FreeBSD 11 doesn't load firmware to wifi card. Worked in FreeBSD 10.3.

Thank you Andriy, that solved my problem and made me recheck my rc.conf 
which should already be configured to start the interface automatically. 
I then found an embarrassing misspelling. I had written rum0 instead of 
run0 in the line that reads 'wlans_run0="wlan0"'. I knew I had done 
something stupid and I apologize for the noise.

Vital information that is now memorized. Thank you once again for your help.
