Hi,

You have your modem set to show computer to modem speed, which is always
115200, not the actual modem to modem connection speed. The actual speed
depends highly on the kind of telephone line you are using. I used to
connect with my 56k modem at full speed, and using the other 33.6k modem, I
got 33.6 connection all the time. Then I moved. Now I am lucky if I get 28.8
from my line, and lots of times it's just 26.4 or even slower. This
translates to about 2k/s. The line you have is more then ok for voice, but
for a high speed modem connection it is not. The telephone companies used to
save money by putting several customers on one line. As I said, for voice
that line sharing is ok, but modems do not like that. Check your modem
manual, and change the setting to show you the actual modem to modem
connection speed, and you will see the cause of your problem. The solution:
call phone company and ask them if they have any plans of upgrading the
lines, but unless there is a volcano eruption in the neighborhood... For
now, just suffer. Later you can consider SDL or some cable modem, when they
become more available and priced for normal people. Sorry...

Cheers
