WiFi router – what is it and how to choose it correctly
Nowadays it is already difficult to meet a person who does not use a computer and does not have his home. Often people buy several computers, many also have laptops and smart phones – communicators.
A router or router is a network device that performs the function of forwarding data packets between network segments, in other words, the device helps to build a network between computers connected to it and, if possible, connect to the Internet. More modern routers can additionally perform a number of useful functions – for example, you can restrict access to potentially dangerous sites, enable a firewall, encrypt traffic, and so on.
What is a WiFi router?
The standard router, which is usually installed at home, is a small device, as a rule, a hardware unit, an antenna (with the WiFi function) are included, a power supply and a patch cord – patch cord. In the place where the router is installed, there must be a socket – do not forget about this when planning the network.
Using a router when building a home network will allow you to connect up to 4 computers via a cable and up to 5-10 devices via WiFi (however, you should not get carried away with a large number of connections – an inexpensive home device may simply not withstand such a load and will begin to freeze). If there is a USB port in the router, it is possible to connect a USB flash drive or hard drive and use the device as a print server, torrent client, file server. Some models boast support for 3G modems, which can often be very useful.
A home or office network through a router is a combination of all home computers in one local network with Internet access. Inexpensive routers, as a rule, have four ports that allow you to connect four network devices via cable to the router. It is not recommended to load a home router with a large number of devices, since the performance of the device can significantly decrease.
Another feature for some models is the presence of a USB port, which makes it possible to use connected flash drives or hard drives like file servers, and also if you have a 3g modem, you can connect it to your home router and distribute 3g Internet. As a rule, having a usb port allows you to use the router also as a print server. By connecting your printer to it, you can send documents from any computer connected to the network to print. Another important feature is the ability to work in VPN client mode, thanks to special firmware.
How to choose and buy a WiFi router
The best solution when organizing a home or small office network with Internet access is to buy and install a router that supports WiFi technology. This will avoid cluttering the room with numerous wires, however, it should be noted that for the deployment of a wireless network, computers must also have WiFi receivers and if they are already built into all modern laptop models, then you will have to buy them for stationary computers additionally – the price is about 500-700 rubles apiece. The same computers that are in close proximity to the router can be connected using a cable.
When choosing, it is worth paying attention to the following parameters:
At the moment, the price of a normal router for a home or small office is in the range from 1300 to 2000 rubles, you should not spend more on this device.
Support for IEEE 802.11g and IEEE 802.11n standards – will allow for the exchange of data over a wireless WiFi network at speeds up to 54 Mbps or up to 600 Mbps, respectively. In principle, IEEE 802.11g will be enough to solve typical problems.
The presence of a USB port and support for 3G – it is relevant where there is no opportunity to bring a dedicated channel from the provider.
Support for PPTP and / or L2TP – otherwise, it may not be possible to connect to the Internet from some providers, for example, Beeline works with these protocols.
