How to Reset a Modem: Power Cycle, App Reset and Factory Reset

Resetting a modem forces it to reconnect and re-register with your provider, which fixes many connection problems. There are three levels, from gentle to drastic, and you should use them in order.

Method 1: power cycle the modem

1. Unplug the modem's power cord. If it has a backup battery, remove that too.

2. Wait 60 seconds.

3. Put the battery back in and plug the power cord in.

4. Wait two to five minutes until the online light is steady.

5. Restart your router only after the modem is back online.

Method 2: reset from your provider's app

Many providers let you restart or refresh a modem from their app or website. This asks the provider's system to re-provision the modem, which can fix problems a local power cycle cannot. It also works when you cannot reach the modem.

Method 3: factory reset with the reset button

1. Find the small recessed reset button.

2. Press and hold it with a paperclip for the time your model specifies.

3. Release it and wait for the modem to restart.

A factory reset returns the modem to its defaults. With a modem you own, it may need to be re-activated on your provider's network, so check with your provider first if you are unsure.

What the lights should do

After a reset, the lights cycle while the modem finds the network. The online light should become steady. If it blinks for more than ten minutes, check for an outage, tighten the coax cable and remove splitters.

If the modem will not reconnect

Confirm the modem is compatible with your provider and activated on your account, try another coax outlet and contact your provider with the steps you tried. See the lights guide for what each color means.

The bottom line

Power cycle first, use the app second and factory reset last. Give the modem time before you restart the router.
