Router Won't Turn On? Step-by-Step Fixes

No lights, no Wi-Fi, no internet, no streaming, no working from home. A dead router brings everything to a halt. Before you replace it, work through this list. About half of "dead" routers come back to life with the right steps.

1. Check the basics first

Before deep troubleshooting, confirm:

• Power cable is firmly plugged in both at the router and at the wall
• Wall outlet works (test with a lamp or phone charger)
• Power strip is switched on and the breaker isn't tripped
• Power adapter is the right one (mixing up power bricks between devices can fry a router)

If you have a surge protector, try plugging the router directly into the wall as a test. Some surge protectors fail silently after taking a hit.

2. Look at the power adapter (the most common dead component)

The power brick itself dies far more often than the router does. If you have access to another router's power brick that's the same voltage and current (check the label, usually 12V 1A or 12V 2A), try it. Or borrow one from a friend with a similar router.

Power adapters cost $10-15 to replace from the manufacturer if that's all that's wrong.

3. Try the 30-30-30 reset

This older trick still works on most consumer routers and is more thorough than a normal restart.

1. With the router on, press and hold the Reset button (often a tiny hole on the back, use a paperclip) for 30 seconds
2. While still holding the button, unplug the power cable. Keep holding for another 30 seconds.
3. While still holding, plug the power back in. Continue holding for 30 more seconds.
4. Release. Wait 5 full minutes.

Warning: This factory-resets the router, so you'll lose your Wi-Fi name, password, and any custom settings. You'll need to set it back up.

4. Check the LEDs and what they're telling you

Even a router that looks dead usually has at least one LED telling you something. Different brands use different lights, but generally:

• All lights off: No power. Check power adapter, cable, outlet.
• Only power light on: Router is on but not connecting. Internet (WAN) port may be dead, or modem isn't sending signal.
• Power and 2.4 GHz on, but 5 GHz off (or vice versa): One radio failed. Usually means the router needs replacing.
• Blinking red or amber: Internet connection problem. Call your ISP.
• Constantly cycling lights: Stuck in a boot loop. Power off for 5 minutes, try again. If it keeps cycling, the router is failing.

5. If you have a separate modem and router

It might actually be your modem, not your router. To test:

1. Unplug both
2. Plug in the modem first. Wait 2 full minutes.
3. Watch the modem's lights. They should go through a startup sequence and end with steady internet, power, and downstream/upstream lights.
4. If the modem looks healthy, plug the router back in.

If the modem never comes up healthy, the modem is the issue. Call your ISP.

6. Check for overheating

Touch the router. Is it hot? Routers in cabinets, on top of cable boxes, or stacked under things can overheat and shut themselves off. Once cool, they may come back.

• Move it to open air, on a shelf, away from other electronics
• Clean dust off the vents (canned air works)
• Don't put anything on top of it

When it's time to replace

If your router is more than 5 years old and none of the above works, it's almost certainly dead. Modern routers also bring real benefits:

• Wi-Fi 6 or 6E for much faster speeds
• Better range through walls
• Easier setup via mobile apps
• Automatic firmware updates for security

For a typical home, $100-200 buys a great router. For larger homes or homes with thick walls, a mesh system at $200-500 (Google Nest Wi-Fi, eero, TP-Link Deco) blankets everywhere with strong signal.
