Hello,
We are testing a mesh before deployment. At the moment it drops out every few mins. We had the same problem with a mesh we previously set up and in the end, after getting advice from AirHeads, we disabled VHT & set ARM to 'maintain' which stabilised things.
The g-radio is disabled on both Portal and Point.
When setting up the new mesh I cloned the existing groups from our first mesh, but it seems as if some of the settings haven't taken hold. When the mesh is up this is the output of 'show ap mesh top':

and this is the output of 'show ap mesh neighbors ap-name f0:5c:19:c3:32:1c':

As you can see VHT is still listed under HT-Details. Also what are the two entries here, obviously one is the MAC of the portal, I'm assuming the two listed under MAC are the Point, but why are there 2?
The mesh currently only stays up for a short time (a few minutes), it's possible we also have the APs rather close together which may not be helping, currently 4 metres or so (is there a minimum distance you recommend?).
I've attached the config of the mesh groups and radio groups, let me know if you need any others.
Thanks in advance
