Re: Is there a free ISP for testing a modem

On Tue, 06 May 2008 06:10:50 -0500, just-me@xxxxxxxxxxx put finger to
keyboard and composed:

I have a dialup ISP and the connection recently got very slow.
Although I pay them a premium price for their service, their support
is terrible. I have run every test on my computer and modem and
everything seems fine. I had the phone company call me and say the
phone line seems ok, although they said that they can not be sure
without coming to my house and running tests, which would be costly
for me.

You could retrieve the modem's last call report using Unimodem
Diagnostics.

See http://www.modemsite.com/56k/diag.asp#ud for the configuration
procedure.

The following post contains a sample diagnostic report.

Look for retrains (bad) and renegotiations (not so bad). Also check
the Rx/Tx error counts.

Note that the initial connect speed may be significantly more
optimistic than the final receive carrier rate.

A simple test you could do on your line is to lift your phone
receiver, break dialtone by dialing any digit, and then listen for
total silence. Any hiss or "static" indicates a problem.

To enable the modem's speaker for the whole of your dialup session,
add L3M2 (or L2M2 or L1M2 for lower volume) to the Extra Settings in
your DUN connectoid's properties.

See http://www.modemsite.com/56k/connectoid.asp

You will then be able to hear what is going on. Short blips correspond
to rate renegotiations (eg 46667bps to 44000bps), whereas long 10-20
second negotiations similar to what you hear during the initial
connect phase represent retrains. Retrains are a sign that conditions
have become bad enough for the two modems to reassess the quality of
the phone line.
