We will come back to you ASAP.

Hello again Zdrowie,

I found this solution. Can you tell us if it helps, please?

You are experiencing an issue with FortiManager version 7.6.45 where the internal antennas of the FortiGate 40F (FWF40F) are not showing an online status. Instead, only one internal antenna appears online, while the others show an "unknown" status. This issue does not affect external FortiAP antennas, which are showing an online status normally.

Known Issues and Resolutions

Based on the provided context, there are no specific known issues documented for FortiManager version 7.6.45 related to the internal antennas of FortiGate 40F. However, there are some known issues in FortiManager related to AP Manager and device management that might be relevant:

• AP Manager Issues: There are several known issues with AP Manager in different versions, such as unsupported channel errors, missing bands, and issues with AP profiles. These might indirectly affect how antennas are displayed or managed.

• Device Manager Issues: There are known issues with device management, such as incorrect time displays and configuration errors, which might also contribute to the problem.
  
  

Troubleshooting Steps

1. Verify Configuration: Ensure that the configuration for the internal antennas is correct in both FortiManager and FortiGate. Check for any discrepancies or misconfigurations.

2. Check Firmware Compatibility: Ensure that the firmware version on the FortiGate 40F is compatible with FortiManager 7.6.45. Sometimes, firmware mismatches can cause display or management issues.

3. CLI Verification: Use CLI commands on the FortiGate to verify the status of the internal antennas. This can help determine if the issue is with the FortiManager display or the actual antenna status.

4. Review Logs: Check the logs on both FortiManager and FortiGate for any errors or warnings related to the antennas.

5. Contact Support: Since you have already opened a TAC case, continue to work with Fortinet support for a resolution. Provide them with detailed logs and any additional evidence you have collected.
