Today, more and more devices appear that are able to transfer data using Wi-Fi wireless network technologies. It is not surprising that routers with Wi-Fi support have become widespread, which allow you to create a small local network at home from devices of different classes and different connection principles.

Typically, the router contains several LAN ports on the back to connect network devices using a cable, a Wi-Fi antenna, and a WAN port, which allows the router to communicate with the outside world. A cable from a local network, cable or telephone modem can be connected here.

The principle of operation of a "home" router is to create its own network with a single point of access to the network (usually the Internet) and the necessary packet routing. You should carefully read the instructions for setting up your device. It is usually accessed through a web browser at a predefined address on the internal network, for example But sometimes you have to properly configure the computer so that it can see the router.

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

Usually, this service is dedicated to a tab in the control panel of the router. Here you can configure the order of issuing addresses, their range, assign static (predefined for computers) addresses. Please note that the ranges for local networks are predefined by standards, so you should not assign exotic ranges for a local network that may overlap with those already existing on the Internet.

It is better to leave the default settings or choose the traditional local networks - If the DHCP service is disabled, all computers on the network will have to configure the network and gateway settings manually, which is not recommended for inexperienced users, as it can only complicate the configuration.

The “Network” or “Network” tab usually contains options for accessing the device to the external network. If the higher-level provider issues addresses automatically, then here too the setting should be left in automatic mode. If the device must have a static address or connect to an upstream provider using a special VPN tunnel, then these parameters must be configured here, taking into account the settings provided.

The “Wireless” or “Wireless Networks” tab is usually devoted 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 through which communication will be carried out. Please 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 hardly anyone will connect to the LAN port of home equipment imperceptibly, the situation with wireless equipment 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 data. Therefore, you should carefully configure this section. Here you need to select the type of data encryption and the key (password) to the network.

It is usually recommended to choose the most advanced algorithm - WPA2-PSK. This section also proposes to restrict access of wireless devices by their unique MAC addresses. So, knowing this parameter of the Wi-Fi adapter of your laptop and taking into account that no one should enter the network except for it, you can strengthen the security of the network by using this feature. Neglect of security measures can lead to the fact that a stranger will use your traffic with impunity. That is why you should choose a unique key and not share it with anyone else.

A router usually also offers the ability to collect statistics, create network routes, prohibit certain nodes, set a password to access the device, backup configuration, and so on. But in the simplest case, you just need to configure the router's access to the Internet via the WAN port (often in automatic mode), configure the local network behind the router (just turn on the DHCP server and set the range of the internal network) and configure the wireless Wi-Fi network (set the type encryption, network name and key).

On a device with a wireless network adapter, it will be enough to search for networks and find your name there. When connecting, you may need to specify the type of encryption (in modern adapters this parameter is selected automatically) and the key. This will be enough for a wireless connection to the router. The device will receive an address in the created network, and then all network traffic will go through the router, which will redirect it further to the Internet.

The user will not notice much difference in speed by connecting directly to the Internet or via a router. But this connection option will give much more advantages - now you can be on the Web anywhere in the apartment without being tied to network cables.
