It would be most beneficial to plot SNRM profiles and line speed. Such should provide evidence that there’s a fault somewhere.

No, since Message 18 I have been connected through my BT Business Hub5 which runs Openwrt. I have yet to rebuild my network to avoid the conflict caused by BT using one of the private IP ranges.
Is there a way to collect the SRNM Vs Line speed automatically, or do I have to manually record it and plot on a spreadsheet?
Edit: Reading the linked Kitz forum thread on the RouterStats package. I think I have Wine on one of my boxes.

I have not been able to get routerstats or routerstats-lite to work with my modem/routers. I have tried my BT Business Hub5 running OpenWRT, the Asus DSL-AC68U and the Plusnet Hub One (both running their respective manufacturer's firmware).
I cannot get past setting up noise margin and speed locations.
Both packages seem to start ok under Wine, Routerstats-lite states "But please note that RouterStats-Lite will only work with routers which have a separate popup login authentication dialogue box." Non of mine use this feature.
I am not sure what to try next to record the DSL statistics.

RouterStatsHub will work with the Hub One, make sure to follow the instructions in configuration information.

@Browni Would the OpenWRT firmware cause any problem? - Just asking, because I know nothing about it.

Hi,
You need Routerstatshub 5a for a Plusnet Hub One, it does work in wine.

I have successfully used RouterStatsHub with a Hub One which is why I mentioned it as it hadn't been mentioned before.

The xdsl stats http server url will be different to the original firmware url, when OpenWrt is installed.
Vwlowen may be willing to customise routerstats lite.

Thanks for your help.
I have now installed the Plusnet Hub One modem/router, and have RouterstatsHub 5 running on a tablet.
I suppose I need to keep the monitor running until after something interesting happens.
Regards,
Alistair

This morning my company computer absolutely refused to connect (via a VPN) through the Hub One, so so I replaced with the HH5 running OpenWRT.
The RouterstatsHub 5 log and chart images (recorded over the weekend) are attached.
Over the weekend the connection seems to have been laggy, with web sites slow to respond. Today the connection has been down a few times, including one that caused the HH5 to reboot.
The phone line is crackly, and the noise is louder when listening to the caller, or the quiet line preamble message.
The current summary shows:
Line Mode: G.992.5 (ADSL2+)

It does not help that there logs and plots are discontinuous, however the data does provide sufficient information to indicate that there is a probably line fault, as supported by your report of line noise. The SNRM is 'all over the place'.
You would best be served by pursuing this as a phone line (POTS) fault.

Sorry @Townman , I didn't think to check the settings on my netbook to try keeping the package running.
Should I pursue the phone line noise issue through the call centre on the user website, or can a Plusnet staff member pick it up from here?
I do not want to 'double post' and miss something.

For the last month the ADSL connection has been intermittently unreliable, but I haven't had the chance to report it or try changes.
The connection appeared to be changed from interleaved to fastrack about a week ago and has got worse again.
This morning has been particularly bad with frequent disconnects.
The quiet line reveals white noise, crackles, and strange machine generated tones. I tried the Plusnet phone troubleshooter and line test, which reported No Fault Found.
Attached are the BT Wholesale line test report, and an extract from the modem/router log and summary from earlier this morning.
Please help as we have two people working from home and a final year undergraduate trying to complete their course.
Regards,
Alistair
