The installer detects the wifi hardware but will not display any networks that I know are within range. After install and going through the wifi instructions in the handbook (32.3.2) I still get no connection. sysctl net.wlan.devices returns "net.wlan.devices: iwm0" The HW probe I performed for the Intel NUC computer is here. https://bsd-hardware.info/?probe=c55f468566 The wifi in this particular NUC wasn't suported until FreeBSD 13.0 (You can see here https://bsd-hardware.info/?id=pci:8086-31dc-8086-02a4)
The model of the Intel NUC in question is 7CJYSAL or 7CJYH
Can you by any chance try iwlwifi and see if that works on a latest stable/13 or main or once out 13.1-RELEASE (feel free to try RC1 as well)
I just checked the PCI IDs again and while they are listed in iwm(4) this particular version needs special treatment. iwlwifi(4) should support this.
