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 have this same issue since updating to 11.4 on my X. Every time the phone goes to the screen saver, it loses my home wifi network and keeps asking for the password, unless I go in through Preferences>Wifi to reacquire it. Irritating to say the least.


I cannot believe apple has become so inept with their software. Siri, can you fix this? Haha...that was a snide joke.

I experienced similar issues with two of my phones since iOS 11.3 (upgrade to 11.4 did not help). It was definitely not my router as my Kindle works fine. Had tried just about every logical thing to fix this, but the only workaround that is holding up is adding the MAC addresses of all my devices to the router and enabling MAC filtering on the router. My phones have not dropped the wifi signal since I did this a couple of days ago.

I’m wondering how aware they are. I’ve been reading the 11.4.1 developer blogs and can’t find anything about the WiFi issue, but lots on WiFi message syncing and other things that use WiFi. It could be that the WiFi issue that we‘re experiencing is just a symptom of a new feature that’s in 11.4, but some are reporting the problem with 11.3 also.

Had similar problem with my IOS devices losing then not reconnecting to home wifi. Only solution I have found is to turn router/modem off for 30+ seconds, then not long after it is restarted the IOS will reconnect to wifi. at first this was happening everyday, now just every several days. Hope Apple has some kind of fix in the works.

I’m now thinking of a new router. I notice that when I’m out of the house an on other unsecured networks, everything is fine. I’m now in DC on my daughter’s secured network, and again, just fine. Could my router be going bad and only affecting one device? My iPad? Not likely, but worth a shot buying a new one from Costco. If there’s no difference I can always return it,
