Hi,

The issue of sugar prompting users to enter wifi passphrase after a
connection is broken and is re-established[1] has been in Sugar/OLPC
for some time.

The purpose of this email is to understand the causes of this:
* Bad wireless access point
* Proximity to a wireless access point
* Something not working properly on the XO laptop
** Driver?
** Firmware?
** Something sugar specific?

Talking with deployments, this is an annoying little bugger, because
everytime it happens, the teacher has to run over to the kid's laptop
and enter the passphrase. We are getting some reports that this flakey
*might* be happening more often with dx3 (and following from that
11.3.x) builds.

Therefore I'd like to understand the causes of this and what can be
done to address it (at various levels: XO, Sugar, Wireless Access Points)
