iPhone 15 Pro Max Wi-Fi Issues

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.

If you believe it's your device, make an appointment to have your phone examined:

I use my iPhone 15 Pro Max on 5 GHz Wi-Fi the majority of each day with no issues.

The XB8 supports the new Wi-Fi 6E standard, so if it gets Wi-Fi 6E wrong, only some newer devices in Apple's product line would notice:

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.

It really doesn't.

The iPhone 15 Pro and Pro Max are some of the first devices to support the new Wi-Fi 6e standard and the 6 GHz frequency.

If your access point gets its implementation wrong, you will see every older device operate without issue but you will see problems with your new device.

If you still have the device you are moving from, this seems to have helped me:

• Reset phone from a computer connection (will force a fresh download of the iOS)
• Delete VPN config+apps and reset network stats on the old iPhone.
• Connect to the network from the old iPhone, with no VPN or other config
• Try to connect from the new iPhone

Seems like the issue is centered around networks where I have previously connected. This is currently working at my gym and workspace. Not sure about home network, yet.

Update: 5G wifi works for all other networks but my home wifi 5G still does not work even after updating to 17.1.

• connects to 2.4ghz network on the same router
• the phone detects wrong ip and subnet mask.

All troubleshooting steps listed in best order, stop between each and see if the problem is solved:

1. Settings > General > Software Update, apply any available update
2. Remove any and all VPNs and VPN apps
3. Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings, then reconnect
4. Settings > Cellular > Cellular Data Options > Data Mode, set to Standard
5. Settings > WiFi > Select i next to Wifi network, disable Private Addressing
6. Settings > WiFi > Select i next to Wifi network, disable Wi-Fi 6E mode
7. Settings > (Your Name) > iCloud > Passwords & Keychain, disable Sync this iPhone

But yeah, IMO this is more of an Apple problem. Wi-Fi APs aren't perfect, but compatibility is not just about adhering to a standard but testing the dickens out of multiple products to see if your device actually plays well in the real world.

Oh and my work wi-fi still drops out on iOS 17.2.1, after doing all of the above. Aruba WAPs on a controller, recently upgraded to new WAPs.

I’m having the same issue. Same router. But AirPlay in my car has intermittent connectivity issues as well

I saw his post and did network settings and it worked for me on my 14 pro.

Sooooo, I have to purchase a $179 router for my $1500 iPhone to work on WiFi?! Nope! Apple needs to figure this out.

Brand new iPhone 15 pro max and having horrible problems using WiFi. Super super slow. Had no problems whatsoever with old iPhone 12 Pro Max.

Hello Guys

All the people here already delete the VPN , maybe someone can update the post title remarking VPN deleted LOL

Having similar Wifi issues with AmpliFi Alien router and iPhone 15pro Max. Wifi 6 speeds are way less (300mbps) than Wifi 5 speeds (800+mbps) no matter the configuration or channel it seems. After a few hours the Wifi speed drops to almost nothing and I typically have to reboot the iPhone to get decent connection speed back. Phone is on latest OS.

This is the only device on my network with any issues.
