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 don't think it's a WPA2 issue, I've always had my router set to WPA2-PSK [AES]. Done full resets of the router (R7000) and modem. Occasionally the Wifi improves for a short time but then dies again. While I don't fully trust either the Netgear router to be the culprit since it has had it's issues, I have an iPhone 5 and an iPad, both on iOS8, and a MacBook all able to connect on this network and get great Speedtest results, whereas the iPhone 6 has extremely slow connections on this network.

Same here, really glad that I found this post (iphone 6 not working with otherwise perfectly working Wifi). Traded in iphone 5 worked perfectly with good Wifi speeds (iOS 7). Brand new iphone 6 barely could do audio, incredibly slow Wifi.


I have stayed with WEP because of a legacy Roku radio box that cannot do WPA2.


For me, the only thing that worked was changing the router over to WPA2, Success!


Looks like for whatever reason, iOS8 and/or iphone 6s do not work with legacy WEP router settings.

I'm having trouble with wifi as well. It seems like the act of connecting my iPhone to wife is causing the router's wifi signal to crash - all other devices in my house lose wifi when I try to connect to the wireless signal.


I've tried messing around with every combination of 802.11 signal and security keys and it still just dumps me into LTE every time I try to surf the web or download from the App Store over wifi.


Been working on this for hours now and haven't come up with the magical router setting, including firewall settings.

I went to a Starbucks and connected to wifi there. No issues. Video and surfing was fast and smooth with no interruptions. That convinced me that it is my router. I went home and played around with the security settings. Was fine on WPA2, but still problems on WEP. Suck. I have one device that still uses WEP, and does not support WPA2. I guess now is the time to upgrade that dinosaur of a wireless bridge. Still, Apple needs to fix the WEP bug.

Okay, I'm now starting to think this is a problem with iOS 8's ability to talk to my router. My mom's iPad Air on iOS 8 is having the same wifi problems as my iPhone 6. My iPod Touch 5 on iOS 7.1.2 downloads using that router just fine.


This is pure speculation, but this may be a problem with the way iOS 8 randomizes its MAC address when connecting to networks. Remember that was a new feature added to iOS 8?

**Changing my router settings to WPA2 solved my issue.

Situation recap:

Since purchasing my iPhone 6 64 GB AT&T on launch day, I had a very slow connection speed on my home Wi-Fi network. I was able to connect to my Wi-Fi network, however, the connection was quite poor (download speed averaged .01 - .56 Mbps). This is not my first rodeo (or iPhone for that matter) so I attempted to resolve it myself by: restoring from an iCloud backup (twice), restoring as a new device from iCloud (twice), hard reset numerous times (holding home button and power button at same time), resetting network settings, resetting all settings, etc.

I finally called Apple today and spoke with a rep who was of no help (she concluded that my slow connection was due to the Wi-Fi calling feature not being supported by AT&T until early 2015). My second conversation with a rep ran diagnostics and she stated my phone's Wi-Fi was labeled as normal or that it "passed" its test. She transferred me to a senior rep and he wanted me to restore my phone (again), but through iTunes this time. If that did not fix my issue, then visit a local Apple Store or send my phone to Apple to be tested. After ending our phone call and at the start of attempting to restore my phone via iTunes, I came across this discussion page. Changed my router's settings (Linksys router) from WEP to WPA2. It has been roughly 30 minutes since then and my Wi-Fi connection is flawless.

Thank you, guys!

P.S. the last Apple rep I spoke with gave me his office number and I called to leave a voicemail about the WPA2 solution. Hope this gets resolved for others!

what wifi router are you using?


I'm running Netgear 300, it's on the older side now, but can do 300 MB with TimeWarner ~25 MB service, seeing 10 to 20 MB on iphone 6 now with speedtest since I went over to WPA2 from WEP.


I did the network reset thing (actually a whole phone wipe too, because I earlier did a restore from my iphone 5 iOS7 backup, just incase) while still on WEP, none of those helped.


I resurrected an ancient linksys WRT54G to provide WEP for my old favorite Roku M1000 sound bridge Internet radio "tuner". They promised WPA, but never got to it before they abandoned the sound bridge products in favor of the video products.

Having the same issue. Went to the Apple Store and got the phone replaced, but still getting same issues. This is only happening with my home's Wi-Fi, Apple Store's Wi-Fi worked fine, all my other devices work fine, so this tells it's either the router or an iOS issue. I'll try tinkering with my router tomorrow and will report back.
