connamn incorrectly shows no WiFi services

[Napoleon-BlownApart]

On a NAO v4 running Naoqi 2.1.14.3 with with the 2.6.33.9-rt31-aldebaran-rt #1 SMP PREEMPT RT kernel, using a Ralink RT2870/RT3070 USB wireless adapter, connman services shows no WiFi services when there are definitely two, not hidden, networks present that have both been configured and connected to before.
In fact, the NAO disconnected from one of the networks for some reason and now can't see it, the same network from which I'm posting this issue.

What is the cause of the problem?

uname -a gives: Linux sonic 2.6.33.9-rt31-aldebaran-rt #1 SMP PREEMPT RT Thu Aug 27 21:42:34 CEST 2015 i686 Intel(R) Atom(TM) CPU Z530 @ 1.60GHz GenuineIntel GNU/Linux
