Chapter 3: Troubleshooting Your 56K modem does not connect at 56K Current FCC regulations restrict actual data transfer rates over public telephone lines to 53K. Other factors, such as line noise, telephone service provider equipment, or ISP limitations, may lower the speed even further. If your computer has a v.90 modem, the speed at which you can upload (send) data is limited to 33.6K. If your computer has a v.92 modem, the speed at which you can upload data is limited to 48K. Your ISP may not support 48K uploads. Your fax communications program only sends and receives faxes at 14,400 bps when you have a 56K modem • Current fax technology only supports a maximum send and receive rate of 14,400 bps. The modem is not recognized by your computer • Make sure that the line connected to the modem is working and plugged into the appropriate port on your computer. See your setup poster to make sure that the connections have been made correctly. • If the modem shares the telephone line with another device, make sure that the telephone line is not in use (for example, someone is on the telephone, or another modem is in use). • Use the modem cable that came with your computer. Some telephone cables do not meet cable standards and may cause problems with the connection. • Shut down and restart your computer. • Run Windows modem diagnostics. To run modem diagnostics: 1 Close all open programs. 2 Click Start, then click Control Panel. The Control Panel window opens. If your Control Panel is in Category View, click Printers and Other Hardware. 3 Click the Phone and Modem Options icon, then click the Modems tab. 36
