Q: iOS 8 Wi-Fi problems

WI-Fi problems on iPad Air, iPad mini with Retina display and iPhone 5S after upgrading to iOS 8.

Typical results from OOKLA Speedtest before upgrade: Ping 17 ms, Upload 21 Mbps, Download 4.4 Mbps

Typical results after upgrade: Ping 39 ms, Download 2.9 Mbps, Upload 0.47 Mbps

iPad 2 with iOS 7.1.2 get 15 Mbps download and 4.4 upload on the same network.

Resetting network settings on the iOS 8 devices did not improve the performance.

Changing band on the router from 2.4 GHz to 5 GHz did give me back the speed on all devices.

However the speed occasonally drops on the iOS 8 devices, and the signal strengt can go from full til lost connection without moving the devices.

Also sometimes the Wi-Fi SweetSpots app report 0 mbps when the signal strenght is indicated as full and then suddenly go up to around 58 Mbps again.

It is almost like the device is trying to use cellular network that I do not have on the iPads before it suddenly switches back to Wi-fi nettwork again.

I am thinking about going back to my iPad 2 with iOS 7.1.2 that is working perfectly until the Wi-Fi issues are resolved.

 

Any help will be very much appreciated!

    "very annoying" is becoming a bit of an understatement

     

    My iPhone just dropped Wi-Fi, I'm in the same room as the router & all stable. Dug out my wife's old iPod (running IOS6) & full Wi-Fi

     

    Tried restarting phone, can see router but when I try to connect get asked for password. Enter password, incorrect.

     

    Another restart, tried turning Wi-Fi off then on again, yet another restart. Still would not connevt. Tried "forget this network" option, then another restart & it finally connected

     

    Now I know I am ignorant in these matters, but that does not sound like a hardware fault with my router

    On iOS 8.3 fortunately, There wasn't any problem with the wifi for me. But now, on iOS 8.4, the wifried problem is bothering me very often. It's really frustrating when you are watching any kind of a video or playing a song on the internet, and suddenly NO WIFI just like that out of nowhere.. iOS 8.4.1 is on it's way, so I really hope this problem gets finally fixed!

    To those having Wi-Fi issues:  iOS 9 hopefully will resolve the iOS Wi-Fi issues as well. Hang in there folks...

    So that would explain why devices still running IOS7 seem to be immune from the problems

    Do you know if IOS9 will be available for all devices running IOS9? Hate to think some won't be able to upgrade

     

    Regarding your first sentence, yes it would explain it as mDNSResponder was used in iOS 7. Regarding your second sentence, you probably meant to say "Do you know if iOS9 will be available for all devices running iOS8? (instead of iOS9). The answer is iPhone 4s and above. For iPads see the link below:

    Yes, all the pieces are falling into place now, Apple have finally manned up and ditched the ill stared discoveryd for the tried and tested mDNSresponder (this is all over the internet as it affects Yosemite).

     

    The root cause of 12 month's of intermittent wifi issues.

     

    No apology, no nothing.

     

    This will leave a bitter taste in many people's mouths.

    The upgrade to iOS 8.4 has slowed the internet so much that it renders wi-fi useless on my iPhone 6

    Try turning Bluetooth off and see if it helps. If it does please report here.

    In addition to PS61's suggestion (which works for me) you might try switching to the 5GHz band if your router has one. Various reports state that there is a conflict with the networking routine currently used in iOS 8 and Bluetooth and switching from the 2.4 to the 5 band has helps some. The drawback is that the 5GHz band has a far shorter range so if your house is large you will get better access with 2.4. According to Apple, iOS 9 should be available in the fall and hopefully will improve networking.

    That's not likely.  IF there was an IOS-related networking problem and IF Apple had a solution, they wouldn't wait - 8.4.1 would be provided with the solution.

    The main problem with the 2.4Ghz band is that it is very crowded. WiFi is not the only use of the band. Portable (not cellular) phones, microwave ovens, alarms, doorbells and so on crowd the band, many poorly regulated and/or engineered. The 5Ghz band is less crowded (although you'll still find home phones and alarms in there) but is slowly getting more use. So the band with the best range is also the most crowded. Something usually gives.

    Oh, it is. Just wait and see....
