apple: iOS 16.4.1 (a) has not fixed the wifi drop problem I have downloaded the patch and it dropped the connection within 15 minutes. This issue is on an iPad Pro 12.9 inch 5th Generation. It is getting tedious having to reset /reboot 5-7 times a day if i walk away for 2 minutes it needs a reboot

I just updated to version 16.5.1 c on my iPhone 11. I join my network fine and wifi looks ok then within minutes it disconnects.

checked my internet router and signal all ok. My ipad which i havent updated is fine. Connects and stays connected.

its defo the update thats the problem.

I noticed 2 of my iPhone have this same issue. Although I can connect to the WiFi, the symbol that usually shows up on the side of the signal does not appear. also shows there is no internet connection even if already obtained the ip address and dns of the host which is the wifi router.

I don't see the relevance of asking for the battery life of their phones because most of the users have only started complaining about intermittent wifi and lost wifi passwords since the most recent update, or is this just coincidence. Has Apple altered a few global settings along the way?

We have four or five Apple devices including various generations of iPhones and iMacs that randomly forgot the wifi password and from different locations (as in home and work), so, as someone else has commented on here, rather than an iOS issue which obviously won't affect the older iPhones or the iMacs, has the keychain password protocols been altered/tweaked in some way which is causing the issues, just seems to be the common element which ties all these devices together?

I’ve started having this issue, where my iPhone 13 Pro Max running iOS 16.4.1 connects to wifi, successfully, but then seconds later disconnects. I have been running iOS 16.4.1 for a while so I’m not sure why the issue has just started happening. So far to troubleshoot, I’ve tried forgetting the network, power cycling the phone, & then today I reset my network settings. The issue still persists.

First time IPhone user here. When I got it I received a notification of update to 16.4.1. Thought its for good but got me frustrated. I am encountering this slow internet and logging apps. At first I thought it’s our service provider but when I checked my Android speed test it’s reached 300mbps while in IOS only at 6 mbps. I’ve done troubleshooting and YouTube tutorials to solve this issue. At most speed I get is around 15mbs.

Hoping to get this fixed soon.

For now, still heavily using android.

Same here. On a 14Pro running 16.4.1(a) and my wi-fi symbol has disappeared. Have reset network settings, rebooted router and phone, tried the airplane mode trick with no success. However, I disabled mobile data and am still able to navigate to some websites (like this one, and the Facebook app), but other apps (Speedtest, Marvel Snap) say I don’t have an internet connection. My wife’s iphone14 running 16.3 is absolutely fine.

My spouse and I both have the same problem. I have the 14 Plus she has the 14. After updating to 16.4.1 and subsequent 16.4.1(a) we constantly lose WiFi and when trying to join networks our phones just say "Unable to connect to network." I know the network is working because the rest of my network is up and running. This happens across multiple networks and no consistent timing. When we are connected to WiFi the speeds are much lower than normal and there will be times social media sites cannot even load videos.

I just discovered that my Wi-Fi isn’t working as well when I tried to connect my brand new Roborock S8 to home network and failed multiple times 🤦‍♀️. Apparently I’ve been on my mobile network all this time without noticing it since updating to 16.4.1(a) - the settings show that I’m connected to Wi-Fi but the Wi-Fi sign doesn’t show in the upper right corner and when I turn mobile network off there is no internet connection at all. Rebooting and resetting network settings didn’t help.

Apple needs to fix it asap!

Where is Apple Support!? Hello?

Existing issue through multiple OS version releases...

Apple: *sticks fingers in ears & closes eyes*

"Nope. We'll continue to ignore this and let the community address (as best they can) and hope they go away."

So, I manage a facility that has multiple iPads 50-60ish and the fact that this is a persisting issue through multiple updates and versions of the OS updates ...is unbelieveably frustrating. Then that frustration compounds by the fact that there are never any solutions to things like this. I have searched and searched and see variations to this issue going back to much, much older versions of iOS... tried all I've found in my searches and nothing resolves this issue and yet, Apple support is MIA. \endrant (for now)

My issues, just like yours @Fran-Siam and others. Here are my specifics:

Since the OS 16.4.1 through 17.0.3 updates we have seen this issue. Wifi disconnects, then reconnects. Sometimes it happens after a device goes idle, sometimes it happens while using. Sometimes in close proximity of an AP, others while walking enroute to another in our mesh network. I've attempted to adjust DNS settings, refreshing network settings, sticking tounge out and pressing buttons... still have issues on both iPads of various model version as well as iPhones where the wifi just drops then after sometimes having to go into wifi and actually click the SSID and *boom* reconnects. Other times, after some delays... say up to 1-2 minutes, the connection clears itself and re-establishes the connection. The devices are used for critical functions in some areas and has become more and more of an issue, yet cannot get any viable solution (the 1-2 min delays can be critical as a result).

My corporate is trying to force us to go to Android tablets because Apple refuses to add any SSO cross functionality and issues like this that persist are going to force our hands. Locally, we prefer the iOS devices but have no leg to stand on in fighting to keep and maintain them if we cannot either get support or solution to a persisitent issue.
