❑ Check that the software you are using is compatible with the
notebook computer modem. (All preinstalled programs are

My modem connection is slow
Your notebook comes with a 56K/V.90-compatible modem. 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.
