FreeBSD 15 doesn't recognize Intel Wireless AC 8260 card

My OS was 14.3 and did online upgrade to 15.0 when released. The upgrade didn't succeeds because the wireless card is not detected by the OS.
It was working fine on 14.3.
Now, I did full installation of 15.0: the same behavior still happen: the wifi still not working.
If someone can help?
 
on 14.3, it was "iwm"
on 15.0, it becomes "iwlwifi"

Try /boot/loader.conf
Rich (BB code):
devmatch_blocklist="if_iwlwifi"
See if it is enough to attach the iwm(4) driver to the device, check dmesg(8), or pciconf -lv | grep -B 3 network, check if the firmware is loaded: kldstat(8).

If not, try adding
Code:
if_iwm_load="YES"
besides the devmatch blocklist.

If the iwx(4) driver attaches, put it on the blocklist as well, space separated besides iwlwifi.
