Back to top My computer disconnects from the Internet at random times soon after I connect. This problem is commonly caused by an analog phone line. You may not notice it on the telephone with someone, but the computer is very sensitive to any modulation in the line signal. There are some steps to prevent this from happening. This is recommended only if you are have problems maintaining a connection to the Internet for an extended period of time.
Dropped connections can occur when there is a sharp decrease in line quality during a call.
V.34 modems will switch to rates as low as 4800 bps to compensate for these changes. If the loss of quality is extremely severe, they will drop the connection. First determine if the disconnects are random, occurring at regular intervals, or during specific operations. Time Out You may disconnect you if there is no activity for 15 or 20 minutes. The length of time is different depending on the your settings.
