Test your phone
- Remember that abnormal weather
conditions can affect how your modem performs,
particularly high winds or damp.
- Noise on the line is one of the
biggest causes of connection instability. To check the
quality of your signal, dial 17070, select the option
for a quiet line and listen carefully for any crackles.
The line should be free of any random noises.
- Call your phone company and tell
them that you are using a modem on your line and that
you want AGC (automatic gain control) turned OFF and the
gain increased. Make sure that you say there is nothing
wrong with your normal voice communications (if that is
the case), otherwise they will just do a normal line
- Disable call waiting on your
telephone line. For most phone companies this means
dialling dial #43# on your voice phone
- If you have two phone lines or
more in your house, you may find that they have been
installed using a DACS box, which effectively splits
your phone line into two, each of half the bandwidth.
This is fine for voice calls but completely ruins the
speed of an internet connection. If you have more than
one phone line, ask your phone company if they have used
a DACS box, and if they have, enquire about the
possibility of having two *full* phone lines, i.e. two
actual cables from your house to your exchange, instead
of a DACS box.
