Check for line noise (scratchy, crackling, or 
popping sounds), which is a common problem 
that can cause the modem to connect at a slower 
rate, interrupt downloads, or even disconnect. 
You can also call your telephone service and have 
the telephone line checked for noise or low line 
levels.
Try another telephone line (either a different 
telephone number in your house or a telephone 
line at a different location). If you can connect 
on this line, call your telephone service.

such as line noise, telephone service provider 
equipment, or ISP limitations, may lower the speed 
even further.
