I was troubleshooting a situation where at least two XO-1 systems would
only rarely associate with an AP (and often had no 'eth0').  Despite
trying everything under the sun, I could never determine the cause.

>From my experimenting, whether I had mesh enabled or not did not make a
difference in this.  I have since reflashed those systems with newer
builds - and am no longer seeing the "missing 'eth0'" situation.
Perhaps the software in the problem systems had gotten corrupted.

What I __still__ cannot depend upon is for every XO-1 to reliably
associate with an AP.  A symptom that I frequently observe is that
'iwlist eth0 scan' (as root) does not show the radio signals that other
XO_1s do show.  [Wireless debug trace shows the scan is being invoked.]
Looks to me that I will be spending lots more time pursuing "how come".

Bernie, thank you for your help,   mikus
