[XSCE] Re: [support-gang] [UKids] "XO-1 classrooms" don't reliably connect to many/most Wifi AP's

I have to disagree.

I do not believe that any conventional router will work properly with XO-1s
while the current mesh functionality is enabled in the XO-1 if the AP is
subject to rigorous testing.

It is clearly evident from our tests that even if only one XO-1 has the
current mesh facility enabled, it will disrupt the operation of every other
XO-1 in the vicinity which is trying to connect to any AP. The disruption
is readily seen with James's beacon time monitoring script.

By comparison, later model XOs operating concurrently in the same
environment are not disrupted at all by the presence of the XO-1 running

The unwanted interaction is between XO-1s, not with the AP or with other XO

I believe the solution has to be found in the XO-1.

The initial, brute force, solution is to switch off the mesh capability
completely, which results in reliable operation of the XOs in connecting to
the AP.
