iPhone 15 Pro Max Wi-Fi Issues

reseting network not fix my problem, unfortunately.

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 phoned Apple support for this same issue today and they had me reset network settings. Worked fine after that for about 4 hours then crept back up again. Have ASUS GT-AX11000 and RT-AX88U mesh setup running separate 5 and 2.4 SSIDs. I just favored the 2.4 and will see how that goes for the evening.

Update - I've troubleshooted through some suggestions of changing the wifi channel and bandwidth and nothing really worked. As a last ditch effort, I dug out an old TP-Link RE230 wifi range extender to test it out. I set it up both as a range extender (picks up existing wifi and extends it) and access point mode (connects to existing wired network and change to wireless) and my iPhone was able to connect to the 5ghz wifi with internet on either! The speed is not the best, but good enough. I'm getting 30Mpbs down/25 up on 2.4ghz wifi. And 93down/93up on 5ghz wifi. I'm not sure if the iPhone 15 have a new wifi chip/modem that's having trouble with some manufacturer's routers. I wouldn't call this a complete success because it should just work out the box, but it's better than nothing.

I suspect the problem will return for you but please keep us posted here. I want to make sure this is something that can be fixed via software update before I decide to keep this phone. I have reset everything and updated the firmware on the router etc and it's still an issue and ONLY with this phone.

So I disabled the 160mHz frequency on the router and that seems to have made this problem better but the max speed near the router has certainly dropped. This is just not an acceptable solution given this is the PRO phone and obviously should not have this compatibility problem. Will keep you guys posted here as I have another router coming in that is quad band and can push a 320mHz signal (yes yes I know the 15 pro max isn't wifi 7 but the theory is that if it can sit on it's own 6E radio that may be enough to solve this problem).

Having same issues disconnected all my other devices from 5ghz WiFi and then magically iPhone 15 pro max was working great and fast. But then turn on say PS5 iPhone immediately disconnects connection issues. Probably my router apartment complex uses old router technology.

Same. I haven't had this issue with past iPhones. I found it weird (and frustrating) that my old iPhone, all my other devices and everyone else in my house's devices worked fine, including my dad's new phone (not Apple). I hope it's not a hardware issue too. I hope this is something they can fix soon.

I'm not a behind-the-scenes computer person, so I don't understand the different hz, routers, etc. I've either been using the 5G (I think, I don't understand that either, but that's what I see on my phone) data or sometimes wifi (at home) when it works or another device.

I'm also very glad this issue isn't only happening to me.

Maybe this helps. So was able to try 5Ghz WiFi at someone else’s house worked fine with new iPhone 15 Pro Max they had multiple devices connected Samsung Phone and Smart Devices Alexa, etc. Leads me to believe it’s my out dated router and ISP (CenturyLink). If I disconnect everything at home then it works as expected or better but the minute I connect another phone or game console to 5Ghz again no internet connection , disconnect everything and then iPhone 15 Pro Max works and speed is good. Makes me think it’s not a hardware issue based on what I have seen.

I too am having issues with the 5ghz, the actual internet works fine for all my other apple products, so it isn’t the internet. However since there is such a limited number of available of phones I really hope this isn’t a hardware issue because a replacement will take 1-2 months from what I was told

Yeah. Especially since it's so many people having the same issue. Like we're not all on the same Wi-Fi network/using the same routers and different internet providers. All other of our devices and others in our household work fine. The common denominator is Apple, iPhone 15s.

I really really hope it's a software issue because that can be fixed faster/sooner. I'd love not to have to get a new phone.

Yeah I was going to trade in my iPhone 14 Pro Max but now not so sure I should in case the new phone completely doesn’t connect one day. Has anyone seen any news on the issues? Checked earlier and nothing but have seen lots of forum discussions like this one here and on Reddit, MacRumors etc

I think I've isolated a fix (albeit more of an annoying workaround) for the issue. For some reason it was just my home wifi not working with my 15 Pro so I created a Guest wifi network through my ISP and my phone is able to connect to that one even though it's the same router. Really bizarre but it's been three days or so now and it's still going strong. So we'll see.

Same issue for me I’ve tried resetting the networks resetting the router resetting the whole entire phone no matter what I do the Wi-Fi cuts out every few minutes or sometimes I’ll be doing a Speedtest and I’m getting 600 MB per second but can’t load a simple video makes no sense! Very frustrating for a $1200 phone Apple needs to fix this never thought I would say this, but this is starting to feel like a Samsung Galaxy operating system.

I'm also have an issue with WiFi, at home I'm using Zyxel c2100z router from Century Link. I'm using only 5Ghz, as it's provide better speed and less interference. My current settings was at 48 Hz (for Nintendo Switch from different country that doesn't support 140-160 Hz), my iPhone 15 Pro could connect to the network, but internet either not working at all, or it's very slow (usually it doesn't work at all). Tried to change it to 44 and to 160 Hz, doesn't change anything.

I don't have problems with any other devices.
