What is a router? Here’s all you need to know

The internet is great, isn’t it? All the information you need is always just a few clicks away, and yet most of the time we fail to appreciate how good it is over the past few years. While we enjoy widely available Wi-Fi coverage in the home, have you ever wondered how data packets get to your browser when you request information? There are a lot of things that make this possible; one of them is a router. In this article, let’s take a look at what a router is and how exactly it works.

What is a router?

Router is a device that transmits data from the Internet to multiple devices in your home. Data is transferred from the router to the devices using radio waves, ranging from 2.4 GHz, 5 GHz and 6 GHz. If you would like to learn more about Wi-Fi frequencies, be sure to check out our “What is Wi-Fi?” »Article.

People often confuse Router and Modem when the two are two completely different things. You see, a computer can only understand digital signals, but your ISP’s signal is analog. A modem converts the analog signal to digital and sends it to your computer, and vice versa.

Using a modem, you can only connect to one device, while if you connect the modem to the router using an Ethernet cable, your router can start transmitting radio waves, which can then be transmitted. received by Wi-Fi enabled devices. If you want to know more about Modem, see our article on the same.

How to choose the best router?

One of the most important decisions after choosing an ISP is finding a good router. Most ISPs provide routers, and while they “work” they have their own set of flaws. For example, most routers still aren’t dual band these days, which must be a huge deal breaker.

2.4 GHz networks have a wider range, but the packet transmission rate will be significantly slower than that of a 5 GHz network. The former cover longer distances, while the latter cover shorter distances, but faster, therefore better speeds.

If you have a connection of 150MB / s or less, don’t have more than three devices at home, and all you do is browse the internet and stream 1080P content online, a router single band will do the job. However, if you have more devices and your job requires a super-fast internet connection, you should buy a dual-band router without hesitation. We always suggest buying a dual band router as it justifies the bills you pay your ISP by providing better speeds.

Do you own a dual band router? What is your internet speed? Are there any details we missed that you would like to mention? Let us know in the comments section below.
