A modem reset clears its memory and restarts its connection to your internet service provider

A reset wipes the modem's settings and forces it to reconnect from scratch. This is different from a straightforward restart (turning it off and back on), which just reboots the device without erasing anything. A reset solves problems like no internet connection, extremely slow speeds, or a modem that stops responding to commands. Most modems take 5 to 10 minutes to fully reconnect after a reset.

There are two types of reset: a soft reset (restart) and a hard reset (factory reset). A soft reset is what you should try first—it fixes most problems and keeps your settings intact. A hard reset erases everything and returns the modem to factory defaults, which means you may need to reconfigure it with your ISP afterward.

Key Takeaways

  • A soft reset (power cycle) fixes most modem problems and takes 2 to 3 minutes; unplug the modem, wait 30 seconds, and plug it back in.
  • A hard reset erases all settings and returns the modem to factory defaults; use it only if a soft reset does not work.
  • After a reset, wait 5 to 10 minutes for the modem to reconnect and show a solid internet light before testing your connection.
  • If your modem still does not work after a hard reset, contact your ISP—they may need to re-register the device on their network.

How to do a soft reset (power cycle)

A soft reset is the safest first step and fixes the majority of modem problems. Unplug the power cable from the back of the modem, wait at least 30 seconds (this clears the device's memory), then plug it back in. The modem will restart and begin reconnecting to your ISP's network.

While the modem restarts, you will see lights on the front blinking in a pattern. This is normal. Wait until the internet light (usually labeled "Internet," "Online," or "WAN") turns solid green or blue. This typically takes 3 to 5 minutes. Once that light is solid, your connection is restored and you can test your internet.

If the internet light does not turn solid after 10 minutes, or if you still have no connection, move on to a hard reset. But first, make sure the power cable is firmly seated in both the modem and the wall outlet.

How to do a hard reset

A hard reset erases all settings and returns the modem to the state it was in when it left the factory. Most modems have a small reset button (often recessed) on the back or bottom. You will need a straightened paperclip or a pen to press it, since the button is deliberately hard to reach by accident.

With the modem powered on, press and hold the reset button for 10 to 15 seconds. The lights on the front will go dark, then begin blinking again as the modem restarts. This process takes 5 to 10 minutes. Once the internet light turns solid, the hard reset is complete.

After a hard reset, your modem may need to be reconfigured. Some ISPs automatically re-register the modem on their network within a few minutes. Others require you to call and confirm the reset, or to log into the modem's web interface and re-enter your account information. Check your ISP's website or call their support line to find out what step comes next.

What the lights mean during a reset

The lights on your modem tell you what is happening. During a reset, you will typically see the power light turn off, then come back on. The internet or online light will blink as the modem searches for a connection. This blinking can last several minutes and is not a problem.

Once the internet light turns solid (usually green or blue), the modem has successfully connected. If the light stays red or off after 10 minutes, the modem is not connecting to your ISP. This can mean the cable line is disconnected, your account is not active, or the modem needs to be re-registered with your ISP.

When to call your ISP instead of resetting

If a soft reset does not fix the problem, and a hard reset still leaves you without internet, the issue is likely not with the modem itself. Your ISP may need to re-register the modem on their network, check the cable line for damage, or verify that your account is active.

Also call your ISP if you see a red light labeled "Online," "Internet," or "WAN" that does not turn green after a reset, or if the modem keeps losing connection every few hours even after a reset. These are signs of a problem on the ISP's side or with the physical cable line.

Resetting a modem with a battery backup

Some modems have a built-in battery that keeps them running during a power outage. If yours has one, unplugging the power cable alone may not fully reset it. You will need to hold down the reset button while the modem is unplugged, or unplug it and then press the reset button after waiting 30 seconds.

Check your modem's manual or the manufacturer's website to confirm whether yours has a battery. If it does, the manual will explain the correct reset procedure. When in doubt, pressing the reset button while the modem is unplugged is the safest approach.

Frequently Asked Questions

Will a reset erase my saved passwords or Wi-Fi network name?

A soft reset (power cycle) does not erase anything. A hard reset erases all settings, including your Wi-Fi network name, password, and any custom configurations. After a hard reset, you will need to set up your Wi-Fi network again and may need to reconfigure your modem with your ISP.

How long should I wait before plugging the modem back in?

Wait at least 30 seconds. This gives the modem time to fully discharge and clear its memory. Waiting longer (up to a minute) does not hurt and can sometimes help if the modem is very stuck.

Can I reset my modem while someone is using the internet?

You can, but they will lose their connection when ready. The modem will be offline for 5 to 10 minutes while it restarts. It is best to reset during a time when no one is using the internet, or to warn people first.

What if the reset button is stuck or does not work?

If the reset button does not respond after pressing it firmly for 15 seconds, try using a different tool (a straightened paperclip works better than a pen for some buttons). If it still does not work, a soft reset (unplugging and replugging) is your next option. If neither works, contact your ISP or the modem manufacturer.

Do I need to reset my modem if I am getting a new one?

No. straightforward unplug the old modem and plug in the new one. Your ISP will handle the registration on their end. A reset is only needed when your current modem is not working properly.
