Slow wifi in iOS 8?

seansed said:
My router only runs at 2.4ghz and I have tried changing the security settings to every option available (has always been WPA2) and nothing has changed. My d/l speed always stays around 1.5-2Mb/s when it should be around 15-20Mb/s. I've changed channels, wireless names, security settings, and distances and nothing makes a difference. Again, my wife's iphone 5 and my ipad, both not on ios 8, have normal wifi speeds.

How many other WiFi networks are in your area? I've found that iOS 8.x isn't as good as handling interference as iOS 7.1.x was. If there are a lot of networks, your performance can suffer. A way of testing this is to run speed tests when next to your router. If the speeds are still bad, I'd try swapping devices.
 
Bluetooth impacts wifi speed on 8.1.1

I'm on 8.1.1 on a 5s. 8.1.1 is better than 8.1, but wifi is still slow when I'm at home.

I've noticed that Bluetooth enabled has a huge (10 Mbps) impact when I'm at home. Off 12 to 18 Mbps and stable, on 1 to 3 mbps and dropping slower over a minute.

When I'm at work wifi is very fast 50 Mbps. But some experimentation showed that Bluetooth still affected it, but not by as much.

One big difference between home and work is that I have 5 bars lte (in office repeater) and at home I'm in a shadow and get just 2 bars. I'm starting to wonder if the wifi/ip/Bluetooth stack is trying to find a better connection and that's causing the issue.

Also at home there are lots of neighbouring wifi networks, but those don't effect iPad or android wifi speeds.

For now, 8.1.1 with Bluetooth off works ok at home. Before 8.0 everything was good, 5s got same speeds as android devices at home and work.

Wish Apple would address.

Oh man, I want to thank you profusely for telling me about this. I had the same problem as you did. My wifi would start fast when I first joined my network and then degrade with half the speeds that I should get. I always left Bluetooth on and never thought about turning it off.

I tried everything that I know to fix this problem and swapped a new router instead of the old one. But nothing worked. I also had my phone jail broken and did not want to risk upgrading to 8.1.1 and still have this problem.

So I turned off Bluetooth last night and BAM I had consistent speeds of 39-40 Mbps.

There is indeed some interference between wifi and Bluetooth.

Once again thank you so much for suggesting this.
 
Fixed by Swapping for New IPad Air 2

New iPad Air 2 was getting 2 Mbps over my home wifi. Swapped older FIOS wifi router for new gateway router. Same thing. Old iPad Air with IOS 7 downloaded at 80 Mbps. iPhone 6 plus was fine, not slow. Wifi at Apple store was 60 Mbps. But Apple Store let me swap out my month old iPad Air 2 for new one. Got home and it's perfect. Solid 60-80 Mbps at all times. So maybe some iPad Air 2s have hardware issue?

Anyone having these issues in 8.2?

Extremily slow wifi sync'ing since I updated to 8.2 this morning.
Oh well, my MBP on Mavericks isn't any better - turn wifi OFF/ON sometimes helps.
I'm really running out of patience with :apple: :mad:

=== UPDATE ===

This worked for me now.
This will work next time.
Honestly, if it weren't for a few killer iOS apps (3rd party!) I'm kind of depending on, I'd go out shopping right now - instead of spending my time downgrading my iOS devices.

Wireless connectivity has never been one of Apples strengths. No matter if it's a Mac laptop or pad or phone. Some work ok, some not, none are ever excellent. That's from a guy that always has the latest devices and computers from Apple. In combination with a very robust wireless network at both home and work where we have 15 buildings with the finest networks money can buy.

Nor has any Cloud service they ever tried to launch. Why is that, I wonder?

It's got to be a priority issue, with all the technical expertise they have on hand I honestly don't believe they're doing their best work. It is puzzling that Apple would allow this well documented problem to exist on some laptops, phones and pads for several years. I replace my fully optioned top of the line customized to order MacBook Pro annually with the latest model.

Primarily because I enjoy getting a fresh new laptop, partially because my work demands lots of memory in the fastest possible configuration, and finally simply because I can. Over the last six years three out of the six had poor WiFi performance. One of which Apple replaced three times and the final one was poor, but at least it could hold a signal.

Concurrently each of these years I'm also buying workstation class ThinkPads. Everyone of which demonstrated flawless WiFi performance... :)

For a company who's second word in just about any sentence is "share", one would expect connectivity to be it's number one priority :rolleyes:
 
Should I update to iOS8.2 ?

I'm using an iPhone 5S and my phone is working fine.

I understand this iOS8.2 update is more for iPhone 6 owners who might also own an Apple Watch.

Since I neither own an iPhone 6 nor Apple Watch, should I just skip this update and future updates from here on?

Any replies will be very much appreciated. Thank you.
