su linktest <su#>

This command checks the integrity of the wireless link from the standpoint of performance (throughput) and over-the-air packet loss. The AP will send 100 (1600 byte) packets to the SU, and the SU will return the packets it receives to the AP. A perfect link (without dropped packets) will yield average throughput of 3,000 kbps. If heavy packet loss occurs, it may be caused by interference or multi-path.

Example:

#> su linktest 88

su testrflink <su#>

This command also checks the integrity of the wireless link from the standpoint of over-the-air packet loss. Relative to the linktest command, however this test does not provide as much detail. In this test the AP will send 20 large (1512 byte) packets to the SU, and the SU will in turn send the same 20 packets back to the AP. The expected result of an error free link is 20..20..20, indicating (in the following sequence) 20 packets sent from the AP, 20 packets received back at the AP, and 20 packets received at the SU. Any results other than 20..20..20 indicate a performance problem, and are most likely due to interference or an inadequate signal to noise ratio. For thorough results, it is recommended that you run the command repeatedly for at least 1 minute or more to determine if packets are passing without error consistently over time.
