Q: Why my modem is not getting
A: There can be many reasons for this
problem. You can try and take following troubleshooting steps.
1. Make sure that your telephone line is properly plugged
into your modem. If this connection is loose then your modem
may not get dial tone.
2. There may be a problem on your telephone line or the telephone
cable may have gone faulty. In this case, you can verify by
connecting a regular telephone or connecting modem to another
3. A common problem is plugging your telephone line into
the wrong jack on your modem. Many modems have two jacks,
one for the telephone line and one for a telephone handset.
Make sure that you have hooked the telephone line in correct
4. Make sure that all other devices connecting to the telephone
line are properly connected. This problem may arise if some
other device like a telephone answering machine on the same
telephone line is not connected.
5. Make sure that you can get a dial tone on a telephone
handset connected to and through your modem when the modem
or computer (in case, you have an internal modem) is turned
6. Many voicemail systems use a "stutter" dial
tone or beeping when you pick up the phone to indicate that
you have voicemail waiting. These unexpected sounds can make
the modem think there is no dial tone.
7. In extreme case, your modem may not be designed for the
phone system in the country in which you are trying to use
Q: Why do I sometimes get abruptly
A: This is a common problem that most
dial up connection users face often. Here we discuss possible
1. If you have Call Waiting feature in your modem, the incoming
call "beep" may sometimes disconnect you. To avoid
this problem, you may be able to temporarily disable Call
Waiting when you make a data or fax call.
2. If your modem may receive some errors while transmitting
data. If your modem fails to correct the error then the uncorrected
transmission errors may make the transmitting remote site
may disconnect you.
To avoid this possibility it is better to have error correcting
connections. In this case, if the negotiation of error correction
fails then the modem will fail to connect. However, this will
allow you to configure your software to retry the connection
3. Disconnections may be caused by certain comm applications
when they produce DTR. By default most modems respond to a
drop of DTR by hanging up. With most modems you can work around
this problem by disabling DTR.
Q: Why do connections sometimes
seem to run slower and slower?
A: A lot of people using dial up connections
face this problem of modem getting “slower”. The
modem may start at good speed and then drop speed or in some
cases; it may run well for some time and then suddenly fall.
There are many different causes for this problem...
1. Your modem is dying. Over a period of time, the modem
may experience technical issues or give low performance because
it is getting old.
2. Sometimes it is observed that the modem may constantly
fall back to lower speeds gradually. There may be rise and
falls in the modem speed. However, in this case, the modem
speed falls constantly without ever being getting faster or
moving to higher speeds at anytime. Here, the line conditions
may would have permitted a higher speed (This may or may not
have been true. It can definitely be said only after conducting
tests with proper equipments.
3. Sometimes the modem does go back to high speed after dripping
to original speed. It will not go higher then that speed.
The modem sometimes takes the previous connection speed and
sometimes goes back to the original connection speed, but
it will not go higher then that.
In this cases, you may try Disconnecting and reconnecting
internet connection. However, this may not actually produce
result if the quality of the connection is poor. This it self
may be one more cause why you get slow connection...
This problem does depend on the connection as well. Therefore,
some dialup users do encounter it on some connections and
some other with better quality connection may never encounter
Another very rare case, that has been observed is that adjusting
the speaker volume control while accessing internet on your
dialup connection causes the modem to get slower!! In this
case, higher connection speeds may be possible if the volume
control is turned slower before getting connected the initial
negotiation or leave the volume as it is after getting connected.
But, remember, this is a rare case; it may not be very effective
in most of the cases.
There are some fixes that you can try…
1. If possible try a different modem and see if the problems
persist or not. IF yes then the issue is with the line and
if no, then your modem is problem.
2. Try to improve quality of your telephone line or the connection
to modem. Quality of wiring does contribute to speed of the
3. Try turning the volume control all the way down before
