ios 11 slow wifi speeds

Didn’t work for me.

This absolutely worked for my phone and my wife’s. Good work Chaz!

Me? What did i do?

In sound options you can reenable the buttons...

I too I too have similar issues , just that it’s with my iPad

my android phone sitting practically next to the iPad clocks amazing download speed on same wifi.

Same here. Just ran test using Speedtest on my iPhone 6S and Samsung SM J327V.

iphone download 12 Mps, Samsung 60 mps. Crazy!!!

Glad it worked for you. I could try it with my home router but cant make changes with my office router.

So it’s still an unresolved issue for me.

Hi Leddra2k

Could you please tell me how you roll back to a previous IOS. As since I’ve updated my iPhone 6s to IOS 11.3 my WiFi as been rubbish.

Thanks Craigy72

It's not a bug. Apple clearly does this on purpose where they mess with your wifi connection. It's like that battery scandal thing all over again. Waiting for the class action.

iPhone 6S Plus, and iPad Air 2, with public beta of 11.1 i've started to get this issue on both devices.

I have a 400mbit connection on docsis3 at the moment, and 802.11ac on iMac 2017 model for example is pulling 45mbyte/sec, full connection speeds. speedtest (dot net) shows me 388mbit average of 15 tests within 1 hour.

The iOS devices usually were able to get around 300mbit in other rooms of the apartment. But no longer.

I am getting 40mbit is I am lucky. With the latest public beta 5 of iOS 11.1 i am however getting my upstream again. This was not getting over 15mbit, but now that's 40mbit again (upstream from ISP is 40mbit indeed).

But the downstream is 40mbit, not 400mbit.. a massive and obvious difference.

Over 4G+ I am getting between 60mbit to 100mbit, depending where I am in my concrete apartment. Outside it's a bit higher. 4G appears to be 'just fine'. The issue for me seems to be the WiFi.

I use 3 different speed test apps, 'network analysis', 'ookla speedtest' and a site in safari that lets you get 1000mb.bin files from various locations. The max I have had in over a month now is 44mbit. Resetting, restarting, restoring, etc. Nothing has helped.

Great discussion and suggestions, so far nothing has resulted in anything positive. Well, downgrading to 10.x worked (restoring backup). That restored it just fine. It's iOS 11 that gives me issues, especially 11.1.

*****..

so far so good.... after 11.1, when i open mail, I am able to push "mailboxes" and get INSTANT feedback...instead of the 3-5-10 second lag with 11.03

I will keep this thread updated. I am at work, so the real test comes when I get home on my 5g network

Hey guys, this might help solving the problem, i have tested it

When you are in ios 11, automatically when you start up your phone, the cellular data is turned on along with the Wifi connection,

in short, you just have to shut the cellular data off, the wifi speed did enhanced a lot. This helped me, but still wait and hope Apple fix this as soon as possible.

I tried "go to settings/general/reset/reset network settings" on my iPhone 6 iOS 11.0.2 and it did not work.

I also tried resetting router, modem, airplane mode on/off, wifi on/off, cellular data on/off, roaming on/off,... but no joy.

Same issue for iPad Air 2 11.0.2.

Before iOS 11 update I got 112Mbps on wifiAC/5GHz, after update 55-60Mbps.

I am not ready to wipe both devices back to factory new state.

MacBookPro on High Sierra 10.13 on same wifi network/router gets 112Mbps...so its not the wifi router/modem.

I believe I was getting 112 Mbps on iOS 11.0.0 (iPhone 6 and iPad Air 2) and slowdown to half speed happened with iOS 11.0.x update.

if i switch to 2.4GHz (wifi N?) I get the same (slower) speeds of 55-60 Mbps, which is normal for that wifi band for me.

MacBookPro on High Sierra 11.13 on same router ac/5GHz gets 112 Mbps.

Chaz,

Since I made the change in router putting my devices on static, outside the router’s DHCP pool, haven’t had issue in 3 days. When I spoke to an Apple rep awhile back, they recommended I try this as well. Don’t know why I didn’t try then. Think it was when I was swapping out my router/modem with cable company and forgot.

The static IP you set up is tied to the MAC address of the device. It’s possible the DHCP interactions with device cause a conflict. Might be worth trying on the one device you’re having issues with.
