I didn't have time this morning to grab the output of iwconfig, it'll have to wait until tonight. I did see that the TX power was 20 dBm. However all RX related levels were 0 (noise, signal).
I tried rfkill. It said that all the switches were on. Running the command mentioned in the Info for rfkill didn't change anything.
Is it possible I need to change channels? The channel wasn't listed in the example for wpa_supplicant.conf. Does the software auto-scan all channels?
If WEP doesn't require any WPA stuff, what would be the correct approach to getting wifi to work? I saw that WEP was listed in the options for networks under wpa-gui.
