Hi Kel,

I'm just getting started with wireless networking on Linux, so I don't
really know what I'm doing yet. But I'll do my best to help debug
this.

Once I bring the interface up, I can run "iwlist ath0 scanning" and it
completes, and finds my access point.

ath0      Scan completed :
          Cell 01 - Address: 00:06:25:3C:28:B9
                    ESSID:"My WLAN"
                    Mode:Master
                    Frequency:2.437 GHz (Channel 6)
                    Quality=39/94  Signal level=-56 dBm  Noise level=-95 dBm

                              48 Mb/s; 54 Mb/s
                    Extra:bcn_int=100
                   
Extra:wpa_ie=dd160050f20101000050f20201000050f20201000050f202

Let me know if you'd like me to try anything else. I'm off to read
about how to set up WPA PSK.
