iPhone 15 Pro Max Wi-Fi Issues

Having the same issue. Tried resetting network settings, restoring with and without iCloud backup, went to “Date & Time” and turned “Automatic Time” on and off, forgot wi-if network, powered phone on and off… everything. Planning to return the phone tomorrow if I can. Please fix Apple!

Same issue exists on 6G SSID

IOS: 17.3 Model: 15 Pro max Region: India -Network and wireless turned off -Tried forgetting the SSID -Reset Network settings on the phone

Router: TP Link Archer AXE95 5G WiFi Band: WPA3/ WPA2, Channel Width: 20/40/80/160, Channel: Auto, Mode: 802.11a/n/ac/ax mixed

6G WiFi Band: WPA3, Channel Width: 20/40/80/160, Channel: Auto, Mode: 802.11 ax only

Kindly let me know if any other suggestions.

Note: I had already factory reset my device twice on the same day before I observed this issue

I had this issue. Tried the fixes above, but no success. However, I deleted a VPN that I had which was connected to an app called Covenant Eyes. So far it seems stable and working. Didn’t have this issue on my iPhone 11 (just upgraded from).

How has this not been addressed and fixed by now.

We have several iPhone 15 Max and new MacBook Pros that we cannot use the 6Ghz channel due to the devices disconnecting at random. I’m getting super frustrated as I keep texting after each update if it’s been resolved.

I can be just sitting in the couch not moving and my Laptop disconnects from the AP and I have to reconnect. A connection will last 5 min to 30 min. Phones randomly disconnect and start using carrier data.

I have to turn of the 6Ghz completely it’s frustrating as heck.

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.

No one from Apple is here to acknowledge anything; we're all just fellow Apple users.

I would advise you to check the Ubiquiti forums - they release new firmware betas more or less weekly and official firmware revisions quite often to try to address issues like this on a wide variety of hardware.

As I write, this is the latest firmware for your U6-Mesh router, released February 2, 2024; make sure you're up to date:

UniFi-Access-Point-6-6-65

Note also that the use of 160 MHz channels makes you very prone to interference, only works very close to your WAP (generally within about 15 feet), and requires the use of DFS, which means your WAP has to stop transmitting and change channels anytime it detects aviation RADAR signals.

I'm also having issues connecting to the 5ghz wifi. Changing the bandwidth to 20mhz, 40mhz, nor 80mhz did not work for me. It might connect to the ssid but no internet.

My other devices are connecting and working fine. Just my iPhone 15 Pro Max is having issues. The chat support through the Support app was no help and does not have a fix and suggested calling instead.

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.

I found that manually changing the DNS to Google's public one, 8.8.4.4, leaving it on that DNS for 30 minutes and then getting rid of that configuration seems to have fixed my issue at least for the past 12-14 hours. We'll see I suppose but it might be worth a try for you since I had the exact same issue you describe with my 15 Pro.

I have an AX88U and have never had this issue with any other device other than this iPhone 15 pro max. I wonder if this is fixable with a software update at all or if it's a problem with the wifi/baseband chip. Has anyone actually resolved the issue? I have checked around other places on the internet to no avail (and I see you have been other places as well so thank you for the effort to highlight this problem).

Interesting. I have a 3rd generation iPad pro 11 inch and it cannot get wifi6E. My only compatible device with wifi6e is the iPhone 15 Pro Max. Once I toggled off that option on the phone, my speed was at least bearable. It is still slower, and I believe it could be doubled, so I'm troubleshooting further tomorrow. I'd recommend at least toggling wifi6e, as in my experience, this issue only showed up after I installed 17.03.

Example:

ios 17 before 17.03 speeds were 800MBPS (crazy fast) on a 1.2GBPS network with wifi6E enabled. Other support artcile I found helpful

ios 17.03 speed with wifi6e toggled off: 300mbps. Not bad at all, but I want to utilize the full functionality of the device.

I would recommend you work with Apple Support directly.

I have never seen Wi-Fi fail on my 15 Pro Max, so whatever the issue is, it's not universal so the best bet at finding a fix is to work with Apple.

Contact - Official Apple Support

Visit an Apple Store; if you can't connect to their network, then have them examine your device:

Genius Bar Reservation and Apple Support Options - Apple

Alternatively, contact Apple Support directly:

Contact - Official Apple Support

Also make sure any VPN apps you may have are uninstalled.

You are not speaking to Apple Support here, only other Apple users.

Other Bell Home Hub users are also experiencing issues, which points to an issue with the Bell Home Hub.

That sounds like an issue with your network at work; many corporate networks block the ports used for Wi-Fi calling and other services resulting in the behavior you report.

You cannot state that because an iPhone 13 works it's an Apple issue because the iPhone 13 did not support Wi-Fi 6E; if your router does, it may be an issue with their implementation of it.
