Actually it seems that wifi reception in my room, combined with the low
yield of the chip antenna on the cubietruck is actually so bad that
it is possible for the list to show up empty.

I've verified this with the android image on the cubietruck, and after
moving the cubietruck around a bit to get better reception I now have
things working :)

I do wonder about the brcmf_fil_cmd_data errors though, IMHO those should
be avoided if possible.
