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?

Context

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?).

  HiFiBerryOS will enable an access point on WLAN if no network connection is availble. Is your Pi connected to Ethernet or WiFi?

  It is connected via wifi. So, while the system was rebooting, the other devices searched for a router and the Pi offered itself?

  Same issue here - you really should be disabling this "access point" option, or at the very least DHCP once the device is connected to a network. Or better yet - perhaps just let us disable the whole feature all together.

   

  Also pretty disapointed in the HiFi Berry team for not responding to this post since May! As it stands I can't have this device on my network, as it starts it's own DHCP server and shafts other devices asking for DHCP. No way to disable this. Having to fall back to manually installing a bunch of crap on a raspian image... I bought the DAC because of the ease of getting something up and running with HifiberryOS but now I have to find different software, kind of regretting my purchase.

  @Matt:
  
  HiFiBerryOS is a free software. There is a lot of work on this, but we simply can't implement all things that some user wants. You might see that there is a bug report here:

  For some reason this is still an issue! 🤦 Creating a noap file on the boot partition stops it from happening but feels like we should be past the random restart of this service by now!
