Troubleshooting the radio link
This section describes how to test the link when there is no radio communication, when it is
unreliable, or when the data throughput rate is too low. It may be necessary to test ODUs at
both ends of the link.
Module has lost or does not establish radio connectivity
If there is no wireless activity, follow this:
Procedure:
1
Check that the ODUs are configured with the same Frequency Carrier.
2
Verify the authentication settings on the ODU. if Authentication Type is set to WPA2, verify
that the Pre-shared Key matches between the ODUs.
3
Check that the software at each end of the link is the same version.
4
Check that the desired Master ODU SSID is configured in the Slave Preferred Masters List.
5
On the Slave ODU, check the DL RSSI and DL CINR values. Verify that for the ODU installed
distance, that the values are consistent with the values reported by the LINKPlanner tool.
6
Check Tx Power on the ODUs
7
Check that the link is not obstructed or the ODUs misaligned.
8
If there are no faults found in the configuration and there is absolutely no wireless signal,
retry the installation procedure.
9
If this does not work then report a suspected ODU fault to Cambium Networks.
