Hi all.

On my old Hyundai laptop there seems to be no WiFi interface at all: there's no
wlan0 entry in ifconfig's output:

# ifconfig -a

, and also

shows up - as far as I understand - nothing about WiFi.

Please help abilitate WiFi connection on that PC.  With google I couldn't work
it out.

Thanks,
