Brennan B3 connectivity

Hi. I have a Brennan b3. It talks with MB & receives album name & tracks once the cd had been ripped.
This worked perfectly with my Sky router. However, I upgraded my Sky Router & now my Brennan can’t find MB.
Calls to Sky have been unsuccessful, they blame the Brennan but it’s really strange how my old router was fine. Any suggestions welcome. Thankyou.

My guess is that you may have been assigned a new IP address with the new router, and it is being blocked (perhaps previously used by a QNap device). In that case, you can contact @Zas with your new IP address and he can look into it.
