Thank you for participating in this thread!
First of all - my internet connection is very solid, 50 mb cabel connection.
Secondly, I have now tried the reset functionality (this jumps the BS5/BM5 software back to 4.xx.xx.xxxx version) - and now .... when I try to manually update it - it does the same! - Stalls at 0 % downloaded ....arrrg!
I tried to use N.radio - no problem at all
I looked a the network info - the audio-product receives a network IP and everything is OK from that perspective...hmm!?
