Thanks for the reply!
You are right it's a FROM/TO relationship, as when I hover over the little arrows, a small popup says as much.
My guess is exactly the opposite - the 7762 has external omni antennas, so I would think the signal FROM the 7762 is a tad stronger at the receiving end (WEAVER) than from WEAVER to the 7762.
It would be nice if Ruckus can clarify this. That 5% on MAINTENANCE SHOP concerns me, but without knowing what I'm seeing, it's hard to try to fix it.
