  8. Stability improvements for crashes and platform performance.
  9. Cloud connectivity improvements.
  10. Improved fiber port stability on B11.

Radio (PHY and MAC)

  1. Improved B11 link reliability for scenarios where beacons are missed due to interference.
  2. Improved the responsiveness of aiming mode.
  3. Fixed an issue where Channel/Power changes on AP caused “Error unable to load data" on device UI.
  4. Fix a condition where combined spectrum looks incorrect.
  5. Improved performance for B11 links, including across temperature.
  6. Fixed an issue where target level and transmit power are shown incorrect on the B11 Station’s UI.

Known Issue
If both the backhaul radios are attached to Cisco 3550 or 3750 switches and the Dynamic Trunking Protocol on the switches is turned on, connectivity to device’s management IP may fail. The workaround is to turn off the Dynamic Trunking Protocol on the trunk port.
