I bought a replacement phone for my Samsung Galaxy S8, the new Galaxy A53 5G. Already out of the box performing the installation I couldn't get a connection to my Wifi Mesh network (Deco X60). Once in a while it did actually connect but not for long and when disconnected it often coulnd't reconnect again. After being very patient I finally made it through the whole setup process, but the connections still dropped.

On my S8 (still works fine apart from battery life) I have no problems at all. Also my wife's phone (S9) and my 4 daughters (S8 and 3 diffferent Iphones) experience no problems with the wifi whatsoever. All the other objects (Smart-tv, e-reader, Chromecasts, etc) work fine as do my work-laptop and my wife's. We've got the Deco X60 Mesh network running since august 2021.

Of course I tried to find out what it could be, so I ran a lot of tests, trying ever 'switch' in the settings. Because I thought my new phone was the problem I even reset it to factory default and reran the whole setup again, but still the same problem. Eventually I set up a second wifi-network with my old router and to my surprise I had no problems connecting to that wifi at all. The new A53 isn't the problem, its wifi works fine and fast (run several tests) but the connection to my Deco X60 is the problem.

I've posted this same problem on the Samsung Members forum, and a guy told me to post my problem here for he has had the exact same problem and an alternative Firmware version was the solution for him. So hopefully it will work for me to. Where can I get such alternative firmware?
