iPhone 15 Pro Max Wi-Fi Issues

You are the man!

this was it for me too- deleted google one vpn and connected right away. After hours of frustration.

Yes. This is the solution that I provided to everyone here a couple days after the 15 Pro was released. Replacing the router fixes the issue.

Try turning off Password and Keychain sharing in iCloud. That fixed it for me.

I just received my 15 pro max and have the same issue on WiFi 5Ghz. I have just disabled 160Mhz on my router and will see if this issue goes away.

Deleting the VPN solved the problem for my iPhone 15 Pro Max.

Hello Guys

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

There's nothing to fix; check to make sure there isn't a firmware update available for your Wi-Fi router.

It is.

It's likely an issue with 160 MHz wide channels on the ASUS; the 15 Pro Max is likely the first device you've owned that supports them.

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 Been on CenturyLink as my ISP and an old outdated router for some time and been wanting to switch to a new ISP for some time.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!

I've send Apple Support a message through Twitter/X which led me to the Apple Support website to go where you select what device then what the issue is. Which then led me to opening up a conversation with Apple Support in Messages (text convo). I've send a message then right away got a message saying "Let me connect you with someone who can help. etc etc Apple may record, use, and keep a transcript of this conversation..." Just got a message from a support person, Shivakumar, gave the niceties (Thank you for reaching out and giving details, etc). In conversation with support now, will update later, but a diagnostic will be run. My parents suggested I go to an Apple store to see what is going on. Which I still may do, depending on what I get from Shivakumar.

Yeah. It didn't help. The diagnostic showed my "...device is more than fine. Everything should be working." Then he suggested to reset the network settings. Did that, it did nothing other than waste my time and energy. And then he said to do a forced restart of the device (quick press and release of volume up, then of volume down, the press and hold of the power button). I did that, it took a few tries tho. It looks a mintue to get back on the wifi, but it seems to be holding. Time will tell if it will stay that way.

Same issues, horrible wifi speed test, unreliable wifi connection..

what worked for me, so far:

went to cellular settings, changed from 5g auto to 5g on and data mode to allow more data on 5g..

will keep an eye on it, but im hopeful.

They only down side of 160mhz bandwidth is that it is also in the setup in DFS channel spectrum, to reduce interference with other frequencies.

I agree that 80mhz is at 1.2Gbps in theory but in reality it’s like 800-900Mbps. My goal was to get to 1Gbps that my service provider delivered.

Only the iphone 15 Pro models allow you to use 6Ghz channels. I doubt that the people having issues here even have a Router that supports 6Ghz channels.

If the 15Pro tries to find 6Ghz channel router and doesn’t and gives up doing anything is an obvious bug. Our there any settings to disable 6Ghz channel or wifi6e features?

If so, the iphone 15Pro will be no worse than all other iphones running wifi6.

Turning off 160Mhz bandwidth mode should be tried as well.

Each SSID that is detected by your phone can be set for automatically connecting or not. So your other router SSID’s that you don’t want to use will not automatically connect.

My network started with 2.4Ghz so I kept that SSID for older devices. My 80Mhz 5Ghz has a SSID and yet another for my 160Mhz 5Ghz so I picked the SSID for my 160Mhz to automatically connect when in range. The others are only available if I say ok to use them when my phone asks me if I want to.

Does your router even support wifi 6e? If so, it may have AFC enabled or always on for use of the 6Ghz channels. If it does have AFC enabled/on the router will follow rules of use of the channels similar to 5Ghz DFS channels. Basically you can get kicked off the channel your router is using and your router may or may not switch you to a non-AFC channel.

If you don’t want to deal with this AFC/DFS channel rules you will have to setup a SSID with channels and bandwidth that don’t overlap with DFS or AFC channels.

DFS rules basically started with wifi6 prior to wifi 6e.

There are over 47,000 licensed AFC users that can force your wifi 6e router to kick you off the channel you are using.
