The modem is the most critical piece of networking hardware in your home, because it provides a connection to the internet. If your modem ever stops working, you won’t be able to get online. So how often should you replace your modem to prevent a sudden catastrophe? The general rule of thumb is every few years, but it depends on a lot of different factors.
How often should you replace your router and why?
As with any other networking hardware or technology in general, there is a significant difference between basic and high-end modems. Low-end modems typically have a lifespan of two to three years, while high-end modems typically last more than five years. In general, you can expect a modem to last two to five years before it needs to be replaced due to failure or obsolescence.
Higher quality modems tend to use higher quality components, such as better capacitors that will last longer before they fail. Some modems are better designed than others for heat dissipation, which can also help them last longer. For example, a well-ventilated modem that is regularly cleaned and dusted inside will last much longer than a poorly ventilated modem that has never been cleaned or maintained in any way.
In addition to build quality, case and heatsink design, and the level of maintenance provided over the life of a modem, you should also consider features and capabilities. Even if a modem is still technically working, it’s often a good idea to upgrade if it doesn’t offer the fastest speeds possible, doesn’t have the latest wireless networking standards, or is missing essential features.
