No, I don't think range is much of a problem. XOs are pretty good at
picking up wi-fi signals (dual external make a big difference).
The main problem is capacity of the network. School wi-fi networks are
typically not well-geared for every child actively using the
connection at the same time.
Is it the capacity of the WiFi network or the Internet link?
Are they on a Satellite or Terrestrial (Wireless or Fibre) Internet
Connection?
Is there a GSM/4G network available?
Small/remote communities, through necessity, tend or at least need to be
better integrated - is there a library, hot spot provider in the vicinity?
It seems one approach to increasing wireless capacity is to reduce the
size/range of cells and increase their number. eg lightRadio

So, maybe multiple routers connected via ethernet. May also be worthwhile
testing different Antenae.

My experience with D-Link products and support is terrible, so I no
longer consider them.

Is distance/coverage an issue - access beyond classroom/school?
Have you checked out the D-Link range?

With the Sugar environment, do all laptops connect to the access point or
is
it a mesh where traffic is relayed or tunnelled through one connection,
and
it is only the internet requests that go through the access point?
XOs can connect via ad-hoc or through an access point. Ad-hoc requires
one XO to act as the hub for the others, but only scales to 5-10 XOs.
An access point is needed beyond that. Once you get beyond 20-30 you
should start thinking about implementing an XS School server, which
runs an ejabberd instance to manage the XMPP (jabber) traffic.
XO-1s had mesh capabilities in hardware, but this no longer applies in
the XO-1.5 and XO-1.75. Ad-hoc has taken its place.
