iPhone 15 Pro Max Wi-Fi Issues

I’m on my second iPhone 15 Pro Max. The first one wouldn’t set up properly and had the connectivity issues as described in this thread. Verizon replaced it for me. I have my new 15 Pro Max, and it started well. But I’m again having the same connectivity issues — unable to connect to wifi, connected to 5G but apps don’t pull data through.

It’s maddening.

Once I disconnected the VPN in settings, my Wi-Fi started working. It kept trying to connect to the Wi-Fi and the VPN automatically and it just would not work. Now I wonder how to turn my VPN on and use the Wi-Fi at the same time but I guess I don’t really need to worry about that if I’m at home right? Anyways, hope this helps.

I think I’m close to figuring it out, it dropped again, and I dug into the logs from my router and I can see it going through a channel change, but the iPhone 15 Pro Max does not properly acknowledge that change and transition to the new channel. It just loses the connection entirely. I’ve had it happen on times where there are no channel change, so I’m starting to think that there is something wrong with the phones that they are not able to properly handle steering requests in general. So having channels set to auto and/or having a multi-band setup will likely cause this issue. I’d be curious to see if anybody is having an issue where those conditions are not met, meaning you have a static channel and only one 5GHz band.

This is truly the worst phone I have ever owned. Bought the top of the line pro max. Randomly dropping away from cell connection, messages of. ‘No internet connection’ and certain apps won’t work. Had to install NordVPN three times before it worked for example. Always been an ‘Apple guy’ but seriously considering going android. Battery life also sucks.

Same issue with iphone 15 Pro! (with Asus routers AX 86U and AX82U setup as a mesh)

Additionally, I have also had erratic issues with my 5G cellular network requiring ocassional flightmode-on-off to fix internet access. No VPN

For those that have been in contact with Apple, have they provided any details on how this will be or if it can be resolved? I rely heavily on my wifi in order to use my iPhone 15 Pro Max from home. The cellular service in my area is inconsistent. Not being able to keep a regular connection to the internet is maddening. I connect to my service providers wifi modem (Bell Homehub 3000 in Canada).

$2000 on a iPhone I can't use might have me second guessing continuing my regular use of apple products & I own them all, laptop, iPad, iPhone, watch, etc.

Any tips or assistance would be appreciated.

I'm using 6E and experiencing the iPhone 15 Pro Max not only dropping my home WiFi, but also forgets the network's password, as if something in the config has changed.

It knows and recognizes the network, but I have to re-enter the password to re-join.

I'm currently cycling through all of the 6 GHz channels to see if it's noise-related, but based on what I'm seeing here, I'm doubting it.

Hoping Apple finds a fix for this soon.

I have the same issues with my 15 Pro max. I have two Asus GT-AX11000s in a mesh configuration. My surfing was slow and laggy, until I disabled the 160Mhz bandwidth. This is a bandaid and does not fix the underlying issue. I never had this issues on my 11 Pro max. Please fix.

In most circumstances, 160 MHz bandwidth is going to be prone to interference and is going to have issues unless you live in an area where there is no other 5 GHz band traffic as it eats up the equivalent of eight normal 5 GHz channels.

Here's a good backgrounder from a third-party site.

Also make sure you have the most recent firmware available for it installed:

Your 11 Pro Max never had this issue as the 15 Pro is the first iPhone to support 160 MHz wide channels, so it would be the first to notice if there is interference or if there are other issues with 160 MHz channels in the router's firmware.

I’ve had similar issue. Was just on the phone with support and we got to the point of checking if vpn isn’t on and I noticed that the slider acts. It was like for a split second switching on and off again. I uninstalled tunnel bear vpn (that wasn’t on) and bam! Issue is gone.

hope that will point some people to the solution of a problem!

It is unacceptable to have this issue with the 15 Pro but like all of you my new phone (which I picked up yesterday) would not connect to WiFi regardless of what I tried until I deleted the VPN. This is a software issue and hopefully Apple will correct it before many of us switch to the Android.

I have the same issue. I am trying to get help from Apple but all they do is like reach out to your internet provider, delete VPN etc.

I have a iPhone 13 on the same IOS version and that one has no issues. None, of my other devices in my home has and issue. Only my iPhone 15 Pro has the issue.

I've seen a couple of people post my issue: I have no problems connecting to wifi with TP-Link Deco with three nodes at 160mhz and I get very good speeds. I also have no problems connecting at 80mhz when I forced the network to use that. However, whenever I move between nodes, ie move around the house, I get booted from the network, and whenever I leave the house, and come back, the same occurs. It really just has troubles with reconnecting to the network, in whatever form that may be, and forces me to sign back into the network, password and all, despite it recognizing it should be signed in already. If Apple engineers want to grab some logs from my phone I'd be up for it, I'm a software dev so I should be tech literate enough to help out in that regard.

Turning off VPN is not the solution. We never have used a VPN and still have the same issues as many others. My 5ghz bandwidth only goes up to 80hz so that is not the solution either to turn of 160hz.

We have updated our iPhone 15 devices to iOS 17.1 and we still have the same issues. So use of a VPN or 160hz bandwidth is not the sole reason for these issues because we use neither. All other Apple devices in our house are on the latest software and don't have internet or data issues. It is specific to iPhone 15 devices.

Same problem, brand new 15 Pro Max with an Orbi router system. Had no problems w my old iPhone 12 Pro Max, now I have to restart wifi constantly to restore internet. Worst thing is, I don't know it's disconnected until i try to do something internet-related on my phone, so I'm missing mail and like items. I rely on my phone for work, so unless Apple responds within this week, the phone is going back and I'm buying a much less expensive iPhone 14.
