Default and recommended settings for Intel® Wireless Adapters that support 802.11n. To change these settings, see Advanced Intel® Wireless Adapter Settings.
Make sure your access point (AP) or wifi router configured for 11n mode. If you are unsure whether the AP is configured to connect to 11n, contact the AP manufacturer.
Key settings related to 11n
- Channel
Controls the channel used by the AP to exchange data with client devices on the Wi-Fi network.
By default, most access points should be set to Auto. Microsoft recommends that you change this setting only if you:- Good understanding of Wi-Fi channels
- Learn how to determine the least congested link in your environment
In most cases, channel 1~14(2.4GHz) is higher than channel 36~(5GHz), but it may vary depending on the environment.
Some modern or higher performance APs can operate on multiple bands (or multiple channels) at the same time. For example, you can configure an AP to use Channel1 @ 2.4 GHz and Channel40 @ 5 GHz simultaneously.
- Channel width or channel capacity
Defines the channel width (20 or 40MHz) that the AP uses to exchange data with client devices on the Wi-Fi network. Wider channel widths provide higher performance.
For optimal performance and compatibility, enable support for all channel widths. A certain AP can only support 40MHz in the "only" mode, which prevents legacy devices that only support 20MHz from connecting to the AP.
- Communication Mode
This setting controls the type of Wi-Fi devices (802.11 a/b/g/n/AC) that can connect to the access point.
For optimal performance and compatibility, enable support for all wireless connection modes.
If you configure only 11n mode, legacy devices that only support 11a/b/g will not be able to connect to the AP.
I recently bought two Chinese USB Wi-Fi adapters on AliExpress, which I talked about in the article. And in this article, I decided to raise one very important and painful issue for many - finding and installing a driver for a Wi-Fi adapter from China. Which was purchased from some foreign online store, such as AliExpress, eBay, etc.
To begin with, I will try to explain what the general difference is between a Chinese Wi-Fi adapter, which most often does not even have a manufacturer and model, and they are usually called “USB Wi-Fi adapter 150 Mbit/s 802.11N...” (or something so) and a branded adapter, which can be purchased in our stores. I will introduce adapters from ASUS, D-Link, TP-Link, Tenda and other manufacturers represented by us. It is clear that there may be a difference in quality, reliability, etc. But as for the drivers, which are most often necessary for the normal operation of a Wi-Fi adapter, they are easier to find for branded adapters. Since a popular manufacturer has a website where you can download the necessary driver.
And if we have a Chinese wireless adapter that doesn’t even have a normal name, then it’s not entirely clear where to look for these drivers. In my case, the adapters included a disk containing all the necessary drivers. But as far as I understand, such a disk with drivers is not always available, or the drivers that are on this disk are not always suitable.
I don’t argue that there are Chinese manufacturers whose equipment is not represented on our market, but they still have their own websites where you can download the necessary drivers. For example, the manufacturer EDUP. They have a lot of different network devices. Using an adapter from EDUP as an example, we will look at the process of searching and installing software.
There are many more popular manufacturers, for example: Elisona, Chipal, Kebidu, Rocketek, COMFAST, Fenvi. These devices can hardly be found on our market (if we are talking specifically about Wi-Fi receivers), but they are very actively ordered on the same AliExpress. Well, not everyone understands where to get the driver for the adapter, which is usually called “802.11n”, or “Mini PC WiFi adapter 150m USB Wi-Fi Wireless network card 802.11n/g/b LAN" :)
If you have Windows 10 installed on your computer, then most likely there will be no problems with connecting and configuring such a wireless adapter. I've already checked. Both mine Windows adapter 10 recognized and started working with them without installing drivers. But in Windows 8, Windows 7, and even more so in Windows XP, you will most likely have to install everything manually.
Using these instructions you can find a driver for almost any USB or PCI Wi-Fi adapter. It doesn't matter whether it's branded or not. Purchased from us or in China.
Here it is also important to understand that any Chinese and “non-Chinese” (even though it is assembled there) the adapter works on a specific chip. This means that the hardware most likely installed inside it is from one of these manufacturers: Ralink, MediaTek, Broadcom, Qualcomm Atheros, Realtek, Intel. The description of the product itself usually indicates which chipset it runs on. And for this chipset there must be a driver developed by the company that actually produces these chipsets. Therefore, in order for the computer to see our nameless adapter, it is enough to find and give it the driver from the chipset on which it is built. It's simple.
Connecting and setting up a Chinese Wi-Fi adapter 802.11n
First, I'll show you how you can bypass the complicated process of finding the right driver. Perhaps we will be lucky and the computer will make friends with adapters without much dancing with a tambourine :)
Let's look at the example of the 802.11n adapter from EDUP. I have one, so everything has been tested from my own experience. There is also "easy idea wifi N", but everything there is identical to EDUP. I checked. And so, we connect the adapter to the computer. Can be directly connected to USB port.
Or via a USB extension cable. With its help, you can move the adapter higher for better reception. Just don't use a long extension cord, there may be problems.
Of course, a lot depends on the installed operating system on your PC. I repeat that in my case both adapters immediately worked in Windows 10. In the device manager they are identified as 802.11n USB Wireless LAN Card.
If the computer does not see the adapter, or rather cannot automatically install a driver for it, then try installing the driver from the disk that should be included. I had a disk with each adapter.
As a rule, the disk contains drivers for Windows, Mac OS and Linux. If there is a Setup.exe file there, then just run it and follow the installation instructions. What if it’s just a set different files in folders, then you need to install it through the device manager. Below in the article I will show you how to do this.
If your adapter appears in Device Manager in the "Network Adapters" section and the computer detects available Wi-Fi networks, then everything is ready. You can connect to your wireless network. No need to read further :)
How to find a driver for an unknown 802.11n WLAN Wi-Fi adapter?
I connected my Chinese EDUP USB adapter to a computer with Windows 7, and of course I saw the message “The software for the device was not installed.” 802.11n WLAN – The driver could not be found. This can happen even in Windows 10. Ten does not always automatically install the software.
The solution to the problem is to search for the driver by “Hardware ID”. Now I’ll show you everything in detail. If the WLAN receiver came with a disk, you can try installing the software from there. If not, follow the instructions.
I’ll immediately answer the popular question: “how can I download the driver if there is no Internet on the computer? The adapter doesn’t work yet, I can’t connect to the Internet.” This is understandable, and it seems to me that there are no options here. Either connect your computer to the Internet via cable and configure a wireless adapter, or download the necessary drivers on another computer. There is no other way.
We go to the device manager. You can open it in different ways. Through search, through "Properties" in "My Computer", or by command devmgmt.msc, which must be entered into the Run window, which in turn can be opened by pressing the Win + R key combination.
There in the "Other devices" section there should be an unknown device "802.11 n WLAN" with a yellow exclamation point. This is our adapter. You need to find out the "equipment ID". To do this, open its "Properties".
You need to paste the copied line into the search field. It will also most likely need to be shortened.
I originally had USB\VID_148F&PID_7601&REV_0000
Finds only by USB\VID_148F&PID_7601
We start the search by pressing Enter or the “Search” button.
A list with drivers for our wireless USB receiver As a rule, the first one on the list is the most new driver. You can also choose Windows version, which is installed on your computer. So that the driver fits.
My case: I downloaded the first driver but failed to install (most likely because it was for Windows 8). I downloaded the second one - everything worked. Conclusions: if it doesn’t work the first time, try downloading another one (second on the list, third).
Select the required option:
We confirm that “I am not a robot” and click on the link from which you can download the archive with the driver.
Update. Important! At the time of writing, an archive with the necessary drivers was being downloaded on the devid.info website. Now the DevID Driver Installer is being downloaded there. Use it at your own risk. Or use this site to determine the manufacturer (model) of your adapter. After which the driver can be found by searching on other sites. The best way is to visit the official website of the manufacturer of the chipset on which the adapter is built.
Save the archive to your computer. Next we extract the files and folders of their archive. If you're interested, you can open the folder. See what's there. As you can see, in my case, in the root of the folder are drivers for Windows 7. And there is also a folder with drivers for Windows XP.
If there is a Setup.exe file, you can try to install the driver by running this file. If not, now I’ll show you what to do.
Install the driver for 802.11n WLAN Adapter from the folder
Go to the device manager again. Right-click on "802.11n WLAN" and select "Update Drivers".
Click on "Search for drivers on this computer."
If everything is fine, the software installation process will begin and a message will appear that the driver installation for the 802.11n USB Wireless LAN Card device has been completed.
Our Chinese USB Wi-Fi adapter appeared in the device manager.
Wi-Fi on my computer worked immediately. A Wi-Fi network icon appears with a list of wireless networks available for connection.
That's all, the installation and configuration process is complete. I really hope everything worked out for you.
Additional information
If after connecting the adapter to the computer’s USB port there is no reaction at all (no message, device itself in device manager, sound signal) , then try connecting to a different port. Without extension cord (if you have one). Also check the adapter itself on another computer. Maybe he's just not working.
It often happens that everything seems to be fixed, the driver is installed, but the computer does not see the Wi-Fi network. And a red cross next to the wireless network icon. Based on my own experience, the problem is that the WLAN auto-configuration service is disabled on your PC. You just need to run it according to the instructions. Or the adapter itself cannot catch the Wi-Fi network. Perhaps the antenna is not screwed on properly (if there is one), or you need to raise it higher. You can use a USB extension cable for this.
To summarize, I can say that the process of installing the driver and Wi-Fi settings An adapter ordered from a Chinese online store is not much more difficult than installing the same adapter from some popular manufacturer. Especially if Windows 10 is installed on the computer. It’s just that when we have an adapter from TP-Link, for example, then we have a model for which, if necessary, we can find a driver on the company’s website. And with an adapter that doesn’t have a name or model (802.11n is the version Wi-Fi standard networks), you need to tinker a little.
I look forward to your comments with questions and advice.
This spring I switched to wireless internet, bought a 4G modem from MegaFon and a HAME A15 router for distributing Internet via WiFi.
The phone and tablet receive WiFi using the built-in adapters, but my old PC is not trained for this. Of course, you can connect it with a wire, but I somehow don’t like wires (or I just don’t know how to cook them over a fire:), so I bought a WiFi USB adapter for it, the so-called WiFi whistle, but what kind of whistle is it, rather WiFi -pimple :)
And as you know, there are problems with pimples...
For those who are too lazy to read, I’ll immediately say that the WiFi-pimple is quite suitable and you can safely take it, it works and does not require any dancing with a tambourine under Windows, I can’t say anything about other systems, I haven’t tried it, but I read in the reviews that there are drivers for Linux don't update.

A small photo session of a WiFi pimple:
Lounging on the rug
Stuck in the PC
Let's eat
Giblet, open carefully, the latches are fragile, the photo shows a broken one. 
The attentive reader has probably already noticed the non-original wiring soldered to the WiFi pimple? The question is - why?
I’ll start from the beginning, the WiFi-pimple is very small and sits deep in the USB socket, almost not protruding, this is good, BUT! The devil is in the details!
I noticed that the speed over WiFi, especially for upload, is very low from a PC, although the distance from the router to the WiFi pimple is only 1.5m. But when I connect the WiFi-pimple through an extension cord, even a short 15cm one, the speed of return increases significantly! This made me very worried, I can’t eat, you know, I want fast WiFi.
It became clear that the router “hardly hears” the WiFi pimple, and plus the PC with its iron case shields the WiFi pimple from the router, which is located a little behind and higher, near the wall: 
Well, aren’t we radio operators!? The radio operator's first commandment is: If the connection is bad, connect a good antenna!
No question, good or bad, but I soldered the antenna, first 1/4 of the wavelength (about 3cm) and OPEN, the speed immediately increased and the signal from the WiFi pimple became 2-3dBm higher. I decided to try 3/4 wavelength (about 9cm), it was better, the signal increased by 3-4dBm and the speed began to remain consistently high.
Conclusion - size matters :), even a small WiFi pimple with a large antenna can be successful. Speeds after “collective farming”: 
I also soldered the same antenna (3/4 wavelength) to the HAME A15 router, the connection with the tablet through 2 walls diagonally became more stable, now I can watch movies in the kitchen calmly, without interruptions. I did not disconnect the built-in antennas, the flight was normal for several months. 
You can safely buy a WiFi pimple, even with the current price of wood, it’s not expensive, don’t forget to look for discount coupons.
That’s probably all for now, I’ll wrap it up, I hope my “collective farming” will be useful to someone, and if not, then don’t throw your slipper too hard, the pianist plays as best he can! I haven’t written for a long time, the keys on the keyboard are completely rusty, so all the notes in the review are not mine, it’s the keyboard’s fault.
Happy New Year and Merry Christmas to all Muskovites and Muskovites (I hope at least one has read this far:)! Well, it’s time, we can start rehearsals this Friday!
Hi all!
I assembled a computer out of trash for the garage, and the question arose of connecting it to the Internet. The garage is next to the house, of course there is wi-fi. I chose the most inexpensive receiver.

Interface: USB2.0
Transmission Distance: Indoor up to 100m, outdoor up to 150m (it is limited in an
environment)
Ordered 2 pieces
The receiver is small, the transmitter of a wireless mouse is the same size.
We connect to the computer, identified as Realtek RTL8188CU Wireless LAN 802.11n USB 2.0 Network Adapter
The distance to the router is 3 meters, the receiver is connected to the rear USB connector of the PC. The reception is good, which is not surprising.
Let's check the speed. My Internet is not fast, up to 20 Mbit (yota). so there is no way to fully check. The adapter does not slow down the speed up to 20 Mbit, that's for sure :)
Everything is fine at home, but what will happen in the garage?
The distance is approximately 5-7 meters, the obstacles are the wall of the house (wood) + foam block.
PC configuration - mother 478 socket, 4 3 GHz processor, 768 RAM (up to 1 GB additional) 
I took the second receiver, installed the drivers, connected to the network and then... no Internet!
I noticed that the second receiver was defined a little differently, namely as Realtek RTL8188CTV Wireless LAN 802.11n USB 2.0 Network Adapter 
Strange ip 
I checked it on my main PC and laptop, and the Internet doesn’t work either. I thought it was the drivers, tried different ones, even registered the ip - nothing.
I was about to open a dispute, but then I thought - what if I disable network protection?
I turn it off, the Internet has appeared. Already makes me happy. But I didn’t want to leave the network open, so I created a guest network with wep encryption(Internet does not work with wpa).
Yes, I know that wep is easy to hack, but what can you do)
So, there is Internet in the garage, but the signal is below average 
But nevertheless, the speed is enough to use the Internet, and the video also works fine and is not interrupted (360p) 
It's time to look inside the device.
Opening up the “problem” receiver 
And now it works fine 
There are zero differences (except for the markings on the chip), but why are they defined as different devices? Fake?
On the topic of heating. It is there, the USB connector itself gets very hot if the transmitter is connected to the hub/front port of the PC. If you connect it to the rear connector of the PC, the heating is significantly reduced.
This is understandable - the dispersion area is larger.
That's probably all, the receiver works, there are no interruptions in communication, everything suits me.
Thank you for your attention!

I encountered this problem when buying a Wi-Fi adapter at one of the most low 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
