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
Ooooh!
I found it.
I thought I was going crazy or it was wifi 6E or just a flakey connection.
Settings>Safari>Advanced>Advanced Tracking and Protection Fingerprinting Protection.
Turn this off.
I toggled it back and forth and it's night and day.
This 100% solved it for me.
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?
I don’t know how you found this seemingly obscure setting or how anything to do with Safari affects WiFi speed, but I toggled this off on my 15 Pro and the difference was indeed night and day. From d/l around 114 Mbps to 457Mbps, and upload from less than 1 to over 40 Mbps, so thanks for that! Cheers.
I had the same problem. After multiple calls to Cox it was revealed that my router (PW8, Brand: TECHNICOLOR
Model: CGM4981COM) defaulted to 2.4 GHz when I set up the network. I set up another network at 5.0 GHz. Problem solved. This is how I checked on my MacBook Air-Click on the WiFi icon in the top nav bar while holding down the Option/Alt key. 3. Look at the channel information written in grey text. It will say 5 GHz or 2.4 GHz.
Interesting. I recently upgraded from an iPhone 12 to an iPhone 15 Pro Max.
I had this problem recently with my old iPhone 12, and just assumed that my old iPhone was nearing the end of its useful life (the battery was also not lasting as long as it used to), so a possible ageing hardware issue. I never got to the bottom of this, as I planned to upgrade, which I assumed would cause the slowness issue to disappear.
Not so: the new phone suffered from the same problem, so I came here for advice, and tried every suggestion - all to no avail.
Having exhausted every possibility, I took the problem to an Apple guru in the Genius Bar of my local Apple store. He had not seen this before, and tried all the (to him) obvious tricks to increase the speed without success, then he stripped everything off my phone and completely reinstalled the iOS - which worked properly straightaway. My phone is now operating at maximum possible speed, both on WiFi and data.
We still don’t know what the problem was, but the reinstallation of the OS certainly solved it so it is presumably software-related, especially as it also occurred on my old iPhone 12.
And restart your iPhone. Also, mine appeared to already be set to not connect, but it was also using my password manager VPN. Dashlane doesn’t have this setting, so I changed it to another VPN and then set that one to not connect on demand. Restarted the phone and the speed is back to normal.
I had a similar issue when I got my new iPad which uses the same technology as the iPhone 15 Pro does. It may have something to do with WiFi 6E. You can try to turn off the WiFi 6E and see if this makes a difference for you. Goto Settings > WiFi and click on the blue “i” on the side of the WiFi that you are connected to. Once you’re in there you can find WiFi 6E and select it from automatic to off and see if this makes a difference for you. It made all the difference in the world on my iPad. That being said, it wasn’t the iPad itself, it was most likely a setting or something in my router that didn’t work well with the iPad but did with other devices as the WiFi 6E works fine with other routers. My router was included with my Xfinity Internet and just didn’t play nice. I have since moved and use a different provider and their router works fine with the WiFi 6E. I don’t know what it was with that router and other routers by them as well but when I left it works fine with the new one that I have with the different provider so I was never able to see what would happen when I got the iPhone 15 Pro Max because I was out of there by then, but I can tell you that I did see that with guests that had the iPhone 15 Pro when they would come over their phone would do the same thing and turning off this setting it worked fine.
I 100% agree with you. I am doing the same thing so frustrated that I just don’t even try to access the website. I went from a basic iPhone to the iPhone 15 and I am very very very disappointed. Maybe I should change to an android, my son says they’re great.
OK everyone, I tried every suggestion in this post. I finally though fixed it.
go to Settings
click Wi-fi
Choose the network you are using and hit the blue i circle on the right
If you have Private Wi-fi Address "on", shut it off...wait a minute, click it back on.
BOOM - worked amazing for a while, then slowly it crept back to crap again.
Back to the drawing board.
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.
Have exactly the same issue
My Download Speed is Fine but my YouTube Videos are loading years and get stuck throughout the Videos….
Hello JMAN712,
Thanks for the update 😀
This didn't change speeds for me
You are a superstar!
Same problem and the solution was adjusting the router. The network was mistakenly set at 2.4 GHz. When I reset to 5.0GHz the problem was solved.
iPhone 15 WiFi painfully slow.
