iPhone 15 Pro Max Wi-Fi Issues

I updated to 17.1, and the Wi-Fi is fixed. Although toggling on "Private Wi-Fi Network" causes it to become unstable. Try toggling it off and see if that does anything. I'm also on a 5GHz network.

Just wanted to chime in with my experience on this topic. I was having the problem that everyone else in this thread was having with spotty connection and dropping the signal when connected to 6E WiFi. I was having to disable the 6E mode on the phone to run it on 5ghz instead. I ended up opening a support ticket with Apple Support and was told that everything looked fine from their end after running diagnostic tests. The last thing I was to connect with internet service provider and see if there’s a bug or something on their end.

I contacted Xfinity, my internet provider, and everything looked okay on their end too, but after prying a bit they detected an issue that could be causing the problem. They did a reset of the router and update from their side which has seemingly resolved the problem for me, for now.

For me it was as I was trying to transfer to the new phone. Then I saw the VPN toggle in setting flicking back and forth. My original phone had Nord VPN loaded and I used it when travelling.

I went to cellular, down loaded Nord VPN (which had not transferred as I has no wifi connection). I closed Nord VPN down, then I could trunk the VPN toggle off in settings. Now a solid wifi connection.

I assume there was a VPN setting that came across with the network setting transfer which was shutting down the wifi while it tried to load.

First, Apple is not here, we’re fellow Apple users.

Second, make sure your router is running the most up-to-date firmware available for it.

Your iPhones are some of the newest Apple devices to support the Wi-Fi 6e standard and the 6 GHz band, and many routers don’t have their support quite debugged as of yet.

A lot of irrelevant fixes and replies so let me chime in and hopefully someone from Apple can reach out.

I have a wifi 6 mesh network from ubiquity. The iPhone 15P will NOT stay online using 160mhz channel width.

It was dropping anywhere form 1-5 minutes constantly without fail despite showing as connected to the network. This botched my setup process really bad since I had no idea why nothing would pull from the cloud unless I kept manipulating wifi.

Anyway, I disabled 160 mhz channels and its back to completely normal. This is either a WPA3 or network handshake issue, or some ungodly chipset incompatibility between whatever ubiquity is using and apple. Either way huge numbers of ppl are affected and im surprised I did not hear anything about this before buying 4 months into release.

Please someone acknowledge and let us know what if anything can or will be done on the iPhone side.

This is going to impact a ton of my deployments and honestly not sure if ubiquity is to blame here either since neither company wants to even take the effort to make any official announcement.

I'm having the same issues with my new iPhone 15 Pro. However, my router (TP-Link Archer AX5400) was already configured to 20/40/80, without the 160hz option toggled on.

My phone varies between accepting the WIFI and rejecting it. Once it's connected it sometimes works perfectly and sometimes not at all. The phone purposely disconnects, and thankfully 4G/5G is good enough for now...

One thing worth looking deeper into is the "Smart connect" feature, or whatever it might be called by your router manufacturer. The feature means the 2,4GHz and the 5GHz bands are merged into one (for the user) instead of broadcasting both and the router passes the device over between the two when needed. I have this feature activated and someone said "once I toggled it off, the 5GHz band could be used without problem, at 20/40/80"

I have not yet tried toggling it off, since it affects all my devices, but still want to contribute to the thread, that it might be worth trying, in case you're in my situation.

Update - I've troubleshooted through some suggestions of changing the wifi channel and bandwidth and nothing really worked. As a last ditch effort, I dug out an old TP-Link RE230 wifi range extender to test it out. I set it up both as a range extender (picks up existing wifi and extends it) and access point mode (connects to existing wired network and change to wireless) and my iPhone was able to connect to the 5ghz wifi with internet on either! The speed is not the best, but good enough. I'm getting 30Mpbs down/25 up on 2.4ghz wifi. And 93down/93up on 5ghz wifi. I'm not sure if the iPhone 15 have a new wifi chip/modem that's having trouble with some manufacturer's routers. I wouldn't call this a complete success because it should just work out the box, but it's better than nothing.

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

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

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.

We had the same issue and noticed that the VPN switch in the settings was constantly flickering, turning on and off multiple times per second… reading „connecting“. We use the 1.1.1.1 app for VPN. Right after moving from the old phone to the new, it seems that the VPN settings were synced, but the 1.1.1.1 app was not yet installed. At some point the 1.1.1.1 app was downloaded and VPN switch in the settings stayed constantly on. Since then the iPhone has had no connection issues.

So perhaps before moving from an old iPhone to the new one it‘s a good idea to turn VPN off?

Hi all,

If this helps anyone;

I bought the new Apple iPhone 15 Pro and couldn't connect to our Centurylink 5Ghz wifi. It connect to 2Ghz but not 5Ghz.

I spent 2 hours a day for 3 days rebooting the modem, rebooting the phone, changing every setting on the router, resetting the router, resetting the phone and finally gave up.

I returned the phone to Verizon.

After getting a second iPhone 15 Pro in the mail today we turned it on, and YET AGAIN, no wifi even though over 30 devies in our house are conneted to the wifi network.

I found out via this thread that the cause IS NOT the iPhone, it's Centurylink's outdated routers that they use in apartment buildings:

https://www.reddit.com/r/iphone/comments/16p3mm2/iphone_15_pro_pro_max_wifi_issues_with_unifi_udr/

Forcing Centurylink to replace their modem/router solved the issue for us.

I was having the same issue and reading through all of these replies. Got to this one and checked my VPN. As soon as I looked at the VPN, I saw the slide button toggling on and off by itself. I removed the VPN and my phone immediately connected to the WiFi with no problems. I have Norton. I’m gonna message them with a heads-up in case there’s a fix on their end.

Same issue here. I have an Iphone 12 Pro max, no issues. I've also recently had a Z fold4, no issues. but since I've gotten the Iphone 15 (pro max). lots of connection issues. I have no connection/internet issues with all other computers/devices on the network (including Ipad).

I also have an Asus Router. (AX88U). and I also had 160MHZ turned on. I have just turned it off to see if that helps.

One last bit. Asus just released a new Firmware. but the update had no effect on the issues.

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:

https://rog.asus.com/us/networking/rog-rapture-gt-ax11000-model/helpdesk_bios/

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.
