I think it might be an idea to do some more automated continuous monitoring, if you want to have a go using a program called RouterStatsLite which many of us use from time to time.
If you download and install
RouterStatsLite. I'd download the zipped version, and unzip it to a directory created in root ie in C:\ (not Program Files). Perhaps call the folder RSLite.
You can create another folder somewhere if you want to save the Captures and Log file in a different one (that would be/is my choice). May be call it RSLdata and put it in your Shared Documents folder.
Below is my suggested setup (for you) -
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 - Thomson TG582n / TG587n
The URL tab should show the path where you get the stats.
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 - for the 582n it's the serial number beginning CP.......
On the Graph tab, initially, leave the Adjust axis automatically box for the Noise Margin, For the Connection Speed, untick the Adjust axis automatically & set the maximum to 5000, 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' and click Apply.
Next, go to the Capture tab. Define the folder where you want to save the Captured graphs, this could be the folder I suggested earlier 'RSLdata' or another of your choice, you can browse to it to make life easier. Tick 'Capture noise margin graph images', & 'Capture connection speed graph images', also tick 'Capture part-graphs when RouterStats-Lite closes'. (btw if you ever decide to use it, the Ping capture & setting is not saved on RSL close - note).
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. Also tick the 'Plot Upstream Noise'. You will also see some other options you can use at any time, similar on the other graphs.
There is a minor bug in the last few versions where the ping capture & settings are not retained on closure of RouterStatsLite (RSL).
If at any instant you want to Capture any graph that's not scheduled, do a right click Capture now
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).
You can create shortcuts to the exe file and to the folder for your captured files and put them on your desktop if you wish.
HTH.
