Wi adapters 802.11 n usb. Select a Wi-Fi adapter. Professional: expansion boards
Wireless technologies are increasingly included in our daily life. Until recently, the optimal way to connect a personal computer to local network and the Internet, a twisted pair connection was considered, which provides a speed of 100 Mbit/s (and even higher) and excellent stability. However, progress does not stand still and there are already quite a lot of wireless devices on the market that can provide fairly fast and reliable communication.
If you already have a wireless router installed in your home or office (aka router), which allows you to organize wireless network, then to connect to it personal computer or smart TV you will need a wi-fi adapter . This will be a good alternative to a wired connection, which requires labor-intensive cabling.
There are hundreds of models of wi-fi adapters on the market. How to choose the right model?
Wi-Fi standards
First of all, you need to decide on the supported standards. wireless communication. Modern devices can support the following standards (in order from slow to fast): 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac.
The 802.11n and 802.11ac standards are the most modern and fastest. At the same time, the 802.11n standard was adopted in 2009 and this moment Nowadays, most wireless devices support it. The 802.11ac standard was adopted in 2014. Devices that support this standard, are produced in smaller quantities and are usually more expensive. The remaining standards are considered obsolete, but all modern devices also support them to ensure compatibility.
Below is a summary table reflecting the main differences between the different standards.
Wireless connection speed
The speed of the wireless connection depends on the supported standard, as well as the number of transmitting and receiving antennas. In the 802.11n standard, the maximum data transfer rate per antenna is 150 Mbit/s, in the 802.11ac standard – 433 Mbit/s.
It should be noted that the theoretical data transfer rate in all standards differs significantly from the real one. Firstly, wi-fi devices spend half their time transmitting data and the other half receiving. Therefore, the theoretical speed must be immediately divided by 2 (which is reflected in the table). Secondly, along with useful information, quite a lot of service traffic is transmitted, including that necessary to ensure noise immunity.
That is why, even under ideal conditions, the data transfer speed from one device to another will be 2-3 times lower than the theoretical one (the one indicated on the box), depending on the class of the device. Budget models, as a rule, show noticeably more modest results than top-end adapters. If there is interference in the form of walls or household appliances, the speed may drop several times more.
Frequency range
Wireless devices Currently they can operate in two frequency ranges - 2.4 and 5 GHz.
Number of antennas
Wireless communication standards 802.11n and 802.11ac provide the ability to use multiple antennas (MIMO, from the English Multiple Input Multiple Output), which increases the connection speed by a multiple. The 802.11n standard allows the use of up to 4 antennas, 802.11ac - up to eight.
To achieve maximum speeds and a stable connection, it is advisable to choose wireless equipment with multiple antennas. As a rule, adapters and routers with multiple antennas are more expensive.
Supported OS and other hardware
Manufacturers of wi-fi adapters, as a rule, release drivers for their devices for most operating systems. However, older versions of operating systems (such as Windows XP) may not be supported. There may also be problems with device support on new operating systems.
Therefore, when choosing an adapter, you must definitely pay attention to the list of supported operating systems.
If you purchase an adapter to connect to a TV network, it would be a good idea to read the list of supported adapters on the manufacturer’s website (if available).
Conditional price ranges of wi-fi adapters (note that price policy manufacturers may vary greatly):
adapters costing up to 1200 rubles. As a rule, these are inexpensive 802.11n adapters that have either an internal antenna or 1-2 external antennas. Claimed data transfer rates range from 150 to 300 Mbit/s. Provide acceptable communication quality at an affordable price.

I encountered this problem when buying a Wi-Fi adapter at one of the lowest prices on ebay.com. I make purchases on this site quite often and, as a result, I did not notice some nuances, namely the lack of a link to download drivers for the adapter. The laptop found the device, but could not find the driver. I had to “climb” the Internet in search of any information. In general, we managed to find everything, figure it out

Video Installing wifi, Usb WiFi adapter 802.11n Wireless installation and use of the ARNO94LD channel
For more than a year now I have been using a fanless mini computer (with a passive cooling system) from Hystou on Core i5. I am very pleased with the computer, after time it still works well and fully satisfies my needs. , if anyone is interested. Almost the only drawback for me initially was the weak WiFi module and the lack of support for the 802.11 ac standard. The computer has a combined WiFi + Bluetooth module Broadcom BCM94313HMGB, which is connected via PCI-E.
It only works in the 2.4Ghz range, and besides, it does not have the best sensitivity; in the next room the speed already drops noticeably. And this is even despite the remote antennas. In general, I then thought that I would temporarily use it, and then buy something with support for 802.11 ac on Ali, since there is plenty to choose from. But as you know, there is nothing more permanent than temporary. My friend prompted me to buy it because he highly praised this adapter. The asking price was only $5, so I ordered it without hesitation.
The Wifi adapter is in a transparent package. Inside there is a cardboard insert that states that it supports the IEEE 802.11ac standard and can operate in two bands 2.4Ghz/5Ghz. The specified speed is 600 Mbps.
On the reverse side you can already read the detailed characteristics and here it becomes clear where the 600 Mbps figure comes from. The Chinese simply added up the speeds in two ranges :) If taken separately, then in the AC standard the speed will be up to 433 Mbps, and in the N standard - up to 150 Mbps.
Inside the cardboard insert I found a mini CD.
It contained drivers for Windows, Mac OS and Linux. Most likely, drivers are needed for old computers running Windows XP, possibly Windows 7. You don’t need to install anything on Windows 10, the drivers installed automatically.
There is also a user manual in PDF on the disc, and Adobe Reader is included to open it.
The adapter itself is miniature in size, 3 times smaller than a regular USB flash drive. There is a WiFi icon and a large AC logo on the case. A small blue LED illuminates the case and shows the operation of the device - it blinks when the network is active.
WITH reverse side nothing interesting.
Total length - 2.9 cm.
But a good half is occupied by the connector itself, that is, if you insert it into a laptop or computer, it will protrude only 1.6 cm. For a desktop computer this, of course, does not matter at all, but in laptops - the less, the better.
When connected to a computer it is detected as Realtek 8811CU
Well, actually what I took it for was speed. My computer is in the room next to the router and because of the wall the speed drops a little. On the old WiFi module, the maximum I could get was 45 - 48 Mbps. And that's the maximum. Often channels intersect with neighboring ones and the speed drops to 20 - 25 Mbps.
This, of course, is obscenity, especially considering that I have a tariff plan of up to 200 Mbps and a modern dual-band router Mi Router 4. There is not a single soul in the 5 Ghz range, all channels are free. In general, I connect the adapter and do another speed test - 168 Mbps.
The speed has increased by at least 3.5 times, and the connection has become more stable. Now my neighbors don't bother me and I can enjoy the benefits of my tariff plan:) As of today, I have been using the adapter for 3 weeks and during my use I have not had any comments. In general, I got exactly what I expected. Now the PCI-E slot is also free on the computer.
This is how it looks on the computer (next to it is a larger adapter, this is for a wireless mouse + keyboard)
Today I ordered another one for an old laptop; it wouldn’t hurt for a “pensioner” to learn how to quickly download torrents :)
I bought a WiFi adapter on Aliexpress for $5. The seller is reliable with a rating of 98.2%, he already has 865 orders for this particular adapter and only 1 of them is negative. In general, I recommend it.
Long range Wi-Fi standard 802.11ac might be considered the most compelling reason to retool. But in order for the end device to benefit from both this characteristic and the high speed, it is necessary to upgrade to the 802.11ac standard. The easiest way to do this is with USB adapters.
To do this, deactivate the old adapter by going to “Control Panel | Network Control Center and shared access| Change adapter settings". Right-click on the appropriate adapter and select “Disable”. After that, insert the new adapter into the PC’s USB port and install the drivers.
If your computer only has USB 2.0 interfaces, it is better to choose Wi-Fi module 802.11ac connected to the PCIe bus in the PC to avoid problems. For desktop computers Replaceable PCIe cards are available to match the size of the 2.5 cm PCIe slots. External antennas are connected by cable and placed optimally.
For the most part, laptops are relatively easy to replace the built-in WLAN adapter with a better one. new model. However, there is a problem here, which is that the antennas built into the laptop must support the 5 GHz WLAN band, which is often only the case with expensive high-end solutions. Converting antennas to 5 GHz is very difficult. Is your device compliant? this condition, you can find out through the adapter settings in the Control Panel.
Universal option: USB adapter
Many manufacturers offer USB adapters supporting the WLAN standard: we tested four of them (three with USB 3.0 and one with USB 2.0). The best-proven device is the Netgear A6210 with two AC channels (nominally 866 Mbps), in which the bulky folding antenna plays a significant role.
A USB extender with a stand is also useful, with which you can position the A6210 so that the signal is received most efficiently. Netgear's device is, on average, faster than other WLAN modules tested. Comparable power is provided by Asus's USB-AC56 adapter with its external folding and rotating antennas.
The slowest in testing was the tiny D-Link DWA-171, which has only one AC channel (nominally 433 Mbit/s) and only USB 2.0, which hardly allows it to outperform a WLAN adapter of the “n” standard (nominally 300 Mbit/s). /With). Close-range measurements clearly show how USB 2.0 slows down data transfer. However, given the compactness and low price, we can assume that the power is normal. For long range, you will need a larger device with a wider range of settings.
Professional: expansion boards
It is optimal to connect a PC to a router via a gigabit LAN. However, if the cable gets in the way too much, a good alternative could be a WLAN-ac expansion card, which at normal “in-house” distances will not require big compromises in terms of connection speed and stability.
Compared to a USB device, the expansion card can also work in a PC with USB 2.0 without loss of speed, without taking up scarce USB ports 3.0 on newer PCs. Both boards we tested correspond in size to PCI-Express slot, which can be found on PCs no older than 10 years. They work with large external antennas that can be optimally positioned thanks to the long cable.
Unlike Intel boards AC-7260, model Asus PCE-AC68 is an expansion card for a desktop PC in its purest form. This solution can turn its advantage of having three AC channels (nominally 1300 Mbps) into impressive data transfer speeds only at a distance of 5 meters and within line of sight. For such a short distance, running a LAN cable is probably a more practical and cheaper option. In our test (ten meters, over a wall), the speed dropped significantly.
The Intel AC-7260 adapter showed more stable results. Wherein we're talking about about a small PCIe module for installation in a laptop, which Intel ships complete with an adapter card for desktop PCs and an external antenna. At close range, the module with a nominal speed of 866 Mbps does not provide the same high-speed data transfer as the Asus model, but over long distances it demonstrated much greater stability and earned our recommendation for use in desktop PCs.
If you want to convert your laptop to the Wi-Fi 802.11ac standard, buying an Intel AC-7260 PCIe Mini Card without a desktop PC conversion card for about 2,000 rubles is also a smart option. Besides it, the only thing left is the slower Intel AC-3160 model.
