iPhone 15 Pro Max Wi-Fi Issues

I strongly doubt that everyone experiencing issues described in the thread has VPN activated. I didn't when I had problems, at least.

Exactly why my issues have stopped, is hard to answer, but at least I'm happy it's stable now...

I'm having the same issue with my new iPhone 15 PRO MAX. It is so frustrating as I'm trying to set it up and it will not connect to my wifi and hold the connection. My iPhone 14PRO MAX has never had an issue and is sitting right nest to it and both on the same software.

Exact same thing happened to me - they called and I was dumfounded for a second that they 1) were reading this and 2) cared enough to call and collect data to fix it. The guy was very professional, polite, and understood the manifestation of the problem clearly. I will be looking forward to the release notes of the next update - hopefully this fix gets included. I will also post the outcome of the new quad band router experiment for more information once I get it up and running.

Same issue happens to me on my iPhone 15 Pro Max and Unifi UDR router. As stated back on the reddit thread I've been involved with, my only solution is to disable the 160MHz channel option on my UDR device.

If anyone at Apple wants, I'm more than happy to help provide additional diagnostic tests to get this issue fixed.

I'm having the same issue, iPhone15 Pro struggles to connect to my 5G Wifi. Other phones (i.e. iPhone 14 Pro) and devices (i.e. iPad, Macbook) work just fine so the issue revolves around the phone.

The phone connects to the 2.4g but struggles to connect to the 5g and when it does connect it might work fine for a bit but then the internet will essentially stop working (even though it still shows it's connected with 2-3 bars). Sometimes it will consistently drop the connection.

Summary: struggles to connect to 5g, will drop connection on and off, even when connected will struggle (Site can't be reached ERR_CONNECTION_TIMED_OUT)

Just wanted to add my voice to this issue and hope that Apple finds a solution soon.

Thanks for looking into this!

WOW there seems to be a common link with most of us having this problem which is we are using ASUS AX routers, I have ASUSWRT-Merlin running on mine and have the same problem where my pro max says its connected to wifi but I cant access the internet. I just updated from a pro max 12 which worked fine for 2 years on my RT-AX88U router.

My guess is that it will be something simple, either a firmware or driver issue that will get patched fairly quick, most years it seems there are wifi/internet issues with the latest models and they are usually patched in the .1 release that comes 2-3 weeks post launch, 17.1 I assume will be the same and also contain the iPHONE 15 optimisation settings. In saying that it is still **** annoying, i usually turn off wifi and mobile data then turn back on to fix but have had a few occasions where I have had to reboot the phone. I have way to many devices connected to turn smart connect off so i am stuck waiting for a patch from Apple or ASUS or both

Apple reached out to me aswell, but due to time zones and other factors, I haven't been able to contribute yet.

It's nice to see how active they are and how seriously they are taking this. My guess is that the share of affected units among the recently shipped 15 Pro and Pro Max is very high, and that they therefore do everything in their power to avoid a "WIFI Gate" from snowballing more than it already has.

Iphone 15 Pro max, I’m also have total data blackouts, on LTE/5ge/5g/5g+/wifi. I have to turn on airplane mode and turn it back off to reset. I have an unlimited data plan through AT&T. Is this a apple or service provider issue? Anyone else have issues when not connected to WiFi?

Wifi problems with 15 Pro Max where none existed with 12 Pro Max. Running mesh network 2.4 and 5 ghz on Deco mesh network. Works great for everything else. I mow my lawn on riding mower with phone in pocket and over-ear bluetooth headphones for ear protection while playing music from app on wifi. Been doing it for years with 12 Pro Max and iPhone 7 Plus before that, and iPhone 6 Plus before that... and can go really far away from house without drop outs. Even my old iPhone 5S (still have that one) works better.

Now with brand new 15 Pro Max, it's completely useless. Drops out right next to the house with perfect signal, then I have to stop and reconnect constantly. Everything looks fine but app disconnects and says no data. And in same areas inside the house where I could get 200 to 300 Mbps with other phones, I get like 130 Mbps max on this phone. What gives? I'm not going to compromise my entire network and change things just for this phone. Thinking it's defective or something at this point. I thought maybe it was my new phone case at first but it's the same with or without the case.

Same here, tried several wifi networks and switching to 80Hz band, even tried sharing the ethernet connection from my Mac to the iPhone. Would connect but drop instantly. Deleted the NordVPN app and config on my phone and it connected just fine. 6E working great now and getting 1gbps over wifi

I hope this helps someone I have been having the same issues as everyone else for days. Been on CenturyLink as my ISP and an old outdated router for some time and been wanting to switch to a new ISP for some time. Well finally confirmed with my apartment complex Xfinity is offered. I switched today new Gateway Router through Xfinity and with the new ISP no issues whatsoever getting 1GB download. I was worried it was the iPhone 15 Pro Max now pretty sure it’s not a phone hardware issues. Hope this helps others!

UPDATE: ok so I received the new router (AXE-16000 Asus 6E) I have segregated SSIDs as follows:

1) 2.4gHz

2) 5gHz (running 20,40,80,160mHz)

3) 5gHz(running 20,40,80,160mHz) with the same SSID as the second band

4) 6gHz Wifi 6E running all bands with a separate SSID.

The iPhone 15 pro max connects to the 4th radio running the 6gHz frequency. It performs almost flawlessly (enough for me to be satisfied with it) and it does not have the disconnecting problem. HOWEVER - if you connect the 15 pro max to the 5gHz networks (either radio) it has the same problem with the 160mHz band. BUT it runs nearly perfectly on the 160mHz band on the 6gHz network. This is an indication (but not solid proof) that this may be a software issue. The only troubleshooting I am not able to do is connecting another device to the 6gHz radio as I do not have another 6E capable device in the house at the moment. I am working on that and should have an answer for this by tomorrow evening.

Hopefully some may find this helpful - I have a call scheduled with Apple on Tuesday evening (I originally didn't anticipate the router arriving until Monday so I hedged my timeline lol)

I already did that and it did work - but my issue was that the speed wasn't as fast as it should be on the 160mHz band. I was trying to see if the issue was specific to 160mHz processing or if it was related to the wider band (5gHz vs 6gHz etc). I still think that since it does 160Hz on the 6gHz band that the disfunction on the 5gHz band on 160 is likely software related. What do you think, Fozzy?

Found a solution which has created other problems for me.. I have Xfinity, and was able to go into the Xfinity app, WiFi settings, and turn my security mode to ‘WPA3-Personal’ instead of ‘WPA3-Personal Transition.’

This has fixed my issue with the 6E WiFi holding steady on my phone from room to room but now my older devices, such as smart plugs, and google assistant are unable to connect unless revert my settings back to Personal Transition mode through Xfinity..

I’m certainly no expert on any of this and it’s driving me mad.

By chance does anyone have a VPN app on their iPhone 15 Pros? I had Private Internet Access (PIA) and after removing it my phone stays connected to the WiFi.

For what it's worth, I set 20/40/80 on my Asus router RT-AC5300 on the 5G band which helped a little, but removing the VPN was the solid fix.
