iPhone 15 Pro Max Wi-Fi Issues

15 pro with Bell Home Hub 3000. Newly replaced fibre cable and modem. 17.1, issue went form intermittent at first to persistant across updates. Attempted reset network. Power cycle and forget network and re add. Advanced data protection and private rely are off. Issue is across all apps. Issue is worst with media, if the wifi works it’s for Reddit and apps like stocks etc.

Interestingly I am continually getting Wifi Associations failures on my iPhone 15 pro max. My phone drops to 4G and when I try and join the wifi network it says the password is incorrect. Reboot the phone and everything comes back up fine.

Definitely something wrong in the code for the 15s somewhere.

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.

A friend of mine, systems engineer told me that I needed a new modem with compatible newer technology. He hooked up a new Google HD2 modem to my older Bell modem via LAN cable (behind Bell’s)

Then, follow standard procedure for the new modem (assign a name and password for the new one) Fixed within 10 minutes

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

Seems like this issue has returned with the recent update. I haven't had a problem since November '23, but after installing the recent iOS update my 15 Pro Max is back to the 2.4ghz network. No other devices on the network are having this issue except for my 15 Pro Max.

I have an eero network (not for much longer) and it doesn't off much control over the network. I used the wireless scanner tool and see my 5GHZ network is at 160mhz width. Is the channel width the cause of the problem? With eero I have no control over channel width and channel, but I suspect its fine as a 14 pro has no issue.

what I've tried:

• Restart phone, network, and modem

• Hard restart phone (5ghz connected for 30 seconds then bounced through the nodes and back to 2.4ghz)

• Reset network settings on iPhone

• Forgot network multiple times

160 MHz wide channels have higher noise floors and much narrower ranges - typically you need to be within eight to ten feet of your WAP at most and line of sight with no walls, plus susceptibility to interference is vastly increased.

The iPhone 14 Pro does not support 160 MHz wide channels.

New update out today. Let’s hope it all helps us out

That is really not advisable to include none wifi 6e channels on the same SSID. The same goes for wifi 6 channels. Three SSID’ are the best approach to isolate lower performance devices.

leave the house and then come back in to automatically reconnect to the wifi and see if that triggers the issue.

I had this same issue!! I saw on another thread that deleting your VPN (even if it isn’t downloaded) worked for someone so I tried it and it worked!!!! I was so annoyed with this phone before

No, VPN applications may interfere with the operation of the device if not written properly.

If deleting the VPN fixes the issue, contact the developer of the VPN app.

Thanks, you're comment helps me a lot. I got issues with my wifi after i use a vpn. After i restart my vpn and reset my iphone settings for the vpn everything went back to normal.

Same issue happening for me on the iPhone 15 Pro. It'll connect to my home wifi and then periodically disconnect every ~45 seconds only to reconnect five minutes later. No issues with the wifi on any other device in my house. And the funny thing is the iPhone continues to say it's connected until you go to settings where it occasionally updates to say "No Internet Connection." Perhaps it's an issue with IOS 17? I'm hoping it's not a hardware issue.

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.
