Can you please elaborate a little more?
I also have problems with my newly bought (used) KEF LS50W keeping/reestablishing the Wifi Connection.
I have to connect the KEF LS50W manually from the 2.4 ghz net to the 5 ghz net where it works for hours without any hickups (2.4 ghz stutters constantly). As soon as I turn off the KEFs they don’t reconnect to the Wifi at all (red wifi sign) upon restart.
Do I really have to have the KEFs switched on all the time?
I appreciate any help here
