V.90 and 56Flex problems

[Chris Ward]

I can get connected with my V.90, US Robotic Sportster at about 44k on the
Hoboken (I live there) and Hackensack Pops, and the same with my Hayes
Accura 56k (Kflex) modems, but they get a very low thoughput. I get much
better thoughput when I use the Hayes, but only when I put several (4-6)
commas after the phone number, which seems to disable the 56k technology and
I connect (usually) at 26k. (I put enough zeros on the Sportster and I get
2400 bps). I think there is some kind of thrashing going on. I use mostly
Windows NT 4.0 service pack 3, and I get the same problem, and the same
thing happens with Windows 98.

Any ideas?

Weird. If you get decent throughput with the Hayes at 28.8, then it
can't be the connection on the provider-side. But your throughput
declines when the connection speed improves by 50%??? I couldn't say
about the NT, but at least the Win98 thing sounds like it might be the
old 'Max MTU' problem striking again. I can't think of anything else
which affects throughput so dramatically, although it is more often
responsible for generally slow connections with Win95/98. There is an
explanation of the fix at:

HOWEVER, since this fix involves updating your registry settings, it is
a Very Good Idea (tm) to backup your Registry, as well as the root
directory, generally, before mucking around with this at all.
