Question: 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.

There’s more to the conversation

Hi

Turn off your router for 20 /30 seconds when it's back on go to settings on ipad

Down to reset Reset network settings After reset enter your router wireless key.

Later go to website for your make of router check for firmware update.

Cheers

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.

I have the same problem with iPhone 6s and iPad Air 2, both of them don't connect to my WiFi after disconnecting them once, the only way to do this is restarting device. I've tried everything including router restarting.

This is a bug since the iOS 11.3 update. It happens at home, work and everywhere else.


To me seems like wifi shuts off to save power and loses Routers IP.


PLEASE APPLE ADDRESS THIS!

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!
