Since updating latest IOS 15.4.1 my Wifi is not working

I've updated my Iphone 13 (MLQA3B/A) to 15.4.1 today - and since I did the WIFI connection for new and existing WIFI connections is failing.

It attempts to connect and fails...

I've attempted a WIFI network setting reset, restarted the device etc...

What can I do - is there a way I can downgrade the phone to an IOS before 15.4.1?


Frustrating!

iPhone 13

Check your WiFi Router / Modem for --> Recommended settings for Wi-Fi routers and access points ...


Connecting to Wifi is the first part and then getting connected to the Internet is the second

  1. If you connect to Wifi, doesn't necessarily mean you are connected to the internet. If you are not connected to wifi could be a problem with iPhone settings or Router/Modem Settings
  2. If you are not connected to the internet is the sole issue of Router / Modem Settings. Contact your ISP immediately


For your Internet connection.

  • Over Cellular: contact your Carrier (Cellular Service Provider). The agency who issued the SIM to you
  • Over WiFI: Contact your ISP (Internet Service Provider), the agency who provided the Internet Service on your Modem/Router to you


However --> Connect iPhone to the Internet - Apple Support


Since updating latest IOS 15.4.1 my Wifi is not working
