After update of #FreeBSD-CURRENT c 2023-04-03, "#libvmmapi.so" was changed to "*.so.6", which made -- "grub2-bhyve" to not start, which in turn made -- #wifibox not to provide a connection of course (see the log in "/var/run/wifibox" somewhere).

Switched to FreeBSD-port of #iwlwifi driver (connection was 802.11g, not .11n); updated "ports" trees; recompiled "grub2-bhyve" & "net/wifibox{,-alpine,-core}" ports.

"kldunload if_iwlwifi" caused a panic; sure🤷🏽‍♂️

Then "wifibox" was working again.
