My modem connection is slow
The computer’s modem uses K56flex™ technology/V.90. 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 this line.
