ios 11 slow wifi speeds

what settings did you leave the Cellular roaming data at? did you enable Voice and Data?

I honestly think that its what you said, that Cellular or LTE and wifi are fighting one another, not knowing who is in control..

I performed your steps and it does seem snappier...I will know when i get to my home network, were there are limited number connections

Roaming Off. Voice & Data On. I’m on a home network as well. Let me know how it goes on your home network.

My 7 Plus seems solid. I‘m trying to determine if wife’s 6 Plus is okay. Still testing.

I’ve reported this bug several times to Apple, with diagnostic logs.

It may be slightly better but the speed is noticeably slower than my wife’s 6. Sage phone

Def something to do with the speed in which the WiFi connects.

I will admit my phone has much more use than my wife’s. She is mainly on her iPad.

Also, why can’t I scroll the mail while it’s trying to connect? It doesn’t become live for 8 seconds

After plenty of testing, iPads (Air 2 / 10.5), iPhone 7 Plus (after reset all settings) are working fine on WiFi.

6 Plus is erratic on WiFi. Seems keychain is messed up between the 6 Plus and the Air 2, which are linked via wife’s iCloud account. I’ve reset her phone and no luck. Just so weird. Hit or miss. Sometimes gets consistent speeds, then reverts back to getting lousy speeds. Has to be some conflict in software. Just will have to be patient for fix.

But what software is different between the 6 and the 7 phones? It has to be a wifi driver right? Or the older wifi chip software... I wonder which wifi chip we have, the qualcom or the other one...forgot which manufacturer.

I have the Qualcomm on my 7 Plus.

All I know is, on iOS 10 the 6 Plus got full WiFi speeds consistentry. It can get full speeds at times now, but seems to revert to slower speeds for some unknown reason. Something is conflicting. I’ve done everything, including replacing router/modem.

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 will try that but that’s not a real world setting. To have to toggle that every time I leave a hot spot is unreasonable.

It’s not handing off....

Hey I wonder if handoff has something to do with it

I’ll try this later on my wife’s 6 Plus, but you’re right not a real world setting.

It’s odd that my 7 Plus is fine now after resetting it. The 6 Plus, even after reset, no go. Going to keep messing with it tonight, but has to be software related. Never happened on iOS 10.

Hi. JUST noticed as well my WiFi speed on iPhone 7 went from 360mb to 50mb after installing iOS 11, turning cellular off sorts the problem but shouldn’t be like that. Has anyone let apple know about that issue?

I can confirm that turning off cellular data makes the mail app more responsive from the start. I can scroll the already loaded emails while it checks in the background.

It’s still rather slow checking. Let me check with speeed test and also my wife’s phone

I have some of the same issues.

IPhone 8, 256 gb.

Use airport extreme and expanding Wi-Fi with the latest airport express.

When I'm closest to the extreme I have around 140 Mbps. When I'm closest to the express I have around 45 Mbps.

When I go back to the extreme I still have around 45 Mbps.

If I toggle the Wi-Fi off and on again in the iPhone, I get around 140 Mbps on the extreme.

It's even worse on my iPad air.

Anyone know how to tell WHICH WiFi chip we have in our devices?

My wife’s white iPhone 6 works perfectly while my black iPhone 6 chugs. They both have over 4gigs free. Both on ATT but that shouldn’t matter on WiFi

I tired that with no luck

BUT wiping my phone and restoring it from backup DID solve my WiFi slow problem in mail. Let’s see if it stays that way

I just updated my wife’s iPad Air and now it’s laggy only on mail also. I might wipe that also.

Something is not installing correctly

You wrote “Plus one thing that really annoys me! Is the volume rockers now control the volume on the media and not your ringer!!! Which is really annoying!!!”

This is an easy fix.

Go to settings, click on Sounds and Haptics, find the Change with Buttons switch, and turn it on.
