My problem is that wlan0 doesn't show up as an interface. Despite having
added wlans_zyd0="wlan0" to my rc.conf file, my interfaces are as shown
below:

nassy# ifconfig
msk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=118<VLAN_MTU,VLAN_HWTAGGING,TSO4>
        ether 00:13:d4:07:c7:2e
        inet 10.0.1.199 netmask 0xffffff00 broadcast 10.0.1.255
        media: Ethernet autoselect (1000baseT <full-duplex,flag0,flag1>)
        status: active

        options=8<VLAN_MTU>
        ether 02:11:d8:37:35:aa
        ch 1 dma -1

        inet 127.0.0.1 netmask 0xff000000

        ether 00:21:79:c2:44:82

        status: no carrier

As you can see, there is no wlan0. So, what might I be missing to actually
get wlan0 setup? Everything I've found just mentions the rc.conf stuff,
which I've done.
