Re: SSH using hostname unreliable

I haven't had your specific problem, but I've had others relating to using the hostname.
These turned out to be Windows playing funny buggers with mDNS.
My present version of Win 10 works OK, but earlier versions did not.

Re: How can I make PI use wifi connection if ethernet cable is not working

Running Buster on an RPi 4, this happens automatically: If ethernet is connected, that is what is used by default for web traffic for example. If there is no ethernet, wifi is used. But, if ethernet is connected, I can SSH in using either wifi or ethernet (depending on which IP address I use). So, I...

Have you tried the new image burning utility:

It works perfectly burning Buster directly to an SD card.
There's an option to burn Kodi - though I haven't tried it.

Well, I always do headless installations.
The only thing I do is add a file called ssh to the SD card.
And with ethernet connected, it always just works!
Once I'm in using puTTY, then I can run raspi-config and enable VNC, etc.
Then in RealVNC, I configure the wireless.

Re: LAN connection does not work on RPi 4

It's easy to get yourself in a muddle when you do things this way.
IMHO, from years of bitter experience, it's better to set static IPs in the router and not fool around with the settings on the RPi.
