Neither are compatible with my Netgear DGN150. Apparently I could use RouterStats-Lite with my Draytek VG2820n, but would it give me any metrics I don't already receive from the Draytek via syslog every five seconds? A typical log line gives me sync speeds, S:N ratio, and line attenuation e.g.:

Jan 10 03:04:23 vigor2820vn Vigor: ADSL_Status:[Mode=G.DMT States=SHOWTIME UpSpeed=608000 DownSpeed=3520000 SNR=12 Atten=47 ]

So I can already collect this data for analysis, but I'm not sure how that would help? Regardless of what I notice, isn't the noise on the line only fixable by BT/Orange engineers, who would always run their own diagnostics anyway rather than rely on the customer's personal analysis?

What he is after in one respect at least is the pattern of the noise variation and re-syncs, which RouterStats(Lite) graph very well as they keep going. DMT is useless for this as it stops at a disconnection.

If you can upload a graph of those from your logs that would be just as good.

Recently I've been using the DGN150 provided by Orange so that they can't complain about non-approved routers when they get me to run through their diagnostics. Unfortunately that router doesn't log useful metrics over syslog, only the precise time of the drop. I'll switch back to the Draytek and start collecting after they're done with their current investigations. But I've been keeping an eye on it, and generally every day falls into one of three categories:

1. no drops at all
2. drops all day long
3. drops only in the early morning, especially around 7am

Ultimately AFAICS from the OFCOM CoP, it should be the ISP's responsibility to figure out the problem and I shouldn't have to waste hours of my own time debugging it.

I do wonder if any of this could be related to the FTTC work that BT are supposedly finishing off right now in our area ...
