Mesh Link Troubles

    I have a point to point link via a 3800 controller and two AP-175's with directional pad attenas

     

    Link quality is 32 

    Tx/Rx is only showing 65/65

     

    Pings from the LAN out to the far side of the point are spotty at best with several timeouts.

     

    I don't believe the antennas are out of alignment as link quality is still good at 32.

     

    I have rebooted both portal and point AP's but problem remains.

     

    Anything else I should try?

    Here are some troubleshooting steps for Point-to-Point Network 

     

    During the configuration or staging of a mesh network it is possible that you could have some
    issues with forming mesh links between the nodes or other setup issues. Some of the common
    reasons for this include:
      - Configuring a different Mesh-ID on the two nodes.
      - Mismatch in the mesh security configured on the two nodes.
      - Radio on either of the nodes is down
      - Auto WDS is disabled on a radio.
    In the attached document, you can try some of troubleshooting procedure to figure out the
    reason for the downed link and fix it. 
      - Checking active links on each node.
      - Verifying mesh configuration on each node.
      - Getting device list within same Mesh-ID
      - Getting radio status of each radio on each node
      - Getting neighbor nodes
      - Help to align antenna in real deployment

    A couple of things to be sure of:
    Use 5 Ghz for backhaul
    Ensure power is set to max for backhaul.
    Ensure there's no co-channel interference causing poor link speed. I've had that happen where the channel was busy 90% of the time and the mesh link wouldn't come up because of that.
