How Long Do Modems Last? Should You Replace Your Modem?

It is difficult to say exactly how long do modems last, as there may be differences in usage and differences in quality among different types of modems.

But since it is an important part of the electronic hardware in your home, a good quality modem is very important for internet connection.

No modem lasts forever, but the modem needs to be replaced after a certain period; it is necessary to have a minimum idea about this.

How long do modems last? – Average lifespan

I said at the beginning that you couldn’t say exactly about the life span of a modem, but it is estimated that a modem can be used for 2 to 5 years or more even after regular use.

If you have a good quality modem, you can safely use it for more than five years, but you must pay attention to proper maintenance and care in this case. Moreover, the era is changing day by day, so our electronic devices need to change over time to stay upgraded.

If you replace the old modem, you will understand the advantages of the new modem, or you can compare your new one with the old one of your neighbors.

However, many times the modem does not work due to not updating properly, or many times due to IP-related complications that may not work. In that case, you must talk to your internet service provider; they will look into the problem.

However, things like slow internet or no net connection are usually the result of the modem not working, in which case your IPS will tell you about replacement.

But, my suggestion is that even if there is no problem with the modem, it needs to be changed after the warranty date has passed. Because the modem is used for a long time, the net speed gradually slows down.

In the new modem, you will get many more benefits such as high speed and stable net use. If your internet service providers do modem replacement directly, you must ask to provide a high-quality modem.

Signs your modem is going bad – When will the modem need to be replaced?

Many symptoms of a bad modem will make you realize that it is time to change your modem. I am highlighting the symptoms below.

Slow internet

Although internet speed is slow for various reasons, suppose your internet service provider says your internet plan supports speeds up to 100 Mbps.

But if you don’t get that amount of speed, then contact them. If they get everything right, then you have to understand it is your problem with the modem.

Connection error

Even if everything is fine if you see that your internet connection is disconnected almost all the time, but it comes back on immediately, or it doesn’t come for a long time, you must understand that this is the problem with the modem. So it would help if you replaced your modem to get better speed and stable net connection.

If it does not on

If you see that you can’t turn on your modem somehow, you need a new modem. However, you can try resetting; if it is on, it is good; otherwise, there is no way without change.

If there is no connection

If there is no net connection on the device even after the modem is on, you will have to change the modem.

High ping rate

Your modem will need to be changed to avoid this problem, especially if the ping rate increases while playing video games.

If you have to reset again and again, Sometimes after resetting the net comes, and if it continues like this non-stop, you must understand that you have to replace the modem.

  • Put it in a place where nothing is likely to get hurt or no chance of falling.
  • If your room is air-conditioned, make sure the modem does not get wet because too much moisture is harmful to the modem. But yes, it is better to keep it in a light cold place.
  • Do not put it in a place where the modem can get hot, such as in a place where direct sunlight falls.
  • It is better to avoid places where the temperature fluctuates.
  • Avoid harsh places where you can’t easily clean the modem or put in or put out any wires if you want.

So if you go to sleep at night or hang out outside, you must try to turn off the modem’s power; it will reduce the heat of the modem and get a little rest.

Keep in a dust-free place and keep clean

Try to keep your modem in a dust-free place, or it may be damaged if dirt gets inside. You can clean it occasionally, but keep in mind to unplug it before cleaning and, of course, do not try to clean it with water. You can use a clean thin cloth or wipes.
