Wi-Fi router and Wi-Fi: all you need to know about the wireless network

Wi-Fi router and Wi-Fi: The days when we used modems to connect to μέσω τηλεφώνου έχουν περάσει ανεπιστρεπτί. Το ασύρματο είναι πλέον το de facto πρότυπο για κάθε σύνδεση στο διαδίκτυο, αφού τα smartphones απορρίπτουν πλήρως τις ενσύρματες συνδέσεις.

So wherever we go we will find Wi-Fi networks. What do you know about particular networks and what do you need to know when you go to buy a Wi-Fi router for your home? Below you will find the answers you need.Wi-Fi router

What is Wi-Fi?

Η Wi-Fi Alliance announcement first launched the 1998 Wi-Fi. But it took about a decade to become a mainstream.

Despite popular belief, Wi-Fi does not stand for “wireless fidelity” rather than wireless fidelity. It is one signal for the specific technology based on the IEEE 802.11b standard used for wireless radio networking.

So all devices that are connected to a Wi-Fi network carry data with radio signals running through the network. Wi-Fi radio frequencies are broadcast at 2.4GHz or 5GHz. Networks in the 2.4GHz band have a maximum speed of 450Mbps, while the 5GHz networks reach 1300Mbps.

These are theoretical speeds, but they vary depending on the circumstances.

What does the Wi-Fi router do?

The Internet is piped into your home through a complex network of underground cables. (Those) Remember before the advent of Wi-Fi, the only option to connect to the internet was to use a cable. With Wi-Fi the connection that comes to our home with begins to circulate in the air. How is this possible? With a router, our well-known router.

The router or router is the central hub of your home network. Connects directly to your network cable either via a modem. All incoming and outgoing traffic is routed through the router.

Wi-Fi radio frequencies through the router are converted into radio waves that are used to transmit and receive from your connected devices. They often run on Linux-based operating systems. Most of them have a web page (with internal IP) to manage device settings and monitor your network activity.

Although different from each other, all routers have at least one CPU (Central Processing Unit). One or more microprocessors are responsible for running operating system commands, initialization, packet routing and network interface controls.

The routers belong to the 3 layer (layer 3) of the Open Systems Interconnection (OSI) model, Network Layer.

Each router uses one or more routing protocols. Based on these protocols, the router determines which servers or routers are the most appropriate at all times and routes packets of data to them.

Some well-known routing protocols are:
RIP, OSPF, BGP, IS-IS

What kind of Wi-Fi router do you need?

Depending on your ISP, you may need to purchase a device. Let's say many free devices that come with new internet connections are not the best. Almost all ISP providers in Greece currently use DSL (we also hope for fiber soon). There are routers and separate modems and even one-to-two router-modem devices. Most modern routers have built-in modems, so you only need one device.

There are hundreds of models you can choose from. Before you choose, however, it would be good to know what features of the device are important to you. Your requirements may be different if you plan to use Wi-Fi for online gaming or your work.
You can choose from big brand names of space, paying for quality and more security. For your home network, however, you will not need Cisco devices.

Secure and optimize a Wi-Fi network

Once you have your router, you need to set up your home network. This will vary depending on the device. But common to all devices, is finding the right location for your router. The location and direction of the antennas will ensure the best possible coverage. In case of low signal, Wi-Fi power supplies can be used to boost your local network.

Your router is usually the entry point to your home network. So should the first line of defense for your network security. Most routers have default usernames and ς s, which you should change immediately.

If your router supports it, you should change it frequency at 5GHz. This will minimize interference as other devices such as microwaves use the 2,4GHz frequency.

Do you need Wi-Fi?

Our digital life has now become mobile and Wi-Fi is very popular. A wireless connection allows you to access the Internet no matter where you are. Of course, a Wi-Fi network is useful for too many other than watching movies on the bed.
With a wireless network, you can create a media server in your home, play streaming , create networks for multiple devices (printers, computers, mobiles etc) for file sharing, and much more.
