Greetings.
I am trying to make a guest VM work with wifi connection.
Nothing too fancy: alpine vm in bhyve, and use wifi to connect to the outside world.
It worked just fine with
I tried to create a "switch" in vm-bhyve with
Then I try to
I believe that would be an extremely simple thing to do and for sure many people did it successfully. I couldn't find the exact threads though. Most of them deal with much more sophisticated configurations than the one that I am looking to use.
Maybe the culprit is the quirks of the wifi driver, or some bugged defaults in vm-bhyve.
I wish I could take away from it some acquired knowledge to be able to debug such things in future.
Thanks in advance.
Here's some useful outputs:

eth0 connection (meaning connecting to the world using an ethernet cable) but when switching to wlan0 something breaks though. I tried to create a "switch" in vm-bhyve with
wlan0 as the physical device, and also tried to create a custom manually configured bridge (though it seems I did pretty much the same thing as the vm-bhyve switch does: ifconfig bridge0 addm wlan0 addm tap0). Then I try to
udhcpc in alpine to recieve IP. On the host side I see dhcp requests coming from alpine and getting no response.
