We can not walk customers thru fixing one. Fax machines and some answering machines using the same line that the modem does, have been known to cause disconnects. Disable any fax machines or answering machines and try connecting to the Internet without them. Simply turning them off may not have the desired effect. To play it safe, make sure they are unplugged and that your modem has a line straight from the wall.
Some modems just have a hard time staying connected on the Internet.
There are a number of types or specific models of modems that we've found that do not work with our service as well as others. Below are a list of modems that may have connection or disconnect problems. There will also be problems if you have a 28.8 VFC modem. VFC modems incapable of v.34, v.42 may not connect at speeds higher than 14.4 bps. Below is a list of modems that we've found excel under the worst possible conditions and will hold a connection when all else fails.
