[Testing] [OLPC New Zealand] os873 on XO-1.5 and os873 on XO-1 -07/15/2011

[Samuel Greenfeld]

XO-1.5's do not have Mesh networking support, so they use 802.11 Ad-hoc
networks.  XO-1's default to Mesh networks at the moment for compatibility,
because that is what they historically have done.

Once an XO-1.5 starts an Ad-hoc network, the XO-1's will spot that network
within a minute or two, and use the same Mayan numeral as the XO-1.5 to
indicate its presence.  If all the XOs leave an Ad-hoc network it
disappears; but Network Manager/Sugar cache its presence for a while in case
a scan accidentally missed a network.

When an XO-1 sees an Ad-hoc networks they are all filled in as "occupied",
because an XO-1 does not show the unfilled variants to allow an XO-1 to
start them.


This behavior has been around since OLPC build 10.1.3 (860) & Sugar 0.90,
and is described at http://wiki.sugarlabs.org/go/Features/Ad_hoc_Networking

I believe XO-1's can be adjusted to default to Ad-hoc as well if desired,
but Simon would be the authority there.
