HifiBerryOS "hijacked" the network?

Somehow yesterday some devices on my network were pointing to the HifiBerry as their network gateway and DHCP server.

How can this even happen?

Does the OS's boot sequence have it automatically turn on a "server mode" for a brief instant?


I've not been able to reproduce this reliably, so take it with a grain of salt. But this is what I suspected happened. I unplugged the power of a bunch of devices - TV, Chromecast, PS4, switch etc.. After everything came back online, the TV's built-in apps where not working. Everything else - Chromecast, PS4, etc. - was working fine.

Another weird tidbit: I could only see & access the HifiBerry's interface when I was in the same room and some access point as the HifiBerry.

The fix was to:

  1. unplug the HifiBerry
  2. restart the affected devices
  3. plug-in the HifiBerry


An extra weird tidbit that happened another day: the switch where those devices are connected - a Ubiquiti Unifi 8-port PoE switch - has logged some errors in the past about activating stuff to protect from loops in the network (spanning tree protocol maybe?).
