wrote this program to monitor the upstream and downstream SNRM and
attenuation on a Linksys wag54gs. Unlike other tools
the program is capable of continuously monitoring your ADSL line status
and graphing the results. The monitored SNR can be saved as a
.csv file, which includes timestamps for each event, and although by
default the graph shows the SNR for the total period monitored, it can
be zoomed in by using the scroll wheel and scrolled left and right.
The graph can also be saved to the clipboard or saved as an
file, which is useful for diagnostic purposes.
above is a saved graph showing several hours monitoring, with two drops of sync. The next graph
is zoomed in to show the first 20
Screen shot of WAG54GS Status monitor.
The program is quite simple to set up, but the router needs an
adjustment in its settings to allow the program to connect.
do this, log into the wag54gs and go to the administration page.
The second item down is for the SNMP settings. You need to
in the name box, and public
into each of the community boxes, the rest of the settings can be left
blank. Next, put a dot in the little box next to enable, then go to the
bottom of the page and save
the settings. At this point the router will reboot.
Thats it, its now set up !!
now we need to tell the monitor program how to connect to the router.
In the IP Address box, put the address of your router (this
defaults to 192.168.1.1 which is the default address for the router).
In the community box, put public,
or whatever your get community name is (if you have followed these
instructions it will be public.
Thats it, if you wish you can change the default monitoring
from 5 seconds to a value more suitable to you. e.g. 1
seconds,30 seconds etc.
Click start and the program will monitor your line statistics.
This program requires Microsoft .net framework 3.5. If you do
not have this, the installer will prompt you to download it.
beta two version is now available to download. Updates
support for firmware V1.01.01 & V1.01.03, monitoring time
and sync up time now displayed and recorded in logfile.
session bytes in/out now displayed. DSL and PPP status now
displayed. Recorded data (including graph) can be cleared.
This program should not affect your router or internet conection as it
reads from the router. However in the unlikely event of
going wrong I am not responsible for any issues arising from the use of
