linktest <su#>
This command checks the integrity of the wireless link from the standpoint of performance. AP will send 500 large packets to the SU
and the SU will return what it receives to the AP. Small numbers of errors are inconsequential. A perfect link (without dropped
packets) will yield average throughput over 3,000 kbps. If heavy packet loss occurs it may be caused by interference or multi-path.

su testrflink <su#> This command also checks the integrity of the wireless link from the standpoint of 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 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, 20 packets received at SU. Any results other than 20..20..20
indicate lost packets, most likely due to interference or inadequate signal to noise ratio.
The “r” is used in this command to repeat the rf link test repeatedly until the user terminates the test by
hitting SPACE ENTER.
