[atlas] shared fate for my two probes

My V3 probe would semi-randomly drop connection for a few minutes
before I moved it to another part of the apartment. Sounds kinda stupid,
I know, but are your probes physically located near each other? Can
you move them? Could be that they are more sensitive to stray RF
than your other equipment.
