Wi-Fi disconnecting randomly after iOS 18.3.1 update on iPhone 14

Anyone else got the 18.3.1 update recently? I did and it wouldn't stop disconnecting my wifi on both iPhone 14 and ipad air 4. My partner has an android sitting right beside me and he has no issues so it's not our Wifi or router. This also happens to me in school when my schoolmates face no issues with their connection. Super annoying especially when I am gaming and gets disconnected.

New Passkey:

Ask the superintendent for a new passkey to get into the WiFi.


Troubleshooting iPhone WiFi:

See if anything here helps...


A few thoughts to try...

I. Clear the Temporary Internet Files:


II. Restart your Router:

  1. Power: off the router
  2. Wait: 30 seconds
  3. Power: It back on


III. Boot in Safe Mode:

In Safe ModeLogin Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install. For instructions, go here: How to Use safe Mode on your Mac - Apple Support


IV. Try a New Admin User:

What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.


V. Reset your SMC and your NVRAM:

(Applies to Intel-Basel Macs Only) Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. Networking) become corrupted, technically. So, reset both on your Mac. So, reset the SMC and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.

Start With This:


VI. Add Back the Network:

  1. Go to: Settings
  2. Tap: Wi-Fi
  3. Remove: the network
  4. Wait: 30 seconds
  5. Add: the network back
