How to Stop a Router From Overheating: Airflow and Placement Fixes

A hot router slows down, drops Wi-Fi and reboots itself. Give it open air, clean its vents and check the power adapter, then add a stand if it still runs hot.

Quick answer

To stop a router from overheating, give it open air: move it out of cabinets and off the top of the modem, leave a few inches clear on every side, and clean the dust from its vents. Check that the power adapter is not running hot too. If the router must stay in a warm spot, a cooling stand lifts it for airflow so heat does not build up. A router that keeps shutting off may have a heat problem, a bad adapter or aging hardware.

Free fix vs. permanent fix

Free fix · 15 minutes

Move it, clear it, dust it

  • Move the router to an open shelf, not a closed cabinet
  • Unstack it from the modem, cable box and game console
  • Unplug it and clear vent dust with a soft brush
  • Keep it out of direct sun and away from heating vents

How long it lasts: As long as the new spot stays cool and you wipe the vents a couple of times a year.

A router cooling stand

Some routers have nowhere good to go: a crowded media shelf, a warm closet or a desk corner next to the only cable jack. A stand raises the router so air can flow under it, and some add a small fan. It fixes the airflow problem when you cannot change the room.

What to get: Router cooling stand

How long it lasts: For as long as the router sits on it. It keeps air moving under and around the case.

Why it happens

1

Tight spots with no airflow

Most routers cool through vent slots with no fan. Inside a cabinet, behind a TV or between books, heat builds up and has nowhere to go.

2

Stacked on other warm gear

A router on top of a modem, cable box or game console absorbs their heat on top of its own.

3

Vents clogged with dust

A year or two of dust blocks the slots and works like a blanket over the circuit board.

4

Sun and room heat

A windowsill, a garage, an attic or a spot next to a heating vent can push the router past the temperature the maker designed it for.

5

A weak power adapter or aging hardware

A failing adapter can run hot and cause resets. Routers that are five or six years old also tend to run warmer and crash more.

Do these in order, starting with the simplest.

  1. Check how hot it really is

    Warm to the touch is normal. If you cannot rest a hand on the case for several seconds, or the power adapter is too hot to hold, act now. If you smell burning plastic or see melted or swollen plastic, unplug it and stop using it.

  2. Unplug it and clean the vents

    Tool used: Soft dry brush

    With the power off, brush the vent slots and the seams. If you use compressed air, give short bursts from a few inches away with the can held upright.

  3. Move it into open air

    Tool used: Router manual or label

    Put it on an open shelf or desk, ideally high and central, with 3 to 4 inches clear on each side. Do not stack it on the modem or put books on top. Many routers are made to sit flat or stand upright, so check which one yours is.

  4. Check the power adapter

    Use the adapter that came with the router. If you swapped it, match the volts and amps on the router label. A warm adapter is fine, and a hot, cracked or buzzing one needs replacing with the maker's part.

  5. Lift it if the spot cannot change

    Tool used: Router cooling stand

    If the only outlet and cable jack are in a warm nook, raise the router on a stand so air reaches the bottom vents, or mount it on the wall. Then watch it for a few days.

When free fixes aren't enough

If the router is in open air, the vents are clean and it still runs too hot to hold or keeps rebooting, the hardware may be wearing out. Many routers are replaced after about five years, and a new one often fixes the heat and the dropouts together. If it runs fine in open air but your only spot is a warm cabinet or crowded shelf, a stand is a cheap fix. Unplug it at once if you see melted plastic, a swollen case or sparks, or if the adapter smells of burning.

Router cooling stand

Fixes: heat building up in a tight or warm spot

Look for: An open frame so air flows under and around the router; A size and weight rating that suits your router; A stable base that will not tip, with gaps for cables; A quiet fan only if the spot is warm.

Who it's for
Someone who cannot move the router out of a media shelf or closet because the cable jack is there.
Honest downside
The router already runs cool in open air, since moving it costs nothing. Skip fan models if you will hear the fan in a quiet bedroom or office.

Fixes: a router with no open shelf space

Look for: A weight rating that holds your router and its cables; Vent slots left uncovered; Screws and wall anchors included; Support for the way your router should sit, flat or upright.

Who it's for
Anyone comfortable with a few screws whose shelf is full.
Honest downside
You cannot make holes in the wall, or your router is made to lie flat.

Router keeps turning off or restarting itself? Sort heat from other causes

  • Hot case, then a restart: heat. Move it and clean the vents.
  • Restarts when you touch the cord: a loose cord or a failing adapter.
  • Restarts at the same time each day: a scheduled reboot or a firmware setting.
  • Restarts when the lights flicker: a power problem. A different outlet, or a small battery backup, may help.

The best place for a router

Put it high and in the middle of the home, out in the open. Keep it away from microwaves, cordless phone bases and thick walls. A better spot cools the router and improves the signal at the same time.

What to skip

Decorative boxes and DIY fans

Boxes and covers made to hide the router trap heat unless they are open on the top and sides. Taping a loose fan to the case rarely helps and pulls in dust. Fix the airflow instead.

Frequently asked questions

Why does my router keep turning off?
Heat is one cause, since some routers shut down when too hot. Other common causes are a failing power adapter, a loose cord, a bad outlet or power strip, and aging hardware. Check the heat, reseat the cord, try another outlet and use the adapter that came with the router.
Why does my router keep restarting itself?
If the case is hot before a restart, heat is a likely cause. If it restarts at the same time each day or when many devices connect, look at firmware and the maker's support page. If restarts continue after you cool it, replace it.
How hot is too hot for a router?
Warm is normal. If you cannot comfortably rest a hand on it for several seconds, it is running too hot. Many manuals list a top operating temperature around 104°F (40°C), so check yours.
Is it OK to put a router in a cabinet?
Only if the cabinet is open or has large vents and the router has a few inches of space around it. A closed cabinet traps heat and weakens the Wi-Fi signal too.
