How to set up Wi-Fi

Today, more and more devices appear that can transfer data using wireless network technology Wi-Fi. This is laptops, and telephones and even TVs. It is not surprising that Wi-Fi-enabled routers are widely used, which make it possible to build a small local network from devices of various classes and different connection principles.

How to set up Wi-Fi

Usually, the router contains several LAN ports at the rear to connect network devices using a cable, a Wi-Fi antenna, and a WAN port that provides the connection of the router to the outside world. This can be connected to a cable from a local network, cable or telephone modem.

The principle of the “home” router is the creation of its own network with a single point of access to the network (usually it is the Internet) and the necessary routing of packets. You should carefully read the instructions for setting up your device. Usually, it is accessed through a web browser at a predefined intranet address, for example But sometimes you have to adjust the computer accordingly so that it can see the router.

In this case, for this, you must manually assign the address to the computer in the network in which the router by default works. Typically, the network address from the router computer will receive automatically, it is possible thanks to the built-in DHCP server. Its task is to issue network addresses in its internal network.

Typically, this service is devoted to a bookmark in the control panel of the router. Here you can configure the order of issuing addresses, their range, assign static (pre-defined for computers) addresses. Note that the ranges for local networks are predefined by standards, so do not assign an exotic range for the local network that can echo existing ones on the Internet.

It is better to leave the default settings or choose the traditional for LAN – In the event that the DHCP service is disabled, all computers on the network will need to configure the network and gateway settings manually, which is not recommended for inexperienced users, since it can only complicate the configuration.

In the “Network” or “Network” tab, the options for accessing the device to an external network are usually located. If the superior provider issues addresses automatically, then here you must leave the setting in automatic mode. If the device must have a static address or connect to a higher-level provider using a special VPN tunnel, then these settings need to be configured here, given the settings provided.

The Wireless tab or “Wireless Networks” is usually dedicated to setting up access to the network via Wi-Fi. Here you can select the name of the wireless network, the number of the radio channel over which the connection will be made. Note that some imported devices may not work on certain channels. Particular attention should be paid to the security settings of your router, “Security Settings”.

If the LAN port of home equipment hardly anyone connects unnoticed, then with the wireless equipment the situation is more complicated. So, any neighbor within a radius of ten meters can see the home wireless network and try to connect to it or even intercept the data. Therefore, you should carefully configure this section. Here you need to choose the type of data encryption and the key (password) to the network.

It is usually recommended to choose the most advanced algorithm – WPA2-PSK. Also in this section, it is proposed to restrict the access of wireless devices to their unique MAC addresses. So, knowing this parameter of the Wi-Fi adapter of your laptop and considering that no one else should enter the network, you can strengthen the network security by using this option. Disregard for security measures can lead to the fact that your traffic will be used with impunity by an outsider.That’s why you should pick up a unique key and not tell anyone to an outsider.

The router usually also offers the ability to collect statistics, create network routes, deny specific sites, set a password to access the device, back up the configuration, and so on. But in the simplest case, you just need to configure the router’s access to the Internet through the WAN port (often in automatic mode), configure the local network behind the router (just enable the DHCP server and set the range of the internal network) and configure the wireless Wi-Fi network (set the type encryption, the network name and the key to it).

On the same device with a wireless network adapter, it will be enough to search for networks and find its name there. At connection, it is probably necessary to specify type of enciphering (in modern adapters this parameter is selected automatically) and a key. This will be enough for wireless connection to the router. The device will receive the address in the created network, and then all network traffic will go through the router, which will forward it further to the Internet.

The user will not notice any difference in speed by connecting directly to the Internet or through a router. But this version of the connection will give much more advantages – now you can be on the web anywhere in the apartment without having to be attached to network cables.
