Troubleshooting
Why is my modem connection slow?
Your computer is equipped with a V.92/V.90 compatible modem. Many factors may 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 ISP, do any of the following:
❑ Ask your telephone company to verify your telephone line is free of any line noise.
❑ If your problem is fax-related, make sure 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 ISP, make sure the ISP is not experiencing technical problems.
❑ If you have a second telephone line, try connecting the modem to that line.
