iPhone 15 Pro Max Wi-Fi Issues

Yes, 15 Pro and Max both support wifi 6e so the 6Ghz channels are available.

Maybe AFC licensed user in your area is kicking your router off 6Ghz channels, which must also support wifi 6e 6Ghz channels.

You should be near your router to make sure the signal strength is not an issue.

Google search for free wifi spectrum scanner apps for your PC or laptop.

These will map out all the router’s and SSID’s near you.

Make sure the scanner works with wifi 6e to be able to scan the 6Ghz.

I believe the computer/laptop must support wifi 6e as well. My PC has an adapter so I plan to upgrade it to a wifi6e version.

So frustrated with this wifi issue on my 15 Pro Max. Did what you suggested (created a guest network and joined) and my internet works. When I connect back to my main network on the same router, there's no internet.

Im having the same issue, I can connect at home, but as soon as I'm at school, where the internet works on my computer, it doesn't work, or even connect on my phone. Very frustrating for when i'm trying to 2FA or do things on my phone and computer simultaneously.

Ok, so after I created the Guest SSID on my router/modem (Bell Homehub 3000), I let my new Iphone sit over night on the Guest SSID. I tried switching to my home SSID this morning and there was internet connectivity. Been using it all morning. No issues so far.

The very first time i turned on my new Iphone 15 Pro Max, I could not log into my home SSID. At all. I had not transferred from my old Iphone (11 Pro Max). I wanted to update the firmware on the new Iphone before beginning transfer. The firmware before upgrade was 17.0.2. After the struggle of getting on my home wifi, many battles with getting and staying on wifi to download the new firmware (17.0.3), i finally got it downloaded and installed. New firmware installed but the wifi issue persisted. I checked the IP address in the new Iphone and it kept bouncing onto new addresses and not within the range specified in my router/modem. I checked my wifi device list in my router/modem and it kept generating new devices. It was odd to me because it seemed like the new Iphone was being recognized as a new device every couple seconds. I checked the settings of my old Iphone vs new Iphone for my home SSID. The only difference is the "Private Address." I switched it off on the new Iphone for both home and guest SSID. I then let my new Iphone sit overnight with the guest SSID and logged into my home SSID first thing this morning. It has been stable on my home SSID ever since. I just completed the transfer from old Iphone to new Iphone and it still works. Stable thus far with no issues.

Could it be my modem/router having a firewall preventing the new Iphone from hammering wifi logins (generating new addresses because of the "Private Address" functionality? My modem/router is old tech. 10-15 years. i have had modem/routers go bad over the years and replaced accordingly with the exact same model. This modem/router i have currently was replaced a few years back. Supposedly the "Private Address" functionality is IF the wifi supported it. I'm assuming this is a new thing which was not incorporated into my modem/router which could result in dropped wifi signal.

My advice, try switching off "Private Address" functionality on the wifi you're logging into and reboot modem/router. Hope it works!

I have a SE 2020 which has the private address feature for my wifi mac. I am running older ios 16.01.

So this feature is not new to the 15Pro.

My whole wifi network has this feature and the downside of using is that every time you reset/reboot your device the wifi mac address is changed. This causes websites to not recognize my devices and requires the third layer security to kick in. Basically the website has to send me a new code via my phone in most cases.

If your iphone is reassigning wifi mac address at a high frequency it will spend a lot of time connecting your device.

What wifi types like ax,ac and so on does your router support.

It should be at least a wifi6 ax type device to be able to support high wifi bandwidth.

So update on my end. Just got into the office and connected my phone to the network (it’s a 6E powerhouse). Went to go get a quick coffee outside my office and when came back my phone didn’t connect back to the network. I had to manually reselect the network again.

Maybe someone help this:

I was search for solution to get work 6E on my iPhone 15 pro, because at first when I just receive phone it was available to see and connect to 6E but after I restore it from my precious iPhone 14 pro copy wifi 6E cant be find. So I am make some tests reset my phone again and start from that point that it see 6E connection without any problems when it factory reset state.

So I setup it like new device and when I was enable Location Services it immediately disconnect me from 6E wifi connection and not see it more again.

So I go to Settings - Privacy & Security - Location Services - System Services and turned off Networking & Wireless and its connected to 6E WiFi again and working flawlessly on 160 mhz with 900+ mbps again.

For me it seems that Apple restricted 6E in Ukraine (where originally 6E not restricted) or its some kind of bug.

I think it may be just with the iPhone 15 Pro Max as my wife who has the 15 Pro does not have the same problem. At this point it’s only my 15 Pro Max that has the issue of automatically connecting to WiFi 6E mode when I’ve set it to ‘Off’. Note when it does switch itself to ‘Automatic’ I am unable to connect to my WiFi and then have to go into settings to turn 6E off.

At this point I’m just convinced nothing actually works. We need to wait for an Apple update here. At home, at the bar, at a restaurant, at the office…. Problems across the board and I just disable WiFi. I’ve tried everything and it’s just a false sense of ‘this works’. Every time the problem has come back. At lunch on Wi-Fi 5 network, same problem at this restaurant. One minute I’m good and the next I’m down again. Fortunately my cell act is unlimited.

I can’t connect to WiFi most of the time just doesn’t connect… other times it connects but there’s no connection. This is all on my iPhone 15 pro max and my 14 pro max works perfect on the same WiFi networks at the same time

Same I made a guest network and it works fine for me on my 15 pro max and when I try to connect to my main network it wasn’t working but I would say maybe 5-6 hours later when I retried to connect it worked.. but when I went to friends houses it wouldn’t connect so then I brought my phone to Apple and I showed them( because I took videos) and at Apple they connected it to there WiFi and it works fine so they told me there is no issue… so annoying

Try this as it worked for me.

Turn 160 Band off if enables including DFS

Either split or disable the 2.4Ghz wifi band - Seems this problem doesn’t like combined 2.4/5Ghz.

Make sure no 2.4Ghz devices are within 2 Metres of the router - If there is anything move them or the router to a clear spot.

If running ASUSWRT-Merlin 388.4.0 firmware roll it back to the previous version as this has a huge wifi and router reboot issue. Connecting the iPhone 15 Pro Max to ASUSWRT-Merlin 388.4.0 will kill your network the router will go into a reboot loop every 2 minutes.

I have no idea why the 160 Band with DFS and a combined 2.4/5Ghz network seem to cause wifi dropouts on IP15PM but since making the changes I have not lost connection once.

My guess is the wifi chip being used has some flaw, old firmware that needs updating or bad drivers. Whatever this is seems to be the worst launch issue since antennagate. Hopefully it can be fixed with a patch otherwise a few thousand iPhones will be getting replaced 😞

Nice to hear you found a work around.

Until the 15Pro/max, apple has never had to design or test use of 160Mhz with DFS. To make it more complex, wifi6e supported in the 15Pro/max must design and test AFC when the 6Ghz channels are being used. AFC is similar to DFS in that any licensed user can automatically tell your router to kick you off the channels overlapping with wifi 6 and 6e.

Setting up different SSID’s as you did is a normal practice when setting up a wifi network. It’s expected to have to do this level of network management.

Until the 15Pro/max apple users never had to deal with 160Mhz or DFS or AFC. The bandwidth was limited to 80Mhz and that meant no support for channels in the DFS spectrum.

I tested it one more time, and here are the results.

-- WIFI 6, Channel bandwidth: 160MHz, Connected successfully

-- WIFI 6e, Channel bandwidth: 80MHz, Connected successfully

-- WIFI 6e, Channel bandwidth: 160MHz, Can't connect or recognise the WIFI 6e SSID

-- WIFI 6e, Channel bandwidth: 20/40/80/160MHz, Can't connect or recognize the WIFI 6e

So iPhone 15 Pro Max can connect to both WIFI 6 and WIFI 6e SSIS, however, it can't connect to WIFI 6e when it is set to 160MHz. The connection is faster and more stable when connecting to wifi 6 at 160MHz compared to connecting to wifi 6e at 80MHz

I can’t tell what the connection speeds are as the iPhone doesn’t provide connection speed details in the settings. Android phone is doing much better in providing these details.

My husband just got an iPhone 15 pro max and is having the same issue. I have a 14 pro and just updated to ios17 and am now experiencing the same issue. Hopefully Apple fixes it with a software update soon
