A question from the user, I have an Internet rate of 100 Mbps, and the download speed of torrents on a laptop on Wi-Fi does not exceed 2-2.5 MB/s. Tried to connect the same laptop to the router network cable – the download speed increased to 8-9 MB/s.
Tell me, is it possible to achieve the same speed on Wi-Fi, and how to Improving the network’s speed? And it turns out that for me, the speed of the provider is not important.
Most likely, the router is too “weak” and can not physically provide a faster mode of operation. To begin with, it would be nice to clarify the model and characteristics of the router and the Wi-Fi adapter in the laptop …
Anyway, below I’ll show you how to check it and several other causes of this problem.

What you can do to increase Wi-Fi speeds
STEP 1: Check the signal quality and power of the router transmitter
And so, to begin with, I recommend paying attention to the level of the Wi-Fi signal network. In general, it is not necessary to even go into any router settings. Just look at the network icon: if the signal level is all right, you will see all the strips “drenched” (as in the example below).
In general, the level of the Wi-Fi signal is greatly influenced by the distance between devices, such as a laptop and router. The further they are between each other – the lower the speed of exchange.
In addition, if there is a wall between the router and the laptop (mirror, door, etc.), the signal’s quality (and the speed of the information transmitted) can be significantly reduced. When diagnosing and finding the reasons for slow Wi-Fi – try to put your laptop at least 2-3 meters from the router for a while.
Well, I can’t help but note one point – most modern routers have specials. Option: Adjustable signal power. It is called “TX Power” (TX Power, Transmitter Power, Signal Level, etc. derivatives).
To change the power level of the wireless network, go to the router settings, go to the Additional Wi-Fi tab and change the mode of the transmitter.
STEP 2: what mode the router works in, whether 5G can be used
Each Wi-Fi network works in a certain mode (standard). Its bandwidth depends on it. The most popular networks are currently based on standards: 802.11ac, 802.11n, 802.11g (see Table below).
|standard||Year of development||max. Speed (theor.)||max. Speed (theor.)|
|802.11a (2,4 GHz)||2000||up to 54 Mbps||20 Mbps|
|802.11g (2,4 GHz)||2003||up to 54 Mbps||20 Mbps|
|802.11n (2,4 GHz)||2010||up to 600 Mbps (4 antennas)||60-150 Mbps|
|802.11ac (5 GHz)||2014||6.77 Gbps||1 Gbps|
|802.11ax (5 GHz)||2019||up to 11 Gbps||? (2-4 Gbps)|
So, ideally, in the router’s settings, you need to set the most modern standard to date (802.11ac (5 GHz), if you have a router running only on 2.4 GHz – 802.11n).
The important point is that if you have old devices that don’t support the 802.11n standard (such as 802.11g) connected to the Wi-Fi network, the network’s bandwidth can drop significantly! Therefore, it is highly desirable to manually translate the router to the most modern standard and connect it to the devices that support it.
By the way, to find out what standard your laptop can work on (or more precisely – a Wi-Fi laptop adapter), you need to open the command line and use the command netsh WLAN show drivers.
The line supports the types of radio modules that the device supports.
If your laptop doesn’t support 802.11ac (802.11n), the question can be easily solved by buying an external Wi-Fi adapter (now there are no bigger models than a mini flash).
By the way! Similar adapters are widely available in the AliExpressonline store.

STEP 3: disabling encryption (for weak routers)
If you have a fairly old (weak) router that cuts speed, reboots (while downloading large files, torrents, for example), hangs, etc. – you can reduce the load on it by disabling the encryption.
* The fact is that the router chip, because of encryption (authentication, etc.), is a load with which weak devices do not always cope. By disabling the encryption, we will reduce the load, and the transfer rate will increase somewhat.
However, the issue of protection I put on the background, and this method is suitable only as a temporary measure (for downloading music, movies … and so on, not particularly important cases…).
Encryption in the router’s web interface is turned off in the additional Wi-Fi network settings.
By the way, in order not to leave the network without protection, I can recommend adding to the section “FILTERing MAC addresses” at the router only the addresses of your network cards. Thus, even though the Wi-Fi network will be open, it will connect only those listed in the “white” list.
STEP 4: Try to change the width of the channel (by 20 MHz)
In general, it is believed that for the standard 802.11n (2.4 GHz) – to increase the speed of the Wi-Fi network, you need to expose the width of the channel in 40 MHz (MHz). Of course, the default router’s settings either use this width or set an “auto” mode (which also prefers 40 MHz).
But this point is relevant and works only at a good level of the signal. If the router is behind two walls and the signal level is not very high – the reverse effect can occur, the speed of access falls …
Based on the above, I recommend in the router settings in manual mode to specify the width of the channel in 20 MHz (at least for the time of diagnosis). It was often possible to significantly increase the speed of data transmission in the Wi-Fi network!
STEP 5: A few more tips for “diagnosis”
- The more devices are connected to the router – the lower the speed on each. Try to connect only 1 device, such as a laptop, with the router for the time of diagnosis;
- check to see if WPA or WEP encryption is installed in router security settings. Not only are they obsolete, but they usually load the chip more strongly than the more modern WPA2-PSK;
- The closer the device to the router – the stronger the signal and the higher the speed (usually);
- check all the devices connected to the router – are there any “outsiders” among them? (perhaps a good neighbor uses your network);
- Update the driver on the Wi-Fi adapter (faced several times that Windows 10 puts not quite the correct driver, not allowing the adapter to run at its maximum);
- check your network download to Windows: your channel may be “clogged up” by downloading some updates for programs you don’t care about. See what’s loaded with the network is convenient with the net limited (more on this here).
