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!

That is until we hear about the disaster that it is, as we do with every other iOS and OS X update or upgrade from a few users


Really optimistc fellow, are you! No doubt we will hear from the disgruntled few who's Wi-Fi was working with 8 but now claim that their 9 ruined their connection. Probably one hour after release when that thread is started. As I mentioned before, there has always been reports of "issues" with Wi-Fi, on every iOS, every Android, every OS X, and as I am clairvoyant with iOS9 as well.

Disgruntled few? Interesting! How would you respond to the poster that stated:


"In my own case I spent hours with AppleCare Level 2 who remoted in through my PC into my iOS devices. They verified that my Wi-Fi (3 different Cisco APs) and my 4 iOS devices were set properly. As advised, I reset my devices to factory and followed other recommendations but to no avail. AppleCare then authorized a replacement of one of my iPhones. The replacement came with iOS7 and worked perfectly at the Apple Store and at home just like my MBP, my two Dells and my Toshiba PC (all flawless with the same ISP/router configuration). I then updated the new phone to iOS8 and prior to restoring my apps the new phone developed the same issue as before -- further calls to AppleCare and the case/issue is now in the hands of Engineering/Development. An Engineering tech then contacted me like many others on this thread and collected logs and data for analysis. So yes there is an issue and yes Apple is aware of it. And no it is not the router."

I have also had problems with wifi dropout after upgrading to IOS 8.4.1. and tried everything to no avail. I use a BT Home hub 5 and found by chance that turning off the BT wifi hot spot solved the problem for my iPad and iPhone. Both now rock steady. This can be done via the "find out more about BT wifi" to the bottom of the home page for the router manager. It would seem there is some conflict with the hot spot setup.

Something else you might like to try, there is another app that checks speed (free in App Store) - CloudCheck

In addition to speed you can move around & it shows wi-fi signal so you can identify and dead spots. There was a post about this some weeks (maybe months) ago in this thread



Good suggestion, old_chap. When time permits I will check it out myself. Thanks for the tip.... ✅





If the check shows any dead spots, something I came across might be useful:-


Improve your home wi-fi signal with an extra router


Want to boost your home wi-fi signal? One of the best techniques for receiving a more reliable internet connection is turning an old router into a repeater. This should extend your wireless signal to the darkest corners of your home, but you’ll likely spend 30 minutes setting it up.


Check your router’s manual

Some routers have repeater functionality built in, while others need customer firmware. Find out from your router’s manual to see if it’s possible to use a second wireless router to repeat the wi-fi signal or use it as a bridge – official documentation is available for the following Apple, Belkin and Linksys.


Enable the built-in repeater mode

Before starting, make a note of the MAC address of both the current (‘primary’) and ‘old’ routers. It’s often labelled on the bottom of the router and looks something like ’00:00:00:00:00:00′.

Configure your current (primary) router

  1. Power on your current ‘primary’ router and connect your computer to it via an Ethernet cable. Open a web browser on your computer and enter the Admin page URL (most are similar to http://192.168.1.1), then the username and password. The manual will contain this information and guidance to the admin page settings.
  2. Locate the wireless repeater settings on its Admin page and enable/change as appropriate – you’ll either have a drop-down menu to select your router’s mode or a checkbox to tick. This is often found in the ‘advanced’ wireless settings and named differently between brands, such as ‘Wireless Repeater’, ‘signal repeating’, ‘Wireless Bridging and Repeating > Repeater with Wireless Client Association’, or as with Apple ‘Wireless Bridge Mode’.
  3. In the wireless repeater settings, leave it set to access point mode. Fill in MAC address of the ‘old’ router and click Apply, Save, or as appropriate to save the new settings.
  4. Look for a setting relating to the router being set as the ‘DHCP Server’ and make sure it is enabled. It might not be present, but check in any sections that mention ‘LAN IP’ or ‘DHCP’. The IP address should be set to 192.168.0.1, then ‘starting’ IP address at 192.168.0.4, and ‘ending’ IP address 192.168.0.255. Save the settings.

Configure your old router

  1. Connect the Ethernet cable to your ‘old’ router and power it on. Enter the Admin page and locate the wireless repeater settings (similar to steps 1 and 2 above).
  2. In the wireless repeater settings, change it from ‘Access Point (AP)’ to the ‘repeater’ option (for some routers you may have to create a wireless bridge).
    Note: If you don’t find these settings, then this isn’t possible or you’ll need custom firmware.
  3. Enter the MAC address of your main (‘primary’) router, but other settings are different here.
  4. Look for LAN/IP address settings. Turn off any setting relating to using it as a ‘DHCP Server’ – you don’t want it to act as the chief router.
  5. Next, change its IP address to 192.168.0.2 and write this down as this will be the address used to enter its admin screen in the future. Save the settings.
  6. Make sure that the wireless settings are the same as those used by the main router (such as SSID (network name), security mode, Channel, and MAC Authentication).
  7. Next, make sure all routers are powered off. Wait a minute, then power on the ‘primary’ router.
  8. Pick a spot to locate your ‘old’ router (the ‘repeater’) in an area close to where you’ve struggled to get signal (this could be a different floor). Then, power it on and check if you now have an improved wireless signal.

Installing custom firmware

Some routers don’t have repeater mode built-in, while others have the capacity but require you to install custom firmware to unlock this functionality. There is a risk that you could brick your router and, although most can be revived by sticking a pen into its reset button, it could invalidate the router’s warranty.

Because of this and a more convoluted process, only advanced users should consider this. The DD-WRT website provides custom firmware and specific instructions for some routers.

If all else fails, you may need to buy a wireless booster or new router. Wireless networks aren’t always ideal – one solution to signal problems is to buy HomePlugs which use your home’s electrical mains circuit to share an internet connection.

Please remember that extending a wireless network at a point where it is near the extent of its range (i.e. slow and unreliable) will simply extend a slow and unreliable connection. It won't improve via wireless extension, it will just be bad for a longer distance. Extend it with a wired repeater and then you'll get a result.

Sep 14, 2015 7:26 AM in response to old_chap

Thank you, old_chap, good suggestions... I don't use extenders myself; in my bedroom wing, far from my main router, I use a second access point hard wired by Ethernet to my main modem/router. I thus get an excellent second radio with full ISP speeds. The transition between the main and secondary AP is totally seemless. Works very well for me.....

FWIW I had problems ever since iOS8, on multiple iPhones and iPads, but only with my Netgear R7000. A recent firmware upgrade to the router appears to have resolved the situation. It's not black or white - the standard isn't simple - Apple changed something with 8, but apparently Netgear were able to make their device compatible again. A great relief that it's finally fixed though!

Have been experiencing wifi issues with IOS8 and now IOS9.


Devices which at one point have experienced issues: IPad 2/IPad Air 2/IPhone 4S/IPad Mini.


Device which currently experiences wifi issue: IPhone 4S


Previous device issues resolved: IPad2 sold - someone elses problem. IPad Air2 warranty - replacement IPad Air 2 works fine on all networks. IPad Mini - Mysteriously began working - Still on IOS 8.4.


Updated IPhone 4S tonight hoping that the wifi issue would be fixed. Have been unable to connect to any wifi network for the last few months. I've reset network settings, wiped the phone, restarted the router and called Trump. Even he was st(r)umped.


After updating to IOS9 the, "incorrect password", message displayed even though I entered the correct password. I tried twice more and for some reason the third time it connected. But the wifi ran so slow that it disconnected/dropped/would not load a website. So I repeated the steps mentioned above. And yet again the wifi connected on third attempt and ran slowly then dropped. I spent two hours again trying to fix a simple issue that Apple should have fixed ages ago.


It's been a tough year dealing with all these wifi issues. I'm disappointed with the inability of apple to fix a critical issue. Apple, we are paying for your devices, among other reasons, to connect. Whether it be to the internet/work/family those connections are made primarily through wifi. This should have been fixed on day one. It's now been a year and I honestly love my apple products. But if your devices are unable to connect to wifi to do the most basic of things. You're going to lose customers.
