to travel an hour and half tomorrow to go to an appointment in Cambridge for the Apple store to look at it. I'm going to be so mad if they say it's faulty and make me pay for the fix. It's only 18 months old. I have spent my entire day today from 8:30 am right till now trying to sort it out. Hours on the phone with Apple tech then factory resetting. It's a joke Apple. Just own up and take responsibility and fix it
