In environments where there are multiple access points, the most recent update to the phone has killed the network access when it switches access point!! I have to keep turning off WiFi and turn it back on again.
I will be interested in following this comment as I have been having the same issue, having to turn the WiFi on and off two or three times a day plus restarting my S20 5g occasionally to get stable WiFi connection.
Thank you! I think I have identified the fault. Under WiFi > Tap the 3 dots > Intelligent WiFi > Disable WiFi Power Saving Mode. Since doing this, I have not had the issue, I have walked around the house, hopping between access points and it seems okay! Obviously this may now compromise my battery life somewhat, but could be the resolution. How do we make Samsung aware?
