@Annieg 

Have you tried forgetting the connection on your phone and then rebooting your router before trying to connect again?

[Annieg]

Yes , done all that!!

There is anecdotal talk of a fix on the below Samsung forum:
https://us.community.samsung.com/t5/Galaxy-S20/Samsung-s20-ultra-dropping-WiFi-connection-constantly...
Apparently changing to a 5Ghz WiFi connection resolved on persons problems.
Someone else has reported fixing the issue by manually changing the MAC address of their phone (an alternative WiFi ID number).
Finally someone else set a static IP address and that seemed to fix their issue.
I would also check if there is an update due for the phone and the router in case the issue is at that end.
