Experts Warn: Outdated Wi-Fi Routers Slow Internet and Jeopardize Personal Security

After installing a Wi-Fi router at home, most users tend to use the router for years or until it breaks down. However, experts point out that like other electronic devices, Wi-Fi routers have a certain 'expiry date,' and old routers can compromise not only internet speed but also personal privacy.

Although Wi-Fi routers generally do not have a written expiration date, from the perspective of technological development and security, it is considered appropriate to replace the router every 4 to 5 years. According to organizations like Consumer Reports in the US, it is necessary to upgrade routers that are 3 to 5 years old.

When using an old router, users often face many problems, ranging from slow internet speed to poor signal reception. The biggest drawback of using an old router is the sluggish internet speed.

Most older routers are based on older standards such as 'Wi-Fi 4' or 'Wi-Fi 5.' In such cases, even if the user subscribes to an expensive 100 Mbps plan, the speed received is only 30-40 Mbps due to the router's limited capacity. In contrast, newer 'Wi-Fi 6' technology routers can deliver high-speed internet flow.

Compared to speed, the issue of security is even more serious. Manufacturers often stop providing software updates for routers that are many years old. In such a scenario, old routers lacking security shields become easy targets for hackers, leading to a high risk of personal details, passwords, and bank information being stolen. New routers, on the other hand, are comparatively safer as they come with modern security protocols (WPA3).

Similarly, the antennas and other internal components of the router weaken over time due to heat, causing the signal range to decrease. New routers feature modern technologies like 'Beamforming,' which focuses the signal directly towards the device, providing better range. Furthermore, nowadays, many devices like laptops, smart TVs, Alexa, and smart bulbs connect to the Wi-Fi in a home.

An old router cannot handle such a heavy load, but the 'MU-MIMO' technology in new routers can easily manage many devices simultaneously.
