iPad Air 2 WiFi Connectivity Issues: RESOLVED

In a previous post, I told the tale of how my brand new iPad Air 2 would not stay connected to WiFi (typically losing connection after a certain amount of idle time.) I would have to turn off WiFi and back on again to make a connection. In the same house, I had 2 iPhone 5's (not 5s), an iPad 3rd-gen and iPad 4th Gen all running iOS 8.1 with no connectivity issues. Only the iPad Air 2 would drop its connection.


I tried the following:

  • Restarting WiFi router
  • Turning off WiFi Networking support on the iPad
  • Resetting network settings on the iPad
  • Restoring the iPad (using backup)
  • Restoring the iPad to factory settings (using backup and setting up as new iPad)


Nothing seemed to help. I went to an Apple store and a Genius replaced the unit for me. When I got home, I connected to my WiFi and set it up as a new iPad without restoring from backup and then I let it sit for an hour to see if it maintained a connection. IT LOST CONNECTION AGAIN.


Then I went into my router settings (Linksys Smart WiFi) and made the following changes under "Wireless Settings":

  • Changed the 2.4 GHz Network Mode from "Mixed" to "802.11b/g Only"
  • Changed the 5 GHz Network Mode from "Mixed" to "802.11a Only"


That seemed to do the trick. If it hadn't, my next step was to try to set an IP reservation (under DHCP) for the iPad which, after thinking about it, I had to do for my 2 Nest Thermostats a couple of years ago after they kept dropping their connections.


I hope others who are having this issue with their iPad Air 2's have similar success with this resolution.

I wanted to find out about this. Was this particular procedure done with your iTunes program, and not by erasing everything from the iOS device itself?


I might add one thing here, for others reading here. If someone does the factory default reset, by using iTunes ... it would be a good "troubleshooting methodology" to not restore your backup at first. You would want to see how your iPad works without any of your stuff on there or any of your apps on there and just run it and test it out, as a clean and fresh system ... all by itself. This will tell you a lot, by itself.

I've run across a few users here on this forum who said their problem was related to certain apps. And then others could be problems with some settings or files. I would advise others to not restore, and simply check out the clean operation without any files or settings you had before. Now, if I ran into problems from that kind of "setup" ... and it was a clean install ... that's when I would be running down to the Apple Store and tell them that my iPad was not working, as it should (show them exactly what it is) from being "factory fresh". At that point, they couldn't point to any of your files or apps ... you see ... :-) ...


Now, for other readers who want to know how to reset to factory default condition - by using your iTunes program, see the last link below. I'm including a bunch of links on backups, because anyone who is trying that should do their backups, even if they do not restore, right off the bat ... and as I said ... one should not restore their backup, right off the bat, but check out the operation first.

This is not resolved, changing your router to 802.11b/g or a is not a resolution of the problem.

The iPad Air 2 is suppose to run under 802.11ac isn't it? This setting your router to b/g or /a is a step backwards in technology.

Come on.

Hi Tom.


While I agree that I should not have had to go in and fiddle with my router settings, my iPad now stays connected without having to stop/start my iPad's WiFi. It's a proactive step I can take to ensure my iPad works continuously until Apple wakes up and fixes the problem.


And I could have done without the abrasive tone at the end.


(BTW, my router is not equipped with 802.11ac.)

Agree. I would put the suggested changes in the 'temporary workaround' category, and don't consider it a long term solution. I'm trying them out myself just to see if it actually does work as workaround until Apple (or Linksys) figures this out.


This approach even contradicts Apple's recommended wifi settings... http://http://support.apple.com/kb/ht4199?viewlocale=en_US


On the subject of using a fresh iPad to test this out, yesterday I did a factory restore on the iPad itself (erasing all content & settings from the iPad) then set it up as a new iPad. I never plugged it into iTunes. I connected the blank iPad to my network and then did some web surfing in Safari. After letting the iPad sleep for a bit, I was easily able to reproduce the stalled/lost connection issue.

So, for most households this is a theoretical issue versus a real issue as A/B/N speeds all exceed the typical broadband speed coming into your network. In my case, I net only about 15 Mbps download speed from AT&T and was able to achieve this both before and after making the changes described in this thread.


That said, what will be impacted is speed within your network. So streaming from your own internal servers will suffer under A speeds compared to N speeds.

Interesting workaround - it appears Linksys has some problems with their routers operating in mixed mode. I had N-only on my 5GHz band on the EA4500, but that didn't work.


as41 - its unlikely you will get 50mpbs from a-only setting. Both a and g wireless networks are early-2000s standards that only allow a max theoretical bandwidth of 54mbps, however signal attenuation and interference will degrade that significantly. At reasonable distances and with normal levels of interference, you would probably get something closer to 10mpbs. I had this exact argument with a verizon rep when I first had FiOS installed - I bought the 35/35 Mbps plan, but the router the tech installed was a wireless-g router. He kept trying to tell me that it was OK since the router had a 54mbps speed...

You shouldn't need to make those router changes, it sounds like there's something else wrong with your router or its settings. Have you checked to see if Linksys have any firmware updates for it? Here's a document on Apple's recommended settings for WiFi routers:
