iPhone 15 Pro Max Wi-Fi Issues

I’m with Fibrus full fiber and it only does speeds up to 30/40 meg on my iPhone 15 pro max. I retested loads of times on my old iPhone SE and it gets speeds up to 300 no problem at all. Something really isn’t right

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.

Your comment ultimately fixed my problem. I went into VPN under settings and turned my status to “Not Connected”. My IPhone 15 Pro, that had previously refused to connect to my WiFi at all, immediately connected itself. I could cry, THANK YOU!

I wonder if we have the same issue. So my WiFi issue only occurs when I leave my house and come back, in that it won’t reconnect to my WiFi. It always says 5G+ and when I check the settings it’s not on my WiFi and I have to manually re-select my network name and it connects just fine then. Once I’m connected to my WiFi, it never drops or has issues, only when I leave the house again (like to walk my dog) and come back does it not reconnect so I have to manually click on it again.

Yes, I have it set to automatically connect. I’ve also reset my network settings on the phone and played around with my router as well. I have a high end Nighthawk router that runs a 6Ghz 6E band. Now the one “problem” I have (problem per apple but no other product I own) is that I name my 2.4, 5, and 6Ghz bands all differently (with the same password though). Apple wants me to rename all three bands to the same name to fix my connection to make it “stable”, but I won’t do that because then it’ll screw up my diverse band limited devices throughout my household and I don’t want my phone wanting to switch to a 2.4Ghz band just because the signal itself is marginally better at times. I did this kinda setup with the same network name and oh boy everything was messed up and my devices across the board were running slower. My iPhone XS never had this issue, even with bands named differently. I wonder if it’s something else.

The selling point is the ability to connect o 160 mhz. But everyone appears to be having issues connecting or staying connected. For some reason, my phone will initially work fine and speeds topping 1.4 gbps but after a while drops to below 50 mbps. I shouldn't have to change my WiFi 6e settings. Major bug.

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.

There are only 7 160Mhz channels added to wifi 6e support in the 15Pro/Max. AFC rules to kick you off the channel you are using must be followed.

Just as a test make sure you only setup a SSID that uses 80Mhz bandwidth in a non-DFS channel.

Setup your phone to only connect to this SSID. I know it is not what most of us expected from wifi 6e but those are the facts.

I have also many Wifi disconnections!

I put my phone on Airplane mode at home at after some minutes I lose wifi like it doesn’t exist. when i wake it up then after some minutes it restores.

My device is iphone 13 pro max with the final release and my wifi router is Linksys WHW03v2 operating wifi 5

Thanks for the input! What you explained is definitely how it’s supposed to work, but when I’ve changed my router and devices to work that way (especially my phone) I often find those devices switching to a different band, and pretty steathily I might add to a band that it shouldn’t theoretically switch to, and then I have to go manually change it back to the desired WiFi band as it won’t select the best band. I get what you are saying though as that is how the devices should operate and there shouldn’t be an issue (and in fact if it worked that way it would increase my overall connection/stability), I’ve just found in practice it doesn’t always work out that way. That’s why I force things to only connect to certain bands now so they “don’t get any ideas” and have a mind of their own haha.

That being said, so this morning when I woke up, I found that my phone was off the WiFi and connected to the 5G+ network instead. First time I’ve notice my phone just getting off the network while I never left my home. When I go to reconnect to the router, it shows full bars for reception. My condo is not big at all so I’m never more than like 20 feet from my router (with minimal

walls). For reference, I have a Nighthawk Raxe500. It has no connection issues with any other devices, including my laptop which is the only other device currently configured for the 6E band.

I had a similar experience today. I only get 2 bars on my phone network but got 4 bars and my WiFi connection completely disappeared in the corner. Then WiFi came back and my bars dropped back to 2 after a reset. Something is clearly going on.

I’m in agreement with you for now on the phone being the issue rather than the router itself. My old iPhone XS (yes I was a long holdout haha) worked great on this same router, even with just the 5Ghz band, and never had connection issues.

Do you have your network set up like mine with different names for the different bands or do you have one name for all three bands as Apple wants us to do?

A few notes that I have figured out here. First, many things you try at first seem like a fix, but the problem comes back, (restarting, disconnecting/reconnecting wifi, reset network settings etc). What I have researched and found to work is this. On my Asus AX88U running latest Merlin firmware, 2 things solved the issue.... 1) uncheck box to for 160hz. 2) Leave 160hz checked, but use the pull down and select only 160hz as the option. Right now Im doing the latter for maximum performance, but if I run into compat issues elsewhere I will go with the former. This looks like a software bug to me and an annoying one at that. For the record, Im also running latest iOS d3v release , and this issue is still present.

I have 3 SSIDs for 2.4GHz, 5GHz (WIFI 6), and 6GHz (WIFI 6E).

I can only see 2 SSIDs for WIFI 2.4GHz and WIFI 6 listed in my iPhone 15 Pro Max.

WIFI 6E SSIS is not listed or recognized.

Does iPhone 15 Pro Max support WIFI 6G?
