To reset, send the command AT&F (factory defaults) via terminal software. Alternatively, power off the modem, remove the power cord, wait 30 seconds, and reconnect.
Why doesn't my modem connect at 56K?
Factors include line noise, distance from the central office, and compatibility with the ISP modem. Also, FCC regulations limit maximum transmit power, so actual speeds may be lower.
