I had a wifi problem on my RPi4 and my seller replaced the board. Can not say it solved the wifi issue but I got another one. Even Hassio (the same installation) is running on ethernet, in few hours the static IP address is swapped to another one!! And of course I cannot signon and all sonoff sensors loose connection with the Hassio. I just see on my router the new IP address allocated for this board, it is always the same: 192.168.0.37 . Maybe it happens because I am using the old static IP address from different MAC ? What helps is power reset only.
Can anyone explain this behavior? what can I do to resolve it?
I found the issue but still have a problem to resolve it.
for the new RPi board the system created a new net connection profile. in this profile there are records with this new IP address. And what’s interesting I cannot remove them. They all with capital letters despite normal records. if I attempt to remove them with nmcli it says: “Error: invalid setting argument”. the example of the proflie records below
