I have had an s23 ultra for 3 days, and lost wifi6 connection each day I see phone using 4g mobile when ols 20 ultra is still connected and working over wifi6.
I see there was a problem before with the s23 ultra and wifi6 but has that not been fixed?
After playing with the intelligent wifi it appears to be an interaction between Switch to mobile data if unstable wifi, and Switch to stronger wifi if avalable. If either is off then I stay connected to wifi and have no problem
Looks like when my phone switches to a stronger mesh unit as I move around the setting switch to mobile network on unstable wifi kicks in and I am stuck on mobile data then. Switching that option off fixes it. So looks like it detects you moving from one wifi to stronger as an unstable wifi.
