Router Keeps Dropping Wi-Fi? How to Fix It Step by Step at Home

Your Wi-Fi works, then it doesn't. Video calls freeze, the TV starts buffering, and your phone quietly switches to cellular. A minute later it's back like nothing happened.

By the end of this guide, you'll know whether the problem is your router, your internet provider, or one device, and you'll have fixed the most common causes yourself.

The short answer

Unplug both your modem and router for a full minute, then plug in the modem first and the router second. If the drops come back, check whether the modem's internet light goes out when the Wi-Fi drops. If it does, call your provider. If it doesn't, the router is the problem, and a channel change, better placement, or a firmware update usually sorts it out.

Before you start

• What you need: access to your modem and router, plus the router's app or admin password (often printed on a sticker on the router).
• How long: 10 minutes for the basics, up to an hour if you work through everything.
• Your files are safe. None of these steps touch your data. Write down your Wi-Fi name and password before changing any settings, just in case.

Step 1: Restart the modem and router the right way

The modem is the box that brings internet in from the wall. The router makes the Wi-Fi. Sometimes they're one box.

1. Unplug the power from both.
2. Wait a full 60 seconds. This lets them clear out memory that gets cluttered after weeks of running.
3. Plug the modem back in first and wait until its lights settle, usually 2 to 5 minutes.
4. Plug the router in and give it another couple of minutes.

If it worked, your devices reconnect on their own and stay connected. If you have one combined box, just unplug it, wait, and plug it back in.

Step 2: Read the modem lights

Those little lights tell you a lot. Labels vary by brand, but look for ones marked Power, Online or Internet, and sometimes DS/US (downstream/upstream, meaning data coming in and going out).

1. Watch the modem the next time your Wi-Fi drops.
2. Check the Online or Internet light.
   • Solid: the modem has a good connection. The problem is likely your router or Wi-Fi signal. Keep going.
   • Blinking, off, or red/orange: the modem lost its connection to your provider. That's on their end or in the wiring.
3. Check whether a computer plugged in with an Ethernet cable also loses internet. If wired and wireless drop together, it's almost always the provider.

On Fios, you may have a separate box called an ONT on a wall or in a closet. If its lights look off or alarmed, that points to the provider too.

Step 3: Rule out a single device

If only one phone or laptop keeps dropping, have it forget the network and rejoin. This clears out stale connection settings.

iPhone

1. Go to Settings → Wi-Fi.
2. Tap the (i) next to your network.
3. Tap Forget This Network, then rejoin and enter the password.

Android

1. Samsung: Settings → Connections → Wi-Fi, tap the gear next to your network, then Forget.
2. Pixel: Settings → Network & internet → Internet, tap the gear next to your network, then Forget.
3. Tap the network again and enter the password.

Windows 11

1. Go to Settings → Network & internet → Wi-Fi → Manage known networks.
2. Click Forget next to your network.
3. Click the Wi-Fi icon in the taskbar and reconnect.

Mac

1. Open System Settings → Wi-Fi.
2. Click the … button next to your network and choose Forget This Network.
3. Rejoin from the Wi-Fi menu.

Step 4: Move the router somewhere better

Wi-Fi hates walls, metal, water, and being stuffed in cabinets.

1. Get the router out of closets, off the floor, and away from the microwave and fish tank.
2. Put it up high and as central as you can.
3. Give it breathing room. A router that runs hot can freeze or reboot on its own.

Step 5: Change the Wi-Fi channel

In a building full of apartments, dozens of routers can be fighting over the same airwaves. Switching channels moves you to a quieter lane.

1. Open your router's app, or type its address into a browser. It's often 192.168.1.1 or 192.168.0.1, and the sticker on the router usually lists it.
2. Log in and find Wireless or Wi-Fi settings (sometimes under Advanced).
3. For the 2.4 GHz band, choose channel 1, 6, or 11. Those three don't overlap with each other.
4. For 5 GHz, try Auto, or pick a different channel than the current one.
5. Save and wait a minute for devices to reconnect.

Try one channel for a day before switching again so you can actually tell if it helped.

Step 6: Update the router's firmware

Firmware is the router's built-in software. Updates often fix bugs that cause random drops.

1. In the router app or admin page, look for Firmware Update, Router Update, or something under Administration or System.
2. Tap Check for updates and install anything available.
3. Don't unplug the router during the update. It will restart on its own when it's done.

Routers rented from your provider usually update themselves, so you can skip this if that's what you have.

Still not working? Try these

• Call your provider if the modem's internet light blinks during drops, or wired devices drop too. Ask them to check your line signal and look for outages in your area. Many problems are fixed by a new modem or a technician visit, at no cost to you.
• Split the bands. If your router combines 2.4 and 5 GHz under one name, some devices bounce between them. Giving each band its own name in settings can stop the hopping.
• Check every cable. Make sure the coax or Ethernet cables are snug and not kinked or chewed.
• Replace the router if it's several years old, gets hot, still drops after all of the above, or doesn't support Wi-Fi 6 or newer. For larger homes or multiple floors, a mesh system (several units working together) is usually a better buy than one big router.

Keep it from happening again

• Turn on automatic firmware updates in the router's settings if it has the option.
• Keep it cool and visible. Out of cabinets, off the radiator, up high.
• Plug the modem and router into a battery backup. Brief power dips can knock them offline without you noticing. Our UPS guide explains how to pick one.
• Schedule a weekly restart if your router supports it. It's an easy way to keep things fresh.
