Hi,

From verbose boot:

iwn0: <Intel Centrino Advanced-N + WiMAX 6250> mem 0x80400000-0x80401fff at device 0.0 on pci2

and:

# pciconf -lv | grep -A3 iwn
iwn0@pci0:2:0:0: class=0x028000 rev=0x5e hdr=0x00 vendor=0x8086 device=0x0087 subvendor=0x8086 subdevice=0x1301
    vendor     = 'Intel Corporation'
    device     = 'Centrino Advanced-N + WiMAX 6250 [Kilmer Peak]'
    class      = network

BUT:

# ifconfig iwn0
ifconfig: interface iwn0 does not exist

What am I missing?
