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