I found these advanced User's Guides to be very helpful, that and the code
in the various arduino projects had me up and running in a weekend.
My main issue was that the on board Chip Antenna (extant = 0) did not work, would not scan nearby networks.
Quoting from page 19 of the Roving Networks User Guide.
]set wlan ext_antenna <0, 1> determines which antenna is active, use 0 for chip antenna, 1 for UF.L
connector. Default = 0. Only one antenna is active at a time and the
module must be power cycled after switching the antenna.
Only by switching to the external antenna (with nothing attached to the socket I might add) did I get repeated and solid
connectivity to both my own wifi networks, but also my neighbours.
The Roving Netwokrs App Engineer suggested perhaps the wifly module has a bad or broken ground - has any one else
reported a problem with the chip antenna
Two additional items to note - tje RN-171 is a smaller, lower power radio with programmable transmit power. Will be nice
to see these show up in the next rev of the wiFly whield.

AND
RovingNetworks is working on a multi-connection protocol (up to perhaps eight connections). This will be a firmware upgrade
to the RN-131. In designer testing now, expect Beta test FW in a few months.
