iPhone 15 Pro Max Wi-Fi Issues

Are your devices setup to send the same SSID?

Note that the only Apple devices to support Wi-Fi 6E networks are:

• MacBook Pro (14-inch, 2023) or MacBook Pro (16-inch, 2023)
• Mac mini (2023)
• Mac Studio (2023)
• Mac Pro (2023)
• iPhone 15 Pro or iPhone 15 Pro Max
• iPad Pro 11-inch (4th generation) or iPad Pro 12.9 inch (6th generation)

So unless you have one of those, they won't even using 6E and so only your iPhone would find any errors involving the way your Wi-Fi access points are implementing 6E (or 7.)

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.

I’m also having issues with WiFi! All iPhones in the house never go below 3 signal bars, especially the way the WiFi is setup in the house. It even disconnects. Absolutely annoying and I hope it’s not a design issue

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.

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:

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