Frequent heart beat losses on unleashed meshed network

For APs to maintain Mesh, they must see each other at >= 25 RSSI.

You can review the AP's support info, for client details which will show the other AP as a client.

Mesh AP have very low RSSI value to establish a mesh connection to the root AP. The optimum value suggested to have is 30 - 35 RSSI.

We usually look at the mesh-topologie screen within the AP menu and aim for a signal strengt of 25 minimum but preferably higher. In reply above you are suggesting a different method to find out the signal strenght but to be honest, I don't know were to find this information

Hi Sander,

This information can be found in the support log of an AP.

You can also access this information from the command line.
'get mesh' will display what you're looking for.

Can you please confirm that the signal strength of 25 that you're aiming for is a dBm value?

Phil.
