Why is My Router Hot? (How to Avoid Overheating?)

by stacy

Is it normal for routers to get too hot? It is possible for electronic devices such as routers and modems to heat up due to increased internet usage. The result can be catastrophic: a drop in Wi Fi speed, loss or malfunction of routers, modem malfunction, and worse, other hardware malfunction.

The router uses less power than other electronic devices and computers. It won’t get too hot. It can heat up if the router is placed in an enclosed space that doesn’t have cooling fans or airflow. This article will discuss why routers heat up and how to prevent it. Let’s get started.

Your Router is Hot

Routers were designed to run for extended periods of time and not become too hot. They can overheat for a variety reasons.

Blockage of Air Vents

Although routers don’t usually come with cooling fans or air vents, they do have them on the sides. These vents allow hot, circulating air to escape from the internal parts. These vents also allow cool outside air to flow through, keeping the internal components cool.

Placing objects near or around the router can block airflow. It is a bad idea for the router to be placed in restricted areas such as cabinets, drawers, boxes, or any other area that restricts airflow. This will limit airflow and heat the router.

Don't block air vents

There is an easy solution to open spaces in your home. The router can be placed in the right place. If this is not possible, you can place the router on a higher ground such as a shelf. Mount the router on a wall, and attach it to an unobstructed surface. It is a good idea to keep the router at least five feet from other objects. This arrangement should allow your router to breathe and prevent overheating.

Hot Surrounding

You may find that the space in which you place the router is too hot if you live in a hot area. The router’s temperature will rise because there isn’t any cool air.

It is also not advisable to place the router too close or near electronic devices such as a TV or purifier. The router will heat up the air and make it inoperable.

This problem can be solved by installing a cooling fan. Cooling fans can produce air movement and circulation, which is much more effective than static even though the air temperature is high. Cooling fans are very affordable and can be installed quickly without the assistance of a technician. The cooling fans can be used to solve the heating issue of your router.

Bad Router Design

There are many router manufacturers. There are many other models. Bad design can lead to poor buying decisions. The manufacturer could have used a chip that produces heat in the circuitry. A second design error is not having adequate vents for airflow on router sides. Bad designs can lead to heating problems.

You can avoid purchasing a poor router by reading reviews online from other buyers. This will help you to find out if there have been any complaints about heating issues with the particular router model. These reviews can help you find a reliable router, with no problems in particular cases of overheating.

Faulty Power Supply Unit

A faulty power supply unit (or PSU) can cause routers to heat up. The router can get hot if you use a non-standard PSU, which gives more than the 12V. You can correct this by replacing the PSU or checking it.

Too many connected devices simultaneously

Many people work from home these days. Many routers and gateways have the ability to handle multiple devices. It is not surprising that every family has multiple connected devices.

There is a limit to how many devices a router can connect simultaneously. Your router could experience heat if it connects more than the limit.

You can reduce the number of devices connected to your router if it overheats.

Sometimes family members will connect all their devices and keep them connected, even when they are not using them. It’s a good idea to disconnect these devices for a while so that you can reconnect them when needed. If you have the money, you can buy a larger router. This will enable you to connect multiple devices at once.

What happens if your Router becomes too hot?

Your router can get a little too hot from continuous operation. This is perfectly normal. If the router heats up, it can cause damage to your internet connection or hardware malfunction.

Internet Disconnection

Overheating can cause internet speed drops. Unlucky users may lose their connection. Before you try to reconnect, turn off your router and let it cool down for a while. After the router cools, your internet connection speed will return to normal. It’s likely that your internet connection drops if the router heats up again after a while.

Hardware Failure

Overheating can cause hardware failures, just like other electronic devices and computers. When the temperature rises above a certain point, the router’s internal components will start to wear out. The router will automatically restart if the heat limit is exceeded. This saves internet parts. The router will stop working eventually unless you do something.


You won’t need to worry about your router becoming too hot if you have read this article. The most common reasons for router heat have been listed along with the solutions. It is possible to leave the router on for as long as there is adequate ventilation. This makes it very easy to use.

It is important to remember that routers should work as long as the temperature doesn’t exceed 100 degrees Celcius. The router will stop working if it reaches 100 degrees Celcius. It is best to keep the router at 70-80 degrees Celcius. This is the router temperature and not the ambient temperature. The ideal ambient temperature is between 70 and 75 degrees F.

Before you go, one more thing: If you aren’t going to be using your router for a while, make sure to turn it off.
