My modem connection is slow
Many factors influence modem connection speed, including telephone line noise or compatibility with telephone equipment (such
as fax machines or other modems). If you think your modem is not connecting properly to other PC-based modems, fax machines,
or your Internet Service Provider, check the following:
Have your phone company check that your phone line is free from any line noise.
If your problem is fax-related, check that there are no problems with the fax machine you are calling and that it is compatible
with fax modems.
If you are having a problem connecting with your Internet Service Provider, check that the ISP is not experiencing technical
problems.
If you have a second phone line available, try connecting the modem to that line.
