iPhone 15 Pro Max Wi-Fi Issues

Update: My 15 Pro Max is still working great so far. Just got off the phone with Apple support and it was a cool experience sharing the screen and explaining what happened in detail. The support agent was very good. I finally had some time to do that and they happened to call at the prefect time. My frustration is gone now because everything is working so that helps. But next time I try to make changes to my mesh network from the 15 Pro Max Deco app while also using the wifi network simultaneously, if it does not work again I'll call them so the can collect logs and maybe that will help them figure it out. I just hope it's a software issue and not a hardware issue, or maybe a hardware issue that can be fixed/ patched with software updates (kinda like the Hubble Space Telescope mirror). Overall this a great phone and wifi works great for me now, but I don't have wifi 6.

I have ASUS AX89X and iPhone 15Pro.

My issues is not on the connection drop side but wifi uploads are being capped at 175mbps. Downloads are at ~800mbps from my Google fiber.

If I disable “Auto select channel including DFS channels” my download AND uploads go back to ~500mbps.

I really wonder what might be going on here?

Ok, I've been living with my guest wifi on 2.4ghz for a whole week because my home wifi on 5ghz just won't stay connected whenever I can get on it to begin with. Really disappointed. Apple has tried to reach out to me but with work and family, I just don't have the time. I'm returning it to the store this week.

I had this same issue when trying to set up my new Iphone 15pro from my old iphone. Basically after hours of troubleshotting we figured out that the issue was one VPN app installed on my old device which was blocking network connection when I trying to install in the new phone. Try to look at your app library in the new phone and delete any VPN apps or some that may have this capability like Google One. Also look under settings if your phone says connecting to VPN.

I was having the same issue and reading through all of these replies. Got to this one and checked my VPN. As soon as I looked at the VPN, I saw the slide button toggling on and off by itself. I removed the VPN and my phone immediately connected to the WiFi with no problems. I have Norton. I’m gonna message them with a heads-up in case there’s a fix on their end.

Resetting network settings in device was a temporary fix. Router restart solved nothing.

Issue resumed after leaving my house and returning to WiFi range.

absolutely horrendous performance. Cannot even load a song in apple music.

I'm concerned that my Amazon Echo has better streaming performance than my 1500$ iPhone.

Having the same issues, on multiple networks (not just home, places I cannot go configure.) I took it into the Apple store, and the employee told me to delete VPN apps, saying it will definitely work. It did not. I am incredibly frustrated and am trying everything in this thread.

Well I did what I swore I wouldn’t and had Bell upgrade my router. Had to upgrade my service level to get the new router but whatever. Absolute nonsense I had to do this just for consistent wifi in my house with one single phone (15 Pro Max) vs the 10+ Apple devices that worked fine. Apple continues to each out for logs (thanks Tracey!!) and I appreciate that but wow, no WAY we should need to do this for basic wifi connectivity.

Yes, that's the only network I've had success with (have only tried a few since activating the phone a few days ago).

I did finally get connected to my -5g network, with a solid speed test, while on the phone/screenshare with support. 10 mins after the call, everything regressed to exactly how it had been before. So, it seems when Apple is looking, the phone plays nice lol

I’ve tried disabling the icloud keychain, VPN removal, reset network. All of my other devices have steady full signal but it is only my phone that drops signal every few seconds.

the only time I have full signal strength is when I am next to the router.

have the same Asus router setup with Ai Mesh and having the same issues. no resolution just found yet. iPhone 14Pro Max on same network has no issues along with 20 other smart home devices. only my iPhone 15 Pro. seems to sometimes disconnect when switch ai mesh nodes or leaving the house for a few hours.

immediately noticed the same issue after upgrading to 15 pro max from the 13 pro max. First experienced watching Facebook videos and it kept freezing. Never had this issue on the same wifi with my 13.

Same issue here. I have an Iphone 12 Pro max, no issues. I've also recently had a Z fold4, no issues. but since I've gotten the Iphone 15 (pro max). lots of connection issues. I have no connection/internet issues with all other computers/devices on the network (including Ipad).

I also have an Asus Router. (AX88U). and I also had 160MHZ turned on. I have just turned it off to see if that helps.

One last bit. Asus just released a new Firmware. but the update had no effect on the issues.

I just got my iPhone 15 pro max today and the wifi speeds are horrible. My tablet and other phone is showing speeds in the 500mbps but the iPhone 15 pro max is maybe 150. There is def an issue with the iP15's hardware based on everyone's issues posting here and across the internet.

I’m having the same issue with my 15 Pro Max on iOS 17.0.3. I have the xFi Gateway latest model and 1.2GBPS package. All other devices: iPads, Apple TV, iPhone 14 Pro Max have zero issues with the network. Multiple times a day I lose a connection, won’t get iMessages, won’t send iMessages, won’t update apps and mail says ‘no connection’.

To be fair, I have really poor cellular service on AT&T in an urban area down a hill (usually 1 bar). The WiFi should not be impacted by this, however. Not sure what to do, reset the router, restored the device as new to no resolve. Hoping iOS 17.1 maybe has a fix as it appears to be a software issue. The speed and ping is terrible, we are talking slower than 56k dialup, lots of jitter. It did not start for me until ios 17.0.3 was released. I had the ios 17 beta all summer, but that was on the iphone 14 Pro Max, so it seems specific to the 15 models for some reason. Contacting both Apple and Xfinity and exhausted all steps. Did some DNS and configuration work on the modem in advanced settings as well.
