How To Resolve Cable Modem Disconnection

If your cable modem is having problems maintaining a constant connection to the Internet, it could be because the signal isn’t strong enough. If you have a splitter on the coaxial cable line (a y-shaped device used to connect two cables to one main cable line), this could be weakening the signal. Make sure that your cable modem has a dedicated coaxial line.

Also, you’ll want to recheck all the connections to and from your modem and make sure that every cord is attached snugly. And it never hurts to reset the modem and reboot your computer. But if this intermittent connection goes on too long, you’ll need to contact your service provider. If the cable signal in the room where you have your cable modem isn’t strong enough, your service provider can add a signal booster that will beef it up so it’s strong enough for high speed data transfer.
