Using firmware version 2224-4894f42, under "neighbor status" we see some links the show "active - exposed" or "idle - exposed". The help file explains active and idle but does not reference "exposed". What does exposed mean?
Thanks, Mike ab4yy

active/idle - exposed...meaning?

Short answer: An exposed node hears too much. CSMA prevents it from sending DATA or ACKS due to co-channel occupancy.
I hope this helps, Chuck
Thanks Chuck.
The problem points to a mountain node that several other nodes (a few miles away) are connected, and only on the 2.4 GHz (-2/10) node. We are trying to move more folks to 5 GHz to help. But possibly other non-ham Wi-Fi is also being heard there. We are also turning off other 2.4 GHz nodes that are not being used or are too weak into the system.

It's explained in the online documentation here: https://docs.arednmesh.org/en/latest/arednNetworkDesign/channel_planning.html#hidden-and-exposed-nodes
Thanks Steve. I must have missed that when I did a search in the docs for "exposed". I see it now. It is a helpful explanation.
