Just Joined from Virgin but slow speeds
Thanks for pointing out the graph was yesterday ejs, I was about to post (reply #44) that it might have been swapping to the 7800N that caused DLM to act, if it hadn't been done gracefully, but that was before Matthews post which I then saw and deleted that part of my comment thinking it was today which was rather daft as I'd already posted yesterday about that 
However the Target was 9 db before that not 6db.

Some poor individuals have some, mainly Fibre - BT network problems 
Download RouterStatsLite from here. I don't know which version of Windows you are running, but whichever, I'd still install it in your Root directory (C:\) so when prompted by the installer change it to C:\ so it installs to C:\RouterStats-Lite this should avoid any issues with permissions/privileges.
You can create another folder somewhere if you want to save the Captures and Log file in a different folder from the program (that is/would be my choice), perhaps in your Shared Documents, maybe call it RSLdata.
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 the modem/router, select Billion Bipac 7800N (not the LLU one)
The URL tab should show the path where you get the stats, tick the box for the full path if applicable.
On the Login tab, there should be a tick in the box 'Router requires you to login' for most modem/routers.
The Username will show the default one, which you may have changed.
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, leave ticks in the Adjust axis automatically boxes, you may want to alter the settings later. Tick Noise Margin Vertical Axis 'Plot average value of previous 50 points', but not the Connection Speed average. Remember to click Apply on any you change (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 in Shared Documents - RSLdata - 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. (Note - the Ping capture setting is not saved on RSL close).
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 options you can use at any time, (similar on the other graphs) but Tick 'Plot Upstream Noise'.
There is a minor bug in the last few versions where the ping Capture is not done on close, so if you want one, do a right click 'Capture now', also the ping capture settings are not retained on closure of RouterStatsLite (RSL).
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.

OK the graph is showing a distinct steady regular pattern of interference. The sort of graph you should see at this time of day, I'll attach for you.
The interference will be what's causing the regular errors and this is what DLM will be responding to. It's now a case of finding out what's causing it. Usually these things are caused by faulty or poor design switch mode power supplies or other electronic/electrical apparatus.
Have you had any other new equipment lately apart from the modem/routers obviously?
Also need to check the things you have, which are the usual suspects - Sky boxes, TV sets, Monitors, mobile phones & chargers, low voltage halogen lighting PSUs, Compact Fluorescents, LED lamps, the list goes on......
The easiest way to check your own stuff to start, is process of elimination, start by turning off your monitor for say 5 minutes. When you switch it back on see if the plot had changed, otherwise then turn off everything that you don't need on at this moment and see if the SNRM line goes flat. If it does, then switch things back on one at a time until you spot a culprit.
On the example graph, the RHS is what you'd hope to see in daytime a very few occasional little (0.1db) steps up and down. On the LHS of that graph you are seeing the tail-end of the night-time/dawn higher levels of noise (it's levelling off), which is much greater after dark.
Edit: forgot to mention that the flat US SNRM plot is typical of 20CN and is nothing unusual.
