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 both the AP
and the SM.
MODULE HAS LOST OR DOES NOT ESTABLISH RADIO CONNECTIVITY
If there is no wireless activity, follow this:
Procedure:
1
Check that the AP and SMs are configured with the same Frequency Carrier. Also, if operating
in a region where DFS is required, ensure that the SM’s Frequency Carrier List contains the
frequencies configured in the AP’s DFS Alternate Frequency Carrier 1 and DFS Alternate
Frequency Carrier 2 fields.
2
Check that the Channel Bandwidth is configured the same at the AP and at the SM
3
On the AP, verify that the Max Range setting is configured to a distance slightly greater than
the distance between the AP and the furthest SM that must register to the AP.
4
Check that the AP’s Synchronization Source is configured properly based on the network
configuration.
5
Verify the authentication settings on the AP and SM. if Authentication Type is set to WPA2,
verify that the Pre-shared Key matches between the AP and the SM Preferred AP List
6
Check that the software at each end of the link is the same version.
7
Check that the desired AP’s SSID is configured in the SM Preferred AP List.
8
On the SM, check the DL RSSI and DL CINR values. Verify that for the SM installed distance,
that the values are consistent with see
on page
9
Check Tx Power on the AP and SM
10 Check that the link is not obstructed or the AP/SM misaligned.
11 Check the DFS status page (Monitor, System Status) at each end of the link and establish that
there is a quiet wireless channel to use.
12 If there are no faults found in the configuration and there is absolutely no wireless signal,
retry the installation procedure.
13 If this does not work then report a suspected AP/SM fault to Cambium Networks.
