You could try forgetting the Wi-Fi connection in your devices settings and then go ahead and reset up the Wi-Fi connection to see if that helps @Shane666
As a process of elimination try connecting to another Wi-Fi connection such as a friwnds Home Broadband Router or coffee shop etc and see how stable the connection is.
My Wi-Fi connection has remained stable since the very latest software update so I'm not entirely convinced it's the update causing the conflict.

The advice I offer is my own and does not represent Samsung’s position.

I agree. Since the update and when my S21 phone has Wi-Fi turned on my home Wi-Fi download speed drops to 0.1 Mbps and all other devices in the house are unable to use home Wi-Fi. When I turn Wi-Fi off on my phone the home Wi-Fi speeds go back to normal. I have also noticed battery does not last as long as normal.
I have had 2 engineers checking my line and router which test OK . I have reset my phone, cleared cache on apps I have used, but the problem still persists.
Since I have no mobile signal at home I depend on wi-fi calling so my phone is rendered useless.
Me too! I'm having problem these 2 days after updating to the ONE UI software. I'm figuring out whats causing the problem... I've tried all ways from forgetting network.. restarting the phone... power off and on my wifi... my connection still drops and then stuck at that fan with an "!" mark.
I just found out that there is this function called the Intelligent Wifi.
Go to Settings. Connections. Click onto your WiFi. Top right corner 3dots. Click Intelligent Wi-Fi. I OFF both "Switch to better WiFi network" , "Turn Wi-Fi on/off automatically".
I'm not having any problem for about 10mins already.. let me try playing a game to see if the WiFi network will drop again... try it! And let me know if it works for u!
