iPhone 15 Pro Max Wi-Fi Issues

I called and reported the issue and they tried to help me fix it to no avail. Since then someone else has contacted me who seems more experienced in these type of issues and is “collecting” data. Apple is aware of it but they have not found what the issue is as it appears not one of us is experiencing the same exact thing. Different routers behaving differently and some people are working around this issue removing their VPN, turning Airplane mode on and off, resetting network settings, changing router settings and the list goes on and on. Others, such as myself have tried all of that and my WiFi still doesn’t work. So, for as long as this is an iOS issue they will most likely eventually find a solution to it. If it’s a hardware issue… Well, that would be a completely different sorry. Only time will tell. I’m considering returning my phone until they fix the issue. It doesn’t work with my home’s WiFi.

Here's the issue:

Network standards must be adhered to by both the manufacturers of WiFi access points/routers and Apple.

Apple does fix issues when they are their fault, but they often are not.

I have a 15 Pro Max and I have had no issues connecting to or using any WiFi access point that worked with my 14 Pro Max.

However, I do not have a WiFi 6E router, so I can't comment intelligently on 6 GHz issues.

The first thing to do when experiencing difficulties is to make sure your WAP/router is running the most up-to-date firmware available for it; from there you can do further troubleshooting.

This is not meant to disparage anyone's issues, but rather to point out that the only way to find and resolve issues is to be grindingly thorough, starting with the basics.

have the same Asus router setup with Ai Mesh and having the same issues. no resolution just found yet. iPhone 14Pro Max on same network has no issues along with 20 other smart home devices. only my iPhone 15 Pro. seems to sometimes disconnect when switch ai mesh nodes or leaving the house for a few hours.

How annoying, iOS 17.1 didn't resolve the issue.

My wife is rather *ed off that her new iPhone 15 Pro can't stay connected to the same Wifi that her 12 Pro and my 13 Pro Max have no issues with.

I run a ASUS TUF-AX5400 router and have a single SSID on 2.4 and 5Ghz.

This runs across 20 to 160 Mhz.

Apparently disabling 160 Mhz bands (slows your connection speed down a lot) keeps it stable.

Apple better fix this ASAP.

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.

Orbi 960 setup, i.e. Wifi 6E, 1 router + 3 satellites, fully wired backbone, and going from iPhone 14 Pro Max to 15 Pro Max meant that as soon as my iPhone 15 Pro Max jumps from the main router to one of the satellites it loses connection. In my case, turning off 6E on the iPhone doesn't help. Turning off private MAC address doesn't help. Turning Wifi off/on on the iPhone doesn't help. No VPNs running, either. And my "iPad Pro 11" Gen 3" still continues to travel from room to room without losing any signal as my iPhone 14 Pro Max used to.

Initially I blamed Orbi, so went ahead and replaced it with a brand new Eero Max 7 setup, i.e. Wifi 7 (not that it matters for iPhone 15), 4 identical devices (in 1 gateway + 3 extender mode), and guess what? The exact same issue!! Perfect 6Ghz connection to the gateway, but no connection to the extenders. Argh! More correctly, the extenders see the phone connecting at 6Ghz, no problems. And the phone shows it is connected to my network. Just like under Orbi. Yet, the little circle thing keeps spinning forever next to my network name, effectively killing any connectivity, including cellular. This is not okay... Eero has two features: Turn on Legacy Mode in case 6Ghz devices don't work. Didn't help. It also allows to turn off 5Ghz for 10 minutes. Didn't help. Although I am not sure if that actually makes just the gateway go into legacy & 2.4Ghz-only mode or all extenders as well...

I am now walking around the house with my iPhone's wifi off, hoping that the meager AT&T cell signal around me will be enough. When I need the full bandwidth, I go to the room with the Eero gateway, turn on my iPhone's wifi, do my thing, turn it off, and walk away. Hardly the Apple experience of the yesteryear...

I am disappointed that iOS 17.1 did not fix this.

Well... Reading the entire thread, about 23 pages since its start, it is clear that people are also having this issue on their Orbi, Eero, Asus and various other mesh systems. So, that must point to an issue with all mesh systems and not iPhone 15 and/or iOS 17, right? :) It is the phone & its software.

Similar Situation here but strangest thing is it only seems to happen when connecting to other network devices like tv’s (I use the Roku app with remote on my phone). I can literally watch the wifi icon disappear when I go to the Roku app. Then if I got to wifi settings it shows it connected and the wifi icon is there. Go back to Roku and it flips to LTE.

after several back and forth tries it works but will eventually disconnect again. No rhyme or reason. My iPhone 12 max pro didn’t have this issue at all. Everything is the same except my phone!!!!!

Personally, I've had no issues with my 15 Pro Max and any Wi-Fi network I've tried, but obviously that doesn't help you.

Remember to make sure your Wi-Fi access point is running the most recent firmware available for it.

This is especially true if you have a Wi-Fi 6E-capable router and your issues are resolved by shutting Wi-Fi 6E off.

Always make sure you have the most recent firmware update available installed on your router.

There's nothing wrong with Apple's network quality in general; virtually every issue here is with the implementation of Wi-Fi 6E among various wireless routers.

There have been no issues with commercial/professional solutions and for home units make sure you have the most recent firmware available for your device installed.

There are so few Wi-Fi 6E devices in the field many manufacturers are still shooting from the hip so to speak.

If you find a specific bug, let Apple Support know.

Wow. This worked instantly. I also had Nord vpn but hadn’t logged in since activating new phone earlier today. VPN toggle was flipping back and forth. Logged I. To NordVPN and went back and it had stopped and I was on wi-Fi.

Your older phones do not implement the newer Wi-Fi standards.

I suspect your router does not properly implement them either, thus the problem.

Make sure your Wi-Fi router is running the latest firmware the manufacturer has made available for it.

So I just upgraded Bell service to 3GB mostly to get the hardware upgrade to the GigaHub from the HomeHub 3000.

Issue: Resolved

It is definitely something with the firmware in some of these modems not playing nice with the newer hardware. I had the latest HH firmware, but unlikely they were too worried about maintaining that.

That is really not advisable to include non-wifi 6e channels on the same SSID. The same goes for wifi 6 channels. Three SSID’ are the best approach to isolate lower performance devices.
