This morning I woke to find my DSL modem reporting a speed of 1984/512. Reran the spectrum analysis tool at DSLreports. I shows a theoretical 35xx/818....wonder if I could've really gotten the 6.0/768 tier to at least get the much higher upsteam speed. It would've only been $5 more per month. (The tiers were 1.5/384, 3.0/512, 6.0/768 and the prices were $25/$30/$35).

I graph the SN margin/Line Attenuation along with up/down speed from the modem in cacti....so I see that my SN margin has dropped quite a bit, and Line Attenuation has gone up a little. So I see it started shifting gears around 5:20am.

Using the speed tool, I still can't get the reported speed. But, there is a proportional improvement. But, latency has dropped quite significantly. Better than cable now. Well under 100ms.

Don't know when the current DHCP leases expire, but I reconfigured DHCP to tell my Broadvoice VoIP service to use DSL as its gateway now. Wonder if there's anything else I want shift around....

Follow up:

Wonder if any more speed improvement is possible within the current tier or if I should see about pushing for the higher tier.

Here's the graphs of from cacti of what the modem is seeing:

In case you're interested, here's what the spectrum tool at DSLreports said on May 11th, 2008:

That's saying "Downstream Maxrate (Estimated): 3620" and "Upstream Maxrate (Estimated): 818".
