Internet speed slow down after IOS 17.1 update

I was very sceptical about doing any further upgrades until this week when I had to make a decision about upgrading after having major issues after my last upgrade slowing down my iPhone 13 Pro, I did everything suggested to help speed it up.

I now have done the upgrade 17.4 and fine my iPhone has the speed back. They have obviously rectified the previous issues, with new additions which I’ve not explored yet, things seem to be getting brighter.

My wifi picked up a lil more speed after I turned on the private relay , it was already off for me

was facing the problem with ios 17.4.1

Have updated to 17.5.1 , looks like fixed the problem.

updating from ios 17.4.1 to 17.5.1 solved the issue for me

This is a user forum. No one here is getting paid. On the other hand, some very experienced folks (not me) take the time to help out.

I’m also having this issue on 17.3.1 with my iPhone 15 Pro. Knowing that I hadn’t turned on my current gen iPad Mini in awhile I booted it up and ran a test since it was on 17.2. It got 500mbps. I then updated the iPad to 17.4.1. My iPad now only gets 40mpbs down. I took screen recordings of both of those runs. In both cases the devices have iCloud relay off, and I disabled background app refresh for all apps to see if that mattered. No change for either. Resetting network settings also had no effect. My work laptop and phone(Windows and Android), both easily get 800-900mbps down on the same WiFi network. My iPhone 15 Pro also gets 900mbps down from its cellular connection through t-mobile. The issue only presents on my iOS devices with current versions of iOS, and only on WiFi.

This is a disappointing response. Nothing changed in my environment but the update to 17.1.1. All my Apple devices are now slow, particularly loading safari web pages. All my other windows devices are running at typical speeds. The suggestions above are standard recommendations to avoid doing the real work to identify and fix this. I see significant chatter on this so it’s not just me and my network.

I would appreciate more testing and analysis rather than blowing this off with the usual canned response.

After updating 17.1.1 my iphone 13’s wifi speed has slowed down drastically. Youtube, facebook and even the safari browser is taking long time to load and display content. Because of the lag, the phone is continuously switching to mobile data from wifi. Just to clarify my wifi is working fine with other devices. Please fix this as we expect premium products and services from apple

I am facing the same issue as you.

My wifi speed is perfectly normal (my other devices are working normally) but when I use any application on my iPhone 13, the content takes a lot of time to load, this is unusual behavior. In fact, just the other day I was trying to upload a file (5 MB) and it took around 3 minutes just to upload this alone.

I have been noticing this with the iOS 17.1.1 update.

Any way to fix this? This is absolutely frustrating and makes the mobile impossible to use!

Running into the same issue running iOS 17.2.1. Tried all basic troubleshooting (restarting modem/router, restarting iPhone, forgetting/rejoining network) and still the problem persists. Download speeds for non iOS devices are >500 mbps, but getting <10 on my phone. Even turned off private relay. No luck.

My Previous comment was that my problem was solved by deleting the Microsoft Defender app. I just reinstall the Defender app, and everything seems fine. I don’t know why.

Been there. Done that.

Both of my replies are simplistic and for starters. Having no success, move a bit forward with the following reply by @iagastya. Any success?

That text book troubleshooting, this has to do with IOS 17! After this update surfing the net lagged big time get a message sometimes saying reduce protections to load page or something.

I have an iPhone 13 Pro and my internet speed has slowed to the point it is almost unusable after the latest iOS update . Occasionally it will work when connected to WiFi but over all it’s terrible . I’ve done all

of the usual resets and bug fixes for typical issues with iPhones to no avail . Please fix this Apple.

Mine is the same super slow if you search this issue it’s all over the internet. Apple has no intention on fixing this issue. Was told by apple I might need to upgrade my iPhone 12. Lmao bout to switch over.
