Have you ever been able to get faster (ie 48000, 52000, etc)
connections on this phone line with any other modem ??
If not, then this line may not support "56k" operation. Here is a site
with some info to consider:

I have an internal USR 56k v.92 FaxModem (5660c) which I just purchased a
week ago. Everytime I connect to my ISP (Earthlink) my connect speed is
*always* @ 24000bps. I just had the phone line fixed for line noise a few
weeks ago. I downloaded the latest drivers from the USR site. I put in
various init strings (taken from suggestions for other posts here from users
with similar problems) to no avail. I even tried calling a non-local access
# with the same connect speed. When I download a file from the Web, my d/l
speed starts out at 7k/sec but diminishes to a steady 2.7k/sec. It's like
the modem is capped to download at 2.7k/sec with a capped 24000 connect. As
a test, I connected a 486 running win95 with an ActionTec v90 modem (with
out of date drivers) using the same ISP and it connected at 26400 bps. What
gives? Any help would greatly be appreciated.
Here's the modem log file for the USR modem (sorry if it's too long; I
don't know which parts to snip out):

When I used the ActionTec v90 modem it never connected above 26400 bps.
The website you provided was very helpful. I found out that I have a 'soft'
modem and unfortunately that my phone line doesn't support a 56K connect.
Thanks for your help!
p.s. i accidentally replied directly to your email instead of replying to

the at y11 command doesn't work. It just says ERROR. I don't know what those

Your modem appears to use a Conexant chipset, not USR. AFAIK, the only
diagnostic commands that would be applicable are AT&V1, AT&V2, and
AT#UD. AT&V1 gives you an abbreviated report.
If you edit your registry as described at modemsite.com, then the #UD
data will be automatically appended to your modemlog. Otherwise you
can access it via HyperTerminal and analyse it using Stanislav
Mekhanoshin's utilities.
You wrote previously that "when I download a file from the Web, my d/l
speed starts out at 7k/sec but diminishes to a steady 2.7k/sec". For
an incompressible file such as a ZIP, this would be normal behaviour,
assuming you are relying on your browser for this information. This is
because your browser gives you a rolling average. If you are
downloading a compressible file when this happens, then you *may* have
a problem. One way to verify this is by checking your #UD or &V2
reports for max/min Tx/Rx speeds and Tx/Rx errors.
