Radio frequencies can interrupt service through a modem from many different sources. Some of these interferences can be from a, Television, DVD Player, CD Player and Recorder, Speakers, Microwave Ovens or anything with Magnets and sometimes even Cell phones. In these cases, your modem may not work properly, or will work some of the time with intervals of no service. To keep this from happening with a wireless or regular modem, these steps should be taken.

To perform this test you will need: Internet service, Modem, Computer and all peripherals.

Move your modem at least 5 feet away from any other device that has an electrical current running through it. If it is not plugged in, you do not have to worry about moving your modem away from it. This includes speakers for your home theater or any that are connected to your computer.

Take off any device of any kind that is connected to your phone or DSL line that is connected to your modem for connecting to the Internet. If you have a filter, splitter or fax machine of any kind connected to the line, you need to disconnect it. Turn off all of phones that are connected to the phone lines. This does not include any cellular phones or phones that are not in use.

Reconnect all of your phones and other devices one at a time to see if your modem works with each of them connected. If there is one specific item that causes your modem lights to flicker, this should be permanently removed from the line to keep your connection active.

If you have instances where your modem works and then all of a sudden stops working, you should check to see if the wall it is closest to has a microwave on the other side. This can emit frequencies close to that of a modem, and will cause you to lose your connection even when the microwave is not in use. Cordless phones that run at 2.5 Ghz will also interfere if they are not filtered on the phone line that your modem is connected to. Filters can be purchased at any electronics store.
