I have been seeing the same thing but it is always from cities/TWP's that
are on the edge of civilization but not quite rural. I have one customer
who connects at 46-50k every time (Zoom 56k) but the connection will
eventually trickle down to 26.4 and then it just hangs up. I can sit on the
phone with him and watch the connection stutter, we see it stop then it
barfs a bunch of data across then stops etc... until it finally hangs up.
The client environment has been ruled out as the cause. The only fix that
worked was to add 3-4 commas after the phone number which knocked him down
to a consistent 33.6. Conversly, my urban 56k customers get 42-50k
connections that remain very stable.
So... you are not alone, I see the identical situation here.
