iPhone 15 pro and pro max too slow on wifi connection

Sounds like it's an issue with your network. Are any other devices having Wi-Fi issues as well? Or is it just your iPhone 15s?

Thank you changing to a 2.4 htz WiFi network helped. I do agree though that the 15 Pro Max is slow. If Apple doesn’t issue a software fix I am going change back.

Did you go as far as restoring the phone using a Mac or PC, setting up as new and seeing if the issue persists?

If you did get that far, I'd contact Apple to have them run diagnostics on your device, it's just odd that two brand new devices would have the exact same issue.

all my apple devices other than 15pm work well with my home wifi.

the 15pm worked okay untill I took a trip and came back, then the network messes up-- either the cellular and wifi work properly, super slow and disconnects for the most of time.

-tried restart the device, not working

-reset network, not working eiterh

Yup.. same issue with me still.. but better in ios 17.4.. from old version…

my noted this issue appear if using multiple WiFi network on iPhone 15 pro max … if you saved any wifi network on your iPhone 15 should be deleted all .. and connected with one only … until apple fixed this problem 😔

im using iPhone since more thin 10 years maybe … im never see like this issue with any Apple device

Cooling Down the iPhone:

For a few hours, perform the following...

• Power Off: the iPhone for a bit
• Unplug: any Cables
• Place it Atop: a Laptop Cooler
• Keep it in: an open space
• Keep it Out of: direct sunlight

I found a solution for iPhone 15 super slow wifi.

I think the iPhone's problem is preferring for some reason 2,4 GHz over 5 GHz from your home modem.

New modems have usually band steering mode. This means your appliances can choose wifi frequencies automatically from your home wifi network.

2,4 GHz has a longer range and slower speed and it is compatible with most electronics

5 GHz shorter range and higher speed and for newer electronics

If we create 2 separate wifi one for 2,4 GHz and the other for 5 GHz, and let the iPhone connect to only 5 GHz, speeds go instantly higher.

• Find your home modem and connect to the admin page in your internet browser.
• You will find the address and password at the bottom of your modem
• The address is 192.168.x.x. In my case 192.168.0.1.
• In the admin console under WiFi, enable networks 2,4 GHz and 5 GHz
• Name them differently and apply changes
• In iPhone wifi settings ignore the old wifi network, and connect only to a 5 GHz network and that is it.

Video how to do it!

Turning off Private WiFi worked great for me. Go in to your network settings and turn off private Wi-Fi.

Have you tried Resetting Network Settings and connecting back to your Wi-Fi?

I switched from iPhone 13 Pro Max to iPhone 15 Pro, and it's frustrating how slow and useless the iPhone 15 is compared to the 13.

I had the same problem on my iPhone 15 Pro Max ios 17.3 when it connected to the Wi-Fi network.. I made a comparison with my old iphone X ios 16.7.5 same network

result :

Note : I have reset the network settings on my iPhone 15 Pro Max and the internet speed is now fast.. I do not know if the issue will return later.

not fixit…

My Temporary solution (reset network setting ) on iPhone settings

but will appear again after couple day you need repeated every time

Exact same issue. And yes I’ve tried all the suggestions. And no my phone isn’t overheating. Literally every other device on my network is still ok- including the 12 pro max I retuned that I’m starting to wish I kept.

i also had similar feelings going from 12 mini to 15 pro. It seems to me that 15 pro is not fast to show real time updates of weather using built on weather apps or live score of any match using browser.
