Mesh APs won't connect or bad connected

Can anybody help with my problem?

We have about 300 Aerohive AP130 and a handful von AP150 and we need to mesh in
certain locations.

The first AP is connected by wire and works fine. The next AP is mostly a
mesh-AP because of lack of ethernet or next building(!). We use Hivemanager
V8.2r2c, tried to update to XIQ, but we cannot buy the license, so we go back
to Hivemanager. Anyway: I manage the config of the APs by CLI. APs are running
firmware 10.3.r3.

At least from the latest firmware the mesh is not working as desired. Some APs
won't connect or connect badly, althougt they are visible in "show acsp
neighbor". While there are about 80 locations spread wide I cannot inspect the
position of the APs nor can I change the mounting position, since it worked
with old firmware 8.2r6. But we had to upgrade...

Can anybody say, what I can do to get the mesh working?

Aerohive is our hive with strong PSK

Only wifi0 is in the hive, ‘cause I don’t see the AP xxxx:yyyy:c610 on wifi1, and there is a third APs, think “behind” 03

We need mesh!

Pings to the meshed APs are terrible!

Hi Frank, not sure if this is going to be causing your Mesh issues, but 10.3r3 is not supported with HiveManager Classic (per the release notes for 10.3r3). Otherwise we have a guide for CLI commands for troubleshooting Mesh, and a larger guide for setting up Mesh in general that also includes things to check when the connection is not setting up properly. 

Hi Sam,


this PDF Mesh in General is “only” how to deploy and some hint howto position. And what not to do, so in line it would be a bad idea … and so on…

These Commands in troubleshooting mesh are helpful, but not enough.

See: I have some APs I see as my hive (MAC and Hive-Name) but it will not connect at all?! RSSI is “not bad” but why is it not up and working?

Thank you for your feedback on those articles. I’ve expanded the CLI troubleshooting article a bit, mostly in the “show hive <name> neighbor” section. I also added a section on “show amrp neighbor”, some mesh debugs that I’ve found useful in the past, and some general things to check for Mesh at the end of the article. If you don’t find anything with those additions, I’d recommend opening a support case for this so you can work directly with one of our technicians. If you’d like to try to troubleshoot further via this thread, I have a few questions/suggestions:


  1. Can we move to a firmware version supported by HiveManager Classic 8.2r2? You can see in the release notes which platforms that firmware version will be compatible with. Please let me know what version you move to as well. 
  2. What is the RSSI value for the neighboring mesh AP? 
  3. Are you seeing the Hstate “Auth” with the command “show hive <name> neighbor”?
  4. Are you seeing a TWO-WAY cost with the command “show amrp neighbor”?
  5. Are the APs on the same channel? 
  6. Is there a clear line of sight between the portal AP and the remote (no ethernet) AP?
  7. If you put both APs within 10-20 feet of each other, do you see the same behavior or does the mesh connection come up?
