Thank you, thank you, thank you.  This gives me a 'starting point'.

To 'scan-wifi', the "bad" XO-1s return lines like this:

  RSSI:  0 SSID:              Channel 1
   ...
  RSSI:  0 SSID:              Channel 1
  RSSI: 41 SSID:              Channel 1

To 'scan-wifi', the "good" XO-1s return lines like this:

  RSSI:  0 SSID:              Channel 1
   ...            <more such lines than the "bad" XO-1s>
  RSSI:  0 SSID:              Channel 1
  RSSI: 85 SSID:  2WIRE241    Channel 11


Note that both the "bad" XO1-s and the "good" XO-1s __will__ connect via
the (non-adhoc) mesh interface -- to me that says the silicon is working
-- though I do not know if the AP radio signal in the "bad" XO-1s is too
attenuated (bad antenna connection?) to be detected.


Thanks again,  mikus
