The fastest way to fix your modem

Rebooting your modem means shutting it down completely and turning it back on. Most connection problems — slow speeds, dropped internet, pages that won't load — clear up after a reboot because it forces the modem to reconnect to your internet service provider's network. The whole process takes about five minutes.

The standard method is to unplug the power cable from the back of the modem, wait 30 seconds, and plug it back in. Some modems also have a power button on the front or back; if yours does, you can press that instead of unplugging. Either way works the same.

Key Takeaways

  • Unplug the modem's power cable, wait 30 seconds, then plug it back in to complete a full reboot.
  • A reboot clears temporary memory and forces the modem to reconnect to your provider's network, which fixes most connection problems.
  • The lights on your modem will go dark when you unplug it and return to normal after about two to three minutes.
  • If rebooting does not restore your connection after 10 minutes, check that all cables are firmly connected before contacting your provider.

Step-by-step reboot instructions

Step 1: Locate the power cable. Find where the power cable connects to the back of your modem. It is usually a thick black cord plugged into an outlet or power strip.

Step 2: Unplug and wait. Pull the power cable out of the modem. Set a timer for 30 seconds — this pause lets the modem's memory clear completely. Do not skip this step; plugging it back in when ready does not work as well.

Step 3: Plug back in and wait for lights. Reconnect the power cable to the modem. The lights will turn off, then come back on one by one over the next two to three minutes. Wait until the lights stop changing before you test your internet.

What the lights mean during a reboot

When you first unplug the modem, all lights go dark. This is normal. When you plug it back in, you will see lights turn on in a sequence — usually power first, then internet or connection lights, then activity lights. This sequence can take two to three minutes.

A solid light (not blinking) on the internet or connection indicator means the modem has reconnected to your provider. If the light stays red or keeps blinking after five minutes, the modem may not have reconnected properly. In that case, unplug it again, wait another 30 seconds, and plug it back in.

When to reboot instead of calling your provider

Reboot your modem first if you are experiencing slow internet, pages that load slowly, or a complete loss of connection. These problems often clear up after a reboot because they are usually caused by temporary glitches in the modem's connection, not problems with your service itself.

Do not reboot if you know your provider is doing maintenance in your area — they will usually send you a notice by email or text. If you have already called your provider and they told you to wait for a technician visit, rebooting will not help and may reset settings they need to see.

Checking cables before you reboot

Before you unplug the modem, take 30 seconds to check the cables. The coaxial cable (thick, threaded connector) should be firmly screwed into the port labeled "In" or "Cable In" on the back of the modem. The power cable should be fully inserted into both the modem and the outlet. Loose cables are the most common reason internet stops working.

If a cable is loose, push it in firmly until you feel it seat. Then wait a minute to see if your connection comes back. If it does, you do not need to reboot. If the connection is still down after checking the cables, proceed with the reboot.

What to do if rebooting does not work

If your internet is still down 10 minutes after the reboot completes, check the cables again — sometimes they work loose during the reboot process. If the cables are tight and the lights are back to normal but you still have no internet, contact your internet service provider. They can check whether there is an outage in your area or whether your account needs attention.

When you call, tell them you have already rebooted the modem and checked the cables. This saves time because they will not ask you to do those steps again. Have your account number ready, which is usually on your bill or printed on the modem itself.

Frequently Asked Questions

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

Wait at least 30 seconds. This gives the modem's memory time to clear completely. Waiting longer — up to a minute — does not hurt, but 30 seconds is the minimum that works reliably.

Will rebooting erase my saved passwords or settings?

No. A reboot only restarts the modem's connection to your provider. It does not change your Wi-Fi password, network name, or any settings you have configured. Your devices will still connect to the same network after the reboot.

Can I reboot my modem while I am using the internet?

You can, but your internet will go down when ready when you unplug it. Any downloads, video calls, or online work will stop. It is better to reboot when you are not actively using the internet, or to save your work first.

What if my modem has a reset button instead of a power button?

A reset button is different from a power button. Pressing reset will erase all your settings and return the modem to factory defaults, which is not what you want. Use the power cable method instead — unplug and wait 30 seconds.

How often should I reboot my modem?

You should only need to reboot when you have a connection problem. Rebooting regularly is not necessary and will not improve your speed if everything is working normally. Most people reboot a few times a year at most.
