Slow Wifi on iPhone 6 Plus

Anyone experiencing really slow WiFi on their new iPhone 6 Plus? Mine is super slow. When I switch off WiFi, LTE works perfectly and very snappy. I didn't have any issues with my 5s and not having issues with my iPad Air. I doubt it's an iOS 8 issue because the 5s and iPad Air are running iOS 8. WiFi also works fine on my 13" MacBook Pro Retina. It's not a router issue. Any ideas??

I was having incredibly slow wifi response on my 64g iPhone 6. I did not think it was an iOS 8.0.2 problem because we also have an iPhone 4s and 2 iPad minis that were updated to 8.0.2 and they were not affected. It was just my new iPhone 6. I called Apple Support today and they admitted there is a problem with iPhone 6 and WEP encryption. His exact words were the iPhone 6 doesn't 'play nice' with WEP. After changing my router setting from WEP to WPA, wifi on the 6 seems to be working just fine. I will reserve judgement since it's only been a couple of hours but the Apple Support rep seemed confident this was a known issue and that changing the setting would work. I hope that helps someone.

Same as everyone else, so yesterday I just reset my network settings on the iPhone 6 Plus (my iPad Air was working fine). I left my router with WEP and I noticed some improvement. My router isn't new but it's not old either. Today, without further changes, I noticed that my iPhone seems to be flying on wifi. I wonder if anyone else has had the same experience. I remember one day a few years ago when almost all iPhones couldn't connect to wifi due to a problem with Apple servers. I wonder if they haven't changed something on their end. They'll never admit it but has anyone else noticed an improvement today? I hope it lasts but I'm not betting the house on it.

I'd be interested to know your timing today because until I made the change to WPA around noon eastern time, my wifi was still very slow. I had tried everything over that last couple of days before making that change and had noticed when I reset network settings my wifi was OK for a while. Wondering if that could be what you're experiencing.

So I just got my IPhone 6 and noticed that wifi would degrade from 20x5 to 1.5 x .68 or so after a few minutes. My LG G3 Android always got 20x5 or so no matter what the security encryption setting was. There is something effed up with either the wireless radio firmware or chipset itself on the IPhone 6. Changing from WEP to WPA tends to fix the problem which is odd.

On IOS 8.0 since new with iPhone 6+ got between 100 and 125 Mb per second on IOS 8.0 had no issues, resisted upgrading to 8.02, just went from 8.0 to 8.1 I'm very unhappy, latency is in the triple digits and downloads are .02 to .1 Mb per second. Not quite sure what the fix is, posting here hoping for an answer.


Same issue across iPad mini retina, iPhone 5, iPad 4, all of which are on IOS 8.0.

I have done a reset all network settings on all devices and no fix.


The only thing that has changed since yesterday that I can think that might affect it is Keychain or passbook. How does either of these things affect Wi-Fi downloads? 4G/LTE are all where they are supposed to be (8-24 Mb/sec).


This is all on a 6th generation Apple Airport router A/C/N, which I have restarted and reset and still slow WiFi on iOS devices. Two Macbook Airs and iMac are all 100+ Mb on WiFi.
