iOS 11.4 WiFi Problems

iOS 11.4 on iPhone 6 and iPad Pro. WiFi drops on iPad and then does not reconnect until numerous attempts, turning WiFi on/off, connecting to different network, or powering iPad on/off. Phone has no problem nor do my many Windows computers nor do my SmartTVs. It’s not my router or signal strength. Is this an iPad Pro chipset problem? Also, I have WiFi Networking turned off under Privacy setting for both phone and iPad

Same issue here - I have the following four iOS devices in use, all running on 11.4:


iPad Air 2 128GB: Badly affected by WiFi drops and reconnect problems

iPhone 6 16GB: Occasionally affected by WiFi drops and reconnect problems

iPhone 7 128GB: Not affected

iPad Pro 256GB: Not affected


The WiFi reconnect problems occured after upgrading to iOS 11.4!


The interesting thing is, that on the first two devices, the connection drops after about 10 seconds despite having connected succesfully. This can also be seen in the log of the router. The devices usually reconnect after roughly a minute and then stay connected until you go into screen saver mode or turn off the device.


Another problem that appears on all 4 devices since upgrading to 11.x, is the fact that the devices drop their WiFi connections a few seconds after the screen lock becomes active. This means that unless you have a mobile data connection, push mails and instant messages are being received with a huge delay. I have an old iPhone 5S that still runs on iOS 10.3 and that device is not affected by any of the above mentioned WiFi issues.

I’ve suffered this problem for well over a year and with my iPhone 7, not my iPad. As you point out, other devices work fine (iPad, MacBook Pro), so its not the router. Besides which, it happens everywhere. I can’t go asking hotels, restaurants, cafes etc: “please reset your router”. I took my phone into an AppleStore; they tested and said “no hardware fault. Try backup, factory reset, restore”. I did that and it ‘seemed’ to help for a brief while.


The device simply drops WiFi when it feels like. Sometimes when the device sleeps and is subsequently woken. Sometimes whilst I’m physically using it. Most frustrating. Check out the screenshots. Often WiFi disconnects & is either off or even grayed out, so I can’t re-enable, other times the WiFi settings show me as connected, but the status bar shows me as on 3G/4G or whatever. Switching WiFi sources, toggling various settings or even rebooting the device are usually needed to get WiFi functioning again.


Gone are the days of: “...and it just works”. I would suspect faulty hardware. But if their tests aren’t smart enough to detect it... or, worse still, your device behaves when they do... *** you gonna do?User uploaded fileUser uploaded fileUser uploaded file

Have the same issue... both with 802.1x, wpa2 and with no wireless security. Running 11.4 on ipad air 2. Seems that i have more success connecting when the access points, only uses the 20 mhz band, no auto, regardless of security config. Both my AP are HPE 560. Non of my other devices have issues counting 2 smart tv's, 3 Android phones, home automation from Danfoss and other random stuff. Ipad is USELESS without wifi.

A couple weeks ago I upgraded from my 4-year-old iPhone 5C (which worked fine but was too old to get updates anymore) to an iPhone 7. Yesterday I realized my new phone was randomly disconnecting from my home wifi and work wifi (auto-join is on for both and connection/router isn't an issue). When I try to manually reconnect, I get an error message saying the password is incorrect, even when I enter it correctly. While I can fix the issue by restarting my phone or going to General-Reset-Reset Network Settings, I don't want to do this all the time, especially since I have a small data plan. This is making me miss my trusty old 5C!

Great, and Apple just stopped signing 11.3.1 code, so there is NOOOO!!!! downgrading. Yes, thanks alot you F***, that a very expensive paperweight sitting on my desk!!! Are we really suppose to wait until IOS 12 is released, with no certainty that the issue is fixed. Just sign 11.3.1 or 11.3 again, or that poor soul at the Apple store is in for a treat 🙂

Yep.... big problem and now can’t roll back to 11.3.1 as it’s gone. I was at Apple yesterday and people were lined up with the same problem. Doesn’t seem to affect iPhones as much. Apple’s solution? The usual... But nothing works. It was very satisfying for me to see the “genius” wife out my iPad to ‘new’ state, reapply IOS, only to have my iPad refuse to connect to the store‘s WiFi.

Cmon apple...

get with it. Fix these crazy problems. Btw, a few acquai are running IOS12 BETA AND ARE HAVING THE SAME PROBLEM☹!

I hope people are reporting this, not just omplaining to each other. This problem is MAJOR. Geniuses at the Genius Bar can’t handle it. After having them set my iPad back to completely new, with 11.4, it wouldn’t sign on to their system either.



there have been SO MANY things wrong with their OS lately.... and from what so can find out, IOS 12b is also completely screwed up.
