How to test an WR44V2 step by step.
Page | 31
Connect the ADSL cable to the “Golden DSL testing unit”. Wait for it to “train” and then issue the
adslst command:
Modem Status: Showtime
Link Uptime: 0 Hrs 0 Mins 35 Secs
Firmware Version: SW 1.11
Operational Mode: ADSL2+ Annex A
Remote Vendor ID: IFTN
Est'd Loop Length (ft): 9995
Downstream Upstream
-------------- --------------
Speed (kbps): 5668 839
Attainable Rate (kbps): 6048 840
Relative Capacity (%): 93 99
Attenuation (dB): 49.7 32.8
Noise Margin (dB): 1.4 5.8
Output Power (dBm): 12.4 11.9
Cells: 0 N/A
FEC: 1726 0
CRC: 5 0
HEC: 226 0
OK
Ensure the status is “Show Time” (to confirm it has trained up) and then make a note of the
Operational Mode
Downstream speed
Upstream Speed
Attenuation
Noise Margin
Firmware Version
Ensure the operational mode is correct for the line (e.g. if the fastest mode the line supports is ADSL2+
then this should be the mode that is negotiated.)
It would be wise to issue the following command:
adsldrop
This will cause the router to re-train.
Then re-check the output of the following command after it re-trains:
adslst
Perhaps take an average of 5 readings (dropping the link each time) to get a feel for the range of train
up speeds on this line.
