A boring problem

[lyapounov]

Hi friends

since a few weeks, the same problem happens.

I switch on my Klimax.

And then it takes between 10 to 15 minutes before

- the klimax is recognized
- it plays music

What can be the issue? How come it used to be switched on instantaneously, and now I need to wait 10-15 minutes before being able to play my music.

For info:

1) the klimax has its IP adrdess, so not a network issue
2) I have a yamaha network player which is playing without issue, so not an issue with my router

How can I debug this ?

(One more reason to say than UPnP is a rubish protocol)
