It is almost impossible to imagine modern life without ubiquitous access to the Internet. The ability to connect to the network now is not only in public places, but in almost every home. It would be impossible without a special device - a router.
A router or router is a device that redirects data between a computer (tablet, phone) and a provider (service provider). Modern technologies allow data exchange in two ways: using a cable or Wi-Fi, a wireless network.
Communication between routers and Internet speed
Now there is a huge selection of routers. The market presents a variety of models: from budget to very expensive. The cost is influenced by design, brand awareness, materials, components and the level of their assembly. But A key influence on the operation of the device is the quality of the parts used.
A router is essentially a mini-computer with an embedded processor, RAM, and a network card (adapter) that determines the bandwidth of the router.
If the speed provided by the provider is 80 Mbit / s, but only 40 Mbit / s passes through the router, then the problem should be looked for in the used modem.
There are many factors due to which the router does not deliver the required speed. The most common ones are listed below.
Increase the speed of the Internet through the router
It is impossible to assert with complete confidence that the quality of data transmission depends on the modem only. There are quite a few technical reasons that influence this process, they are often interrelated. but You can solve the problem of slow Internet or significantly change the situation for the better by reconfiguring the router.
First you need to measure the current connection speed through the site //www.speedtest.net. After diagnosing each following problem and changing the operating parameters of the router, a new measurement should be taken and compared with the first result.
Important! To obtain accurate data at the time of testing, it is necessary to suspend programs that use traffic. It is advisable to carry out this test several times and analyze the figures obtained.
Speed Improvements
Free Wi-Fi channel
The best way to increase the bandwidth of a router is to start by searching for a free Wi-Fi network channel. If your computer detects a large number of Wi-Fi access points, you must bear in mind that all of them can be an obstacle to transmitting a good signal. therefore you need to find the least loaded channel and adjust the settings of the router.
WPA encryption specification
Another possible reason is the default old WPA encryption specification.
Important! It is considered outdated, unsafe to protect the wireless network and has an algorithm that significantly limits the speed.
Therefore, in the settings section of the router, it is necessary to update the encryption protocol on WPA2-PSK.
Adapter
It doesn't matter how powerful the router you use. is he will not be able to deliver the speed promised by the provider if an old-style Wi-Fi adapter is installed on the receiving computerthat can not support the standard 802.11n.
You need to update the adapter driver to the latest version, and then measure the speed of the Internet again.
802.11n operation mode
If the problem with the speed of traffic did not disappear after the upgrade, you need to check whether the above-mentioned 802.11n mode of operation is installed. This is a new version of the standard for all Wi-Fi networks, used since 2009.
Compatibility Mode
By default, automatic mode is always enabled in modems for maximum compatibility with any devices. To change it, go to the settings menu, select "Network mode". Then press 11n Only and be sure to apply these settings.
Power saving mode
Sometimes a low traffic rate can be observed on devices with activated power saving mode. It may affect the operation of the wireless adapter. therefore To check the system, you need to temporarily disable this mode..
Sleeping mode
The problem may also occur after the computer resumes from sleep mode. In this case usually helps reboot the device.
Distance
The greater the actual distance between the router and the computer, the worse the signal. therefore in a big house you need to use a high-power modem.
Number of connections
Finding out the reason for the slow Internet speed you need to take into account one nuance. It decreases depending on the number of units of the connected equipment. The router literally divides the signal between all clients, automatically reducing it due to the load created.
Low Internet speed is not always the result of poor provider performance. As a rule, the cause of the problem is the used router and its incorrect settings. When this is true, the problem is easy to diagnose and fix, having basic knowledge of how the system works.
