This is a strange one.

I have a Boom and three SB3 units. My Boom seems to have lost all networking capabilities. I have used it on wifi for years, and whilst it still connects to wifi and obtains an IP address, and sees the local music server, I can't ping the device nor can it play any music.

So I've swapped over to cable and it's doing exactly the same.

Can anyone suggest what might be wrong with it?

Many thanks.
