Upgraded to an iPhone15 from an iPhone X (yes, really) and ever since the wifi connection is awful. Pages that loaded perfectly on the same WiFi with my iPhone X, will load very slow if at all. More often than not, I end up getting frustrated with the slowness that I just exit out of the app or site. It’s really bad and I’m not sure if this is a settings problem or if my WiFi chip might be defective??
iPhone 15 Pro Max, iOS 17
I just up graded to the 15 pro lase week and my wife to the 15 pro max this week and the down load speed is so slow on wifi that we have to stay on data.
is there a update coming?

Troubleshooting iPhone WiFi:
A few thoughts to try:
I. Start Here: If your iPhone, iPad, or iPod Touch won't Connect to a Wi-Fi Network - Apple Support
II. Clear the Temporary Internet Files:
III. Restart your Router:
IV. Reconnect to your Network:
V. Add Back the Network:
V. Reset All Network Settings to Default:
Example of items that will be reset: (Wi-Fi Passwords, VPN Connections, etc):
I’m not sure how adjusting settings for Safari would affect WiFi speeds on my phone in general but I gave you the benefit of the doubt and tried it. Maybe this helps in the Safari app itself but using chrome or running a speed test still has the same resulting slow speed
Yup it happens on every router/ wifi connection, so it’s not the router/modem. Hopefully apple will update something on it. Its horrible. Bout ready to toss this piece of **** in the garbage.
It won’t let me vote right now but that 👆🏼from JMAN712 did it for me! Thank you!
Is it possible that your router defaults to 2.4GHz not 5.0GHz? I had the same speed issue with my iPhone 15 but only at my house. Unbeknownst to me, my router flipped to 2.4GHz during a reset. Once back at 5.0GHz the problem was solved.
Turning off Apple iCloud+ Private Relay worked for me. It didn’t cause performance issues on my old iPhone 12 mini, but has done since I upgraded to an iPhone 15. Could be a coincidence as there have been reported issues with Private Relay recently (it is Apples version of VPN).
To turn off - Settings > Apple ID page (select your name at the top) > ICloud > go down to iCloud+ section > Private Relay > toggle off
Or just search Private Relay in settings and Bobs your uncle.
Soon as I made that change my internet browsing is instantly back to normal.
Id rather pay for Nord VPN for encryption rather than have performance issues from iCloud+ Private Relay.
Hi.
I had the same performance issue. I was using packetlosstest for diagnosis. I was loosing about 20% of traffic.
I started reviewing my router settings and I found MU-MIMO option.
When I disabled it then packetlosstest showed 0% loss.
It looks that iPhone 15 Pro Max is not compatible with MU-MIMO. I have Xiaomi Router Mi AIoT AC2350.

I was able to find a work around, but it’s a little disappointing that Apple couldn’t handle the load effectively.
For me, the work around was disabling the VPN option within Active Armor (ATT security app). Apparently, using Private Relay and a VPN was causing the slowness and/or timeouts in page loads. Disabling VPN seems to have resolved my page load problem, and I can still utilize Private Relay.
TBH, feels like a software problem that should be corrected in a later release. Why should someone need to turn off VPN just to get a decent page load time?
This is what worked for me. I have the 15pm
Disable Wi-Fi Assist: Wi-Fi Assist is a feature that automatically switches to cellular data when the WiFi signal is weak. However, this can sometimes lead to slower WiFi speeds. To disable it, go to Settings > Cellular and scroll down to find Wi-Fi Assist. Toggle it off.
Temporary fix. 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.
Hello,
If it worked at your house, but not when you left it, it could be an issue with cellular data. See this:
Use cellular data on your iPhone or iPad
View or change cellular data settings on iPhone
Good luck.
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.
My Download Speed is Fine but my YouTube Videos are loading years and get stuck throughout the Videos….
Turning private relay off returned my WiFi download reading speeds to normal.
My IPHONE 15 PRO MAX WIFI is painfully slow as well, turned off Cellular to try and make it faster along with several resets. This phone is trash. I upgraded my 13 and just want it back :(
iPhone 15 WiFi painfully slow.
