A constant hiss on the line... TP-Link router solved problems, now they're back...
I have run all shielded cabling to the router, it still drops out every couple of hours...
In my case, the Downlink attenuation value fluctuated quite a bit for sometime in April and then it stabilised . I am not sure if the issues I had with the broadband speed were because of the attenuation, as subsequent monitoring of the data does not suggest attenuation values as seen in my HH6 has a direct bearing on the speed although I am speculating. I did collect data over a month when the broadband speed started fluctuating quite a bit and dropped to a level which I couldn't work with. Please see the attached graph. The data is collected every 2 minutes or so. Prior to 29th April, the speed was also fluctuating quite a bit as you can see in the initial part of the graph, and since then DLM did stabilise the line, and brought it back to my normal levels. Yes, took a while. But the Downlink Attenuation as you can see kept fluctuating quite a bit since then. It is now stable too. The Uplink attenuation did not seem to have fluctuated like this. As I said in my case the line is stable now with same firmware.
ps: the data in the graph is taken from router manually and painfully, no hacking /unlocking involved if anyone wonders
