I don't like the way this SNRM seems to be varying.
On the assumption that you have that filter, plug your phone (preferably a corded one) in there and do a Quiet Line test 17070 option 2.
If you hear any crackling or other noises, I would power off the modem/router and check your connections on the IDC terminals and make sure they are fully pushed home (down) in the terminals (with the tool).
It would also be a good idea to run
RouterStatsLite for a while to see what this line is doing.
OK here is my setup guidance for RouterStatsLite for your line at present-
Create a folder some where convenient - ideally in root (C:/) so there's no privilege issues. You can create another folder somewhere if you want to save the Captures and Log file in a different one.. Below is my suggested setup -
Do not click on the Start Arrow, bottom left, yet! But it ought to automatically open at the Setup tab the first time anyway. Maximise the RouterStats Window.
First go to the Setup tab, then the Router tab and select your modem/router.
The URL tab should show the path where you get the stats, tick the box for the full path.
On the Login tab, there should be a tick in the box 'Router requires you to login'
The Username will show the default one, which you may have changed (admin for the 582n).
The password may be a default one (unless changed by you) or the one provided with the router originally - note, this is not your broadband password.
On the Graph tab, initially, untick the Adjust axis automatically boxes, you may want to alter the settings later. For the Noise Margin, set the Maximum to 9 and the Minimum to 0. For the Connection Speed set the maximum to 3000, minimum to 0. Tick Noise Margin Vertical Axis 'Plot average value of previous 50 points', but not the Connection Speed average. Remember to click Apply on both boxes (and any other time you make changes).
In the Sample Interval box choose 'Sample router every 10 seconds' and 'Points per page 720'
Next, go to the Capture tab. Define the folder where you want to save the Captured graphs, this could be the folder where you've installed RSL or another of your choice. Tick 'Capture noise margin graph images', also tick 'Capture part-graphs when RouterStats-Lite closes'. Tick the other two graphs if you wish. I'd tick the sync speed in the current situation.
Go to the Log tab, type the filename you want for the log, e.g. RSLite.txt & then browse to the folder you want to save it in, suggest the same as the graphs, when selected, the full pathname will appear in the box. Comma separated values is selected by default, and log every 1 sample.
Nothing to change on the Appearance tab.
On the System tab, tick 'Minimise to system tray', 'Prompt before closing', 'Show noise margin on tray icon' & 'Show tooltip hints'. If you want the Ping plotter, tick that as well. On the PIng tab you need to specify the IP address to ping - try 212.159.13.49 - one of Plusnet's ntp servers.
You can now go to the Noise Margin tab and click on the green Start button. You should see a Green Camera icon on the LHS showing capture is active.
If you right click on the graph, the drop down menu shows a tick against Capture. You will also see some other handy options you can use at any time.
There is minor bugs in various recent versions where the ping is not always being Captured automatically, so if you want one, do a right click Capture now, also the Ping Capture setting is not being retained on Close. It also saves blank graphs when it's not running for every config change and extra graphs when it is running, so check and delete those not required taking up disk space.
Maximise the RouterStats window before Minimising it to the Tray. This ensures captures are at the full screen size showing the most detail (as far as the SNRM is concerned).
HTH.
NB. For other readers, if you don't select the Automatic Graph settings, choose values to suit your own line conditions.
