In my case, there appear to be no other radio signals present.  If there
is network congestion, the XOs are generating it themselves.

What I found interesting (by hovering over the respective icons in
Frame), was that the SAME IP-address was assigned when connecting to the
ad-hoc wireless network as had been assigned (before there was an ad-hoc
network) when connecting using the mesh icons in Neighborhood View.

In my case, I'm connecting XO-to-XO.  There is no firewall.
