After running about 54 minutes I got:

 counts      time (ms)
300272 3245606 signalInfo rssi=-63
300273 3245616 signalInfo rssi=-63
Error: wpa_supplicant DBus error in signalPoll: Did not receive a reply.
Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout
expired, or the network connection was broken.
