su testrflink <suid>

This command also checks the integrity of the wireless link from the standpoint of over-the-air packet loss. 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 AP, 20 packets received back at AP, and 20 packets received at the SU. Any results other than 20..20..20 indicates a performance problem, most likely due to interference or inadequate signal to noise ratio. For thorough results it is recommended you run the command repeatedly for at least 1 minute or more to determine if packets are passing without error consistently over time. This command will give results without the help from ARQ. Note: This test does not provide as much detail as the linktest command.

The “r” is used in this command to repeat the RF link test repeatedly until the user terminates the test by hitting SPACE ENTER.

Example:

#> su testrflink 1 r

Press [space] then [enter] to stop [len] 1512

[suid] 1

[5] ...........[AP Tx] 20 [AP Rx] 20 [SU Rx] 20 Success.

As another example, a result of 20..10..18 would indicate 20 packets sent from the AP, 18 packets received at the SU, and 10 packets received back to the AP. These types of results may be caused by Fresnel zone infringements, interference, or multi-path.
