How Often Should You Replace Your Modem?

Is your modem broken? Is it just old but still functional? Thinking about buying a new one? You’ve come to the right place! In this article, we will list and analyze the most common reasons to replace the modem, give you some tips on how to prolong your modem’s lifespan, and finally tell you how often you should replace your modem. 

How Often Should You Replace Your Modem

What is a Modem?

The modem is part of the network hardware, which physically resembles a small box. Its task is to connect your devices to the Internet, using cables. To use WiFi in your home, you must add a router to your modem. This will enable wireless use of the Internet (some devices are a combination of router and modem – they are called gateways).

We’re sure you wouldn’t want to get into a situation where your modem stops working because in today’s modern times, functioning without the internet is hard to imagine. That’s why you need to know when is the right time to replace your modem with a new one, and it’s also very important to know what to do when it’s not working properly.

Modem Lifespan

When talking about the lifespan of the modem, it is impossible to give a completely correct answer, because it depends on several factors. Just like with other technology, modem lifetime is not the same for all models. Modems that are cheaper have a shorter lifespan, while those more modern, more expensive (higher quality) last longer. The most modern modem manufacturers use higher-quality parts for their production, which certainly affects the longevity and prolongs the lifespan.

The average modem lifespan is 2 to 5 years (apart from quality, it is influenced by many other factors).

Some modems can last for more than a decade if handled properly, but you have to keep in mind that even though they work, modems of that age are very likely outdated in terms of functionality and features. 

Tips for Longer Modem Life

In addition to the brand, the quality of the parts, etc., a very important factor that affects the duration of the modem is the way of use. Here are two very simple but important tips for proper modem use:

Use a Surge Protector

One of the most important things when talking about modem lifespan is the use of surge protectors. It aims to limit the amount of voltage circulating to the modem. It works on the following principle: if the voltage increases more than it should, it blocks that voltage. This way, your modem is safe from ‘’frying’’.

The Right Place for a Modem

  • Place the modem somewhere where you will not accidentally hit or knock it down. (Some modems are more durable than others, but that’s still not a reason to be careless).
  • Avoid places where there is moisture or where it can get wet easily. Placing it next to a kitchen sink is not a good idea.
  • While it is working, the modem releases heat, so there should be space between it and other objects. Heat buildup could cause some serious damage. 
  • The place where the temperature constantly varies is also not a desirable place for the router.
  • We recommend that the modem be located in an easily accessible place so that it is always at hand if needed.

Signs That Your Modem is Not Working Properly

If your modem is defective, you will best recognize it by the following signs:

  • You must reset the modem very often for the connection to work properly.
  • Frequent interruption of the internet connection.
  • Your modem is noisy at work, strange sounds like buzzing are heard.
  • Slow internet operation.
  • The lights on the modem are off.
  • It is impossible to establish an internet connection.
  • Inability to turn on the modem.

In addition to all these signs indicating that there’s a problem with your modem, do not be surprised if your modem stops working without any previous signs. This situation occurs if some of the most important parts break down.

What to do Before Replacing the Modem

In this, not at all pleasant situation when the failure leaves you without a modem and internet, the best solution is to contact your provider or to consider buying a new one. However, before that, it is useful to know that some actions may fix your modem. Try the following things:

  • Very simple operation, and very useful when you have problems with the modem – first turn it off the modem, wait a minute, and then turn it on again. In other words – reboot your modem. 
  • Check the plugs. There’s a chance that some of them are not properly connected.
  • Be sure to test the operation of your modem on several devices. If it works on some devices but one of them cannot be connected, then the problem is in that device, not the modem.
  • Change the socket where the modem was plugged in.
  • You can also do a factory reset. Locate the reset button on the back of the router (It is usually tucked into the hole, so use a paper clip or similar object to press it). Press and hold for at least 10 seconds. Note that this procedure will reset all the settings to factory defaults, so you will probably need the help of a provider when reconfiguring.

If none of these procedures make your modem work again, then it is definitely time to replace your modem.

How Often Should You Replace Your Modem?

Several factors could indicate that it is the right time to replace a modem. Some of the most common factors are:

  • Some new features have appeared that the current modem does not support, and these features are very important to you.
  • You want your internet to be faster and better.
  • The state-of-the-art network standards provided by your provider are not available on your current modem.
  • Your Internet Service Provider (ISP) supports new network standards that your modem does not support – here we can mention the DOCSIS standard which is replaced by a new one every few years (4-7). If you want the fastest and highest quality connection that will function under the latest DOCSIS standard, then a replacement period of 4-7 years is recommended.

Important Tips When Buying a New Modem

When buying a new modem, do not make a decision about the modem too quickly. Before buying, ask which model is supported by your ISP. It is best to check directly with the ISP which models are compatible.

We recommend that you change your modem at least once every 2-3 years. That way, there is a good chance that your modem will not break down and leave you without an internet connection.

On various forums, check how satisfied the users are with the model you want to buy.


Periodic modem replacement is of great importance. Even in a situation where the modem works normally and is not broken, there’s a good chance that, after a few years, it will not be able to keep up with the latest internet technologies and therefore will not deliver the highest available speeds.

That is why we recommend that you regularly follow the latest news about internet technology and improvements related to networking hardware and that you replace the modem every 2 – 3 years. That way, you will always get the most out of your modem.
