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??

Hi andrewfinance,


It really depends on what router/modem you have from Xfinity. Attached is
screenshot of their most commonly used router/modem provided by them. After you
access it, the interface should show you all the different security options
such as WPA, WPA2, etc.. Not familiar with their interface but this should get
you close. Worst case scenario is you might have to pain your way through a
support call with them
😢 Good Luck!

I really think it has more to do with the WiFi chip in the iPhone6.


As stated, 5GHz works just fine for me, but 2.4GHz is flaky. I have a dual-band router and it's always 2.4 that causes the problem.


I spent the weekend at my girlfriend's house and had the exact same issues on her Windstream supplied 2.4GHz G-band router.

It's definitely something with the 2.4GHz band on the iPhone6. WEP/WPA has nothing to do with it. It turned off ALL security and had all the same failure patterns. I also noticed it happens more under load when the phone warms up... tested by downloading keynote/pages/numbers from the iTunes store to stress the receiver.

II'm having the same issue, even with iPad Air since I upgraded to ios8. I have a new router already setup for WPA2. Nighthawk X6. My iPad Air, I was getting 160Mbps on iOS 7, now since ios8 it's crawling and disconnecting. I switched to the 2.4ghz and have had a relatively good connection but slow. I feel it's an iOS issue that I'm hoping they fix soon!

I had really bad download speeds on my iPhone 6. The switch to WPA2 helped me. Thanks guys!!!


I have an iPhone 6 model 1549 and a Verizon FIOS router. Download speeds were dismal. Upload speeds were ok. A reset of iPhone network settings would solve the problem for a very short time. So would a simple off/on reboot of the iPhone. After several days I switched the router from WEP to WPA2 and that seems to have solved the issue.


my iPad mini on iOS 8 was not affected before or after. Model A1489.

OOk here is my findings. I went to see s genius at the Apple Store and he tested my wifi equipment on my iPad and it came out to be fine. His findings was the software related and I should restore with iTunes and start fresh. After restoring from iTunes, Wi-Fi worked for two days without any issue. I restored the iPad but this time I used my back for all my settings and apps. No issues since been okay. I think it's software when downloading must of gotten corrupted and interfered in the Wi-Fi it's fine now.

Everybody, i had slow wifi for a few days on my iphone 6... I went to Apple Genius to rule out having a defective phone. They replaced and told me not to restore... I didnt and the problem continued on the new phone. Its not us, our phone nor router.. We have to complain to them instead of each other so the can make an update. I couldnt believe eveyone i talked to said i was the first person with this problem and i talked to many. I will try switching from Wep to WP on my router.

Outdaswats, it seems like there are a number of issues that are causing this problem. I doubt you had a bad wifi module - that's very unlikely. Your problem probably could have been fixed by re-setting your network settings, or some other relatively simple fix. You're lucky.


Others have tried everything and still cannot connect, which likely means it's just an old router (and beyond firmware updates).


Replacing the phone should be the absolute last resort, and that still may not fix the problem. I had to buy a new router, but now my wifi speeds are near-instantaneous.


Just to let others know, I believe the problem has to do with the type of router that one has - those that are dual-band, single channel may have problems. If you can set a WPA2 password for each channel then you have a dual-channel router (and your phone will likely connect just fine, provided you have a different WPA2 password for each channel).

I had a D-Link WBR-2310 (2.4 GHz only) setup with WEP. Mine and my wife's iPhone 6 had horrible download and upload speeds. I did a network settings reset on both of our phones along with changing from WEP to WPA2. That seemed to fix the issue, but only for about 12 hours. After ~12 hours, we were having the same issues again. Sometimes, after returning from work or going out and running errands, our iPhone's wouldn't connect back to our home wifi unless we rebooted our phones. I even tested just rebooting the router and not our iPhone's, but our iPhone's would still not connect. We would have to reboot our phones.


So, I decided to get the Belkin N600 DB (2.4 & 5.0 GHz) yesterday. I set up the router with WPA2 and got our iPhone's connected to it. Everything was going good for ~12 hours. Then, the same exact issues we were having with the D-Link WBR-2310 were happening with the new Belkin N600 DB.


Every time this happens, I go into the Wifi settings on our iPhones and there are ZERO SSID's available. I put the phones into airplane mode, then out of airplane mode and still there are ZERO SSID's available.


Only after you reboot the phones will SSID's appear in the Wifi settings again. Then, it will automatically connect to wifi because it finds our how wifi network and connects to it.


This is indeed an issue with iOS 8 and not the iPhone 6/6+ hardware because this same exact issue is happening with our iPad 3 with iOS 8 on it.

I have an iPhone 6+...I also have an iPad Air ... Wife has the 5s .... I have 2 Apple Airport Extreme Routers.... I'm running Fios 150/150mb


SLOW speeds on 6+... only getting 50mb ... yep, only 50mb


iPad Air ... 148mb

5s ... 110mb


Running 5ghz only on a WPA2 network.


Explain please. I've reset Network settings, restored phone to new, disabled LTE for calls, disabled (ring iPad nearby) etc.


Ready to return the 6+


Slow wifi, combined with ridiculous bluetooth issues in my ford car, also keyboard shortcuts locking up screen and crashing apps, constant rotation issues (sometimes volume popup is even upside down), location services always thinks I'm in Baltimore despite being on the West Coast, same voice memos constantly reload on iTunes syncing.


Tired of this ... last time I update OS early. I don't have time for this...... Soooooooooo Disappointed with these 3 iOS releases.


Genius Appt for Thursday.

Oct 7, 2014 7:05 AM in response to Dolphster

Dolphster I feel as frustrated as you do regarding the 6+ and am ready to return it if this Wifi issue isn't fixed soon. I don't have time to wait around for it because I need my 6+ internet connectivity for work.


I got the 6+ last night and after connecting it to my wifi I noticed immediately that pages and apps were running very, very slowly, if at all. I tried using the wifi with my 5 and it zipped along as usual. I reset the network settings and it worked great for about 15 minutes. I understand maybe I should try switching my router (Verizon FIOs) to WPA2 but I don't remember the login information. It seems to run fine on LTE at least, but I don't want all my data used up.


Sigh...Apple please get this fixed soon or I am getting a Samsung Galaxy phone. I know those work well with Wifi.
