Removing Wifi card to replace with Coral - HA won't start

1

Hi All,
I have a project in which I want to use Frigate to recognize objects. I’m running HA from a mini PC running HAOS (no Proxmox or anything). To boost processing power, I bought a Coral TPU.
I’ve always run HA on a wired network connection so the wifi card in the mini PC is redundant. I took it out of the system in preparation for installing the coral, but then realized I need an adapter to install the coral TPU. When I tried to restart HA without the wifi card, it wouldn’t start. But after reinstalling the wifi card (mini PCI), everything was fine. So I’m guessing that it is stuck trying to find the missing network adapter. I tried SSHing into the system to run nmcli to disconnect the adapter, but I couldn’t find nmcli. So now I’m stuck.

Any ideas?

Hi dpeeling,

I suggest with the wifi card back in, you go in the bios, there should be a way to disable it.

Just to close the loop on this:
It wasn’t in Bios since it was a removable wifi PCIe card.
Not sure if it was necessary, but I figured out how to deactivate a network connection via the HA cli. I believe it was:
ha network interface interfacename -e

Then once I swapped in the Coral TPU, it was working and the system booted fine. Now happily running frigate

That’s good to know. I thinking about buying a mini pc with the intention of swopping out the wifi module for a coral module.

@dpeeling I am really struggling to get my HA instance (on an N150) to boot properly after removing the wifi board. The system does boot, but there’s no ip address assigned to the eth port, so I can’t connect to it. I don’t understand why removing the wifi adapter would prevent the eth from grabbing an ip address.
