1 noise spike in 45 minutes that did not cause a resync does not represent a problem from the view of the suppliers side of things...
I'm curious as to which service you are on now, that keeps flipping interleaving off/on? And how you are checking that it is doing this?
It's now done the same thing twice more in the last two hours and these times it did appear to re-sync. Download speed rapidly getting lower!
Was on ADSL2+ (G.992.5). I now appear to be back on G.992.1 (which I'm assuming is ADSL1). This has happened while I nipped out to the shops.
As to Interleaving. The application Routerstats appears to say whether it's on or off. This agrees with DMT. The FEC count also indicates this and Interleave depth was reporting as 1, which I also assumed was "off". The ISP also confirmed that when my line was initially switched to ADSL2+ that Interleaving was on, then on the 30th... it switched it off. They then requested it switch back on.
Confused I am.
