updated to 18.3 on iphone 14 on 1/29/25. This morning Feb.1, getting intermittent wifi. Phone goes between wifi then 5g, then sometimes LTE, very quickly. My modem and router are fine - no problems, had provider check everything, so I know it's the update.

iPhone 14, iOS 18
IOS 18.3.1 is preventing my iphone from connecting to my hide’n WiFi network. All my other devices connect without a problem. It is 18.3.1 that has caused the failure. Apple, please fix this issue.
I tried the hard reset you mentioned here, and it did not work for me. I’m glad you got it to work. I hope it continues.
There must be something else going on with the 18.3 download, my iPad still works fine because I Did Not do the new update...
my iphone got cellular bricked. i am not getting signal at all. on latest fimware. it was working fine, i turned on and off the airplane mode and poof signal gone and idk what to do now
i have had the same issue. For me it seems related to when I use Google Chrome on the iPhone. Rebooting the device has fixed this until some point in the future (which as of today I am pointing to using Chrome for a bit)
Mine kind of self-corrected, but before it did - I tried a quick re-set of the phone that the Geek Squad showed me for anytime the phone goes wonky. Here it is: press the "up" side key and then the "down" and then hold the right side "power" button until screen goes black. Phone will reboot and then I manually shut down the phone and restart it. I don't know if this helped, but I've been fine now. You don't lose any settings or info by doing this, it just shakes things back to normal.
Same thing f here on 15 pro max. I know it’s not the wifi as everyone else’s phone is continuously connected while mine which is the only one on iOS 18.3 randomly drops wifi and reconnects after
Standard iphone 14, my phone does connect to wifi but since the update it's always so slow my Instagram feed barely loads, regardless of whatever wifi I'm using
Mine is iPhone 15 Pro. It is not connecting to home WiFi. It connects to my company WiFi. Is it something to do with MDM.
iPhone 14 won't connect to Wi-Fi after iOS 18.3 update
