Compact USB Wi-Fi module. Review of TP-Link TL-WN823N. Compact USB Wi-Fi module Tp link tl wn823n what is it for?

Due to the fact that the Windows 10 operating system is under constant development, some of its components may not function. In the latest builds (16199, 16215 and others), it is impossible to make the TL-WN823N USB Wi-Fi adapter work as an access point, since there is a problem with the Mobile hotspot. To verify this, enter the following command into the command line interpreter (it must be run as Administrator - WIN+X keys --> Command line(administrator)):

NETSH WLAN show drivers

The result will be something like this:

C:\WINDOWS\system32>NETSH WLAN show drivers Interface name: Wi-Fi Driver: TP-Link Wireless USB Adapter Vendor: TP-Link Technologies Co., Ltd. Provider: Realtek Semiconductor Corp. Date: 10/26/2016 Version: 1030.11.503.2016 INF file: netrtwlanu.inf Type: Native Wi-Fi Driver Radio types supported: 802.11n 802.11g 802.11b FIPS 140-2 mode supported: Yes 802.11w Management Frame Protection supported: Yes Hosted network supported: No<==== Authentication and cipher supported in infrastructure mode:

"No" means the system cannot operate as an access point. Also in Settings --> Network and Internet --> Mobile hotspot there will be the following message:

"Unable to set up mobile hotspot. Please turn on Wi-Fi."

Trying to enter the "netsh" command will also not lead to success:

C:\>netsh wlan set hostednetwork mode=allow ssid=Titanium key=999999999999 C:\>netsh wlan start hostednetwork Failed to start the hosted network. The group or resource is not in the correct state to perform the required operation.

But there is still a way to get around this problem using the VirtualBox program. The idea is very simple - you need to install VirtualBox with support USB port ov, then install the Windows XP or some other operating system in it, and run a program in it to create a hotspot. Here's what you'll need for this:

• Working Windows 10 build 16199 or later;
• The VirtualBox program (VirtualBox-5.1.23-115901-Win.exe or a later build), you can download from here or here;
• Drivers for wireless USB adapter TL-WN823N TP-Link, latest versions you can download, download drivers for both Windows 10 and Windows XP systems;
• Operating disk Windows system XP SP3 (or iso file);
• OSToto Hotspot program (OSTotoHotspot_24984.1.9.4.exe, md5 =), you can download from here (Free Utilities --> OSToto Hotspot)

What should be done:

Try connecting to this access point again using the SSID and password you entered earlier.

It is also worth noting that it is better to disable the power saving mode for all adapters. To do this, you need to left-click on the adapter icons in the system tray of Windows XP, then click on “Properties”, then on “Configuration”. In the tab "Power Management" uncheck "Allow this device to turn off to save power", do the same for all adapters.

In addition, there is another problem with the TL-WN823N USB Wi-Fi adapter - if you connect it to certain USB ports on the motherboard, the computer may freeze at startup. This occurs because the TL-WN823N adapter draws too much current, overloading the USB port. But if you connect the adapter to another port, to a hub or card reader with a USB connector, then everything works fine.

The above method for creating an access point works not only with the TL-WN823N adapter, but also with other adapters. As noted above, almost any modern operating system can be used as a guest operating system, for example, Windows 7/8, Ubuntu, etc.

After pressing the button Connection you need to enter the security key password phrase (in our case 12345678 or, if you changed this password, then masha+vova=love) and the Internet will be connected to the laptop. The Internet is launched through any browser, both with the desktop PC turned on and without it. If only the router was turned on.

Tabletop omnidirectional 8dBi antenna TL-ANT2408C

The TL-ANT2408C wireless desktop antenna operates at a frequency of 2.4-2.5 GHz with a gain of 8 dBi and can significantly increase the range of the wireless signal and improve the quality of the connection. The antenna is equipped with an RP-SMA plug, which ensures compatibility with most wireless devices- rice. 38.21.

Rice. 38.21.

Replacing the stationary antenna of the router (access point) with the TL-ANT2408C will significantly increase the strength and range of the wireless signal. Since this antenna is omnidirectional, there is no need to turn it in one direction or another to get a clearer signal - the antenna receives and sends signals in all directions.

Note

dBi (dBi)- this is a decibel compared to "i", that is, in relation to an isotropic emitter - an ideal antenna, the radiation pattern of which is a sphere, the gain of which equal to one and whose efficiency is 100%. dBi (dBi) characterizes the antenna gain and its directional properties compared to an isotropic radiator. Strictly speaking, if they say that a given antenna has a gain of, for example, 8 dB, then what they really mean is 8 dBi.

Wi-Fi adapterTP-LINK TL-WN725N

An inexpensive and compact Wi-Fi adapter TP-LINK TL-WN725N is shown in Fig. 38.22.

Characteristics:

• Standard wireless communication- 802.11n, frequency 2.4 GHz
• Max. speed wireless connection- 150 Mbit/s
• Connection interface - USB 2.0
• Information security (data encryption mode) - WEP, WPA, WPA2, 802.1x
• Transmitter power 20 dBM

Note

dBm is a decibel compared to "m", in this case relative to a milliwatt. In other words, this is the value of how many decibels a given power is greater (or less) than 1 mW.

Wireless mini USB network adapter (USB WLAN) TL-WN823N

Wireless mini USB network adapter TL-WN823N is designed to connect a laptop or desktop computer to a wireless network. Wireless connection speed up to 300 Mbps. - rice. 38.23.

The adapter has a software access point function. By enabling this mode, users can share access to other Wi-Fi devices (laptops, smartphones or tablets) from their laptops or personal computers with wired connection. The adapter allows you to configure security with one click of the WPS (Wi-Fi Protected Setup) button. Users can instantly set up network security with one click on the router's WPS button, after which a connection is automatically established protected by WPA2 encryption mode, which is considered more secure than WEP encryption. Not only is this faster than normal security setup, but it's also more convenient because users don't even have to remember a password.

USB Wi-Fi adapter TP-Link TL-WN822N

The TP-Link TL-WN822N model does a good job of searching weak signal Wi-Fi, as it has two powerful omnidirectional antennas with a gain of 3 dBi (this is more than a standard laptop). The adapter has a QSS button for quick setup secure wireless connection, as well as an LED activity indicator. QSS function (Quick

In this article I will share with you my experience of upgrading a wireless USB network adapter
TL-WN823N.
This modernization was a compulsory measure!

I’ll try to explain everything in as much detail as possible, the article will be long.

I purchased this wireless adapter for future integration into desktop computer(let me clarify: you need to connect it to the motherboard additional USB outputs, secure them inside the computer, plug in the adapter), it is small in size and has a high data transfer speed of 300 MB/s (why just such an adapter: I didn’t want to install PCI, I couldn’t install PCIEx x1 because the video card was in the way).
From the beginning everything was fine, I didn’t use it often, but when I started using it actively, problems started!
Problems were related to dumps Wi-Fi adapter, loss of Internet access on Windows 8\8.1\10, installing drivers of different versions did not help, it was strange because... the adapter is not old. But there is an adapter, and I want it to work normally + this is a matter of principle: D. It is noteworthy that it only fell off under load, let’s say you start downloading a torrent and the adapter goes for a walk.
In another such dump, I freaked out, etc. I've already tried and reread everything I can, I just took it apart and took it apart! And this is what I saw under the body:

Oops, here's a chip for you! on which, with the naked eye, you can see traces of overheating of the chip (Realtek); under load, the chip heats up and the adapter begins to work incorrectly.
So why does it get so hot?
In the following picture I have highlighted the areas of the adapter with different colors, and I will try to explain why it gets so hot:

This is all due to the small (miniature) size of the adapter, I highlighted in red the approximate location of the chip (in general the chip does not get very hot), in green I highlighted the soldering area USB plug to the board, blue “housing” of the plug. And this is what we have: with active using USB devices, let's say a flash drive, you can notice the heating of the USB plug, and so (apparently) with active use, the installation site of the plug (green) and the plug itself (blue) heat up, as a result, the base on which the chip is located is quite hot, and the chip itself also adds temperature under load, subsequently we have overheating!.. But with a light load the adapter can work calmly, the load can be controlled by the driver operating system or the user himself. There is also motherboards who have increased voltage USB ports, For fast charging smartphones via USB cable (optional). In general, as you can see, the design of the adapter is extremely poorly thought out, I would have made it a couple of centimeters longer, and it wouldn’t have done such weird things.
It would be a shame to throw it away =), let's try to modernize it!
If the chip gets hot, then you need to come up with cooling for it, it will be a radiator, I cut off a piece of the radiator from the chipset of the old motherboard:

And I carefully glued it to the chip using super glue “Super Moment for Shoes”, like this:

This should be enough. The radiator will take on the main heat.
Well, since they’ve already started to modernize everything here, why not add power to the adapter? I have one right at hand top cover laptop from which you can remove the Wi-Fi antenna!
Here she is:

Now carefully solder the antenna from the laptop to the adapter antenna, like this:

Hooray, the adapter is equipped with a mega antenna: D
Here's what it looks like in general:

The antenna can be glued to different surfaces, which is very convenient. Let me remind you that all this will be located under the computer case, so it can look whatever you want: D.
Here's what it looks like on a computer:

Result:
After all these manipulations, the adapter began to catch Wi-Fi networks better, the heatsink on the chip itself gets quite hot from time to time, which confirms my theory about overheating!.. I downloaded the torrent at a speed of 5.3 MB/s, everything is ok. I glued the Wi-Fi antenna under the front of the case, which improved the signal quality. In general, everything went well =)

Leave your opinion\constructive criticism\corrections if I made a mistake somewhere!

P.S. Taking into account all the comments, I must admit that the heating is probably not caused by the USB plug, which means that most likely there will be a second part.

Thank you for your attention, I hope this article was useful to someone =)

This page is entirely dedicated to the TP-Link TL-WN722N Wi-Fi adapter. A very popular model that has been successfully sold for a long time. Great adapter for connecting to Wi-Fi networks desktop computers or laptops. There is an external antenna, which is undoubtedly a big plus. Thanks to it, the adapter catches the Wi-Fi signal better. I would also highlight among the advantages easy setup. No problems with drivers (well, almost none). Works stably in Windows 10, Windows 8, Windows 7, and Windows XP. There are problems when the computer does not see the adapter, or the TL-WN722N does not see the Wi-Fi network. But this is usually easily resolved and usually occurs due to operating system settings. Well, or due to the fault and inexperience of the user himself. In this article we will look at the most popular problems.

At the time of writing this article, I have been using the TP-Link TL-WN722N V 1.0 Wi-Fi adapter for several weeks. I have a laptop, I used to connect via the built-in Wi-Fi module. But I had to move the laptop further away and put it on a shelf under the table. And Wi-Fi began to catch very poorly (1-2 bars). I had to connect this adapter through a small USB extension cable. I didn’t configure anything on Windows 10 at all, I just connected it and the system installed the drivers itself. True, in my device manager it appears as “Atheros AR9271 Wireless Network Adapter”. But everything works well.

There are two hardware versions of the TP-Link TL-WN722N adapter (there is V3 on the official website, but there is a driver only for MAC, at the time of writing this article). The hardware version V1 runs on the Atheros AR9271 chipset, and V2 on the REALTEK RTL8188EUS. The official website has drivers for both Windows, MAC and Linux. The characteristics will not be described, they can be viewed on any website. Wi-Fi network speed up to 150 Mbit/s.

Another important point. Through the TL-WN722N adapter you can not only connect to wireless networks, but also distribute the Internet via a Wi-Fi network. It can work as an access point (SoftAP). You can set up distribution as follows: using Windows, and through a proprietary utility. Below I will write about this in more detail and provide the necessary links.

Installing the driver on TP-Link TL-WN722N

The entire process of setting up almost any Wi-Fi adapter comes down to installing drivers. Of course, first you need to connect the adapter itself to your computer or laptop.

Just plug it into a USB port.

Advice: If you have Windows 10, then do not rush to install drivers from the disk or from the website. Most likely, the system itself will select and install the driver. A message will appear whether the device is installed or not. And the adapter itself should appear in the device manager. Well, and the Wi-Fi connection icon on the notification panel. If Windows 10 cannot install the adapter itself, or it will not work well (disabled, low speed, ping), then install the driver from the disk or the TP-Link website.

For the second hardware version (ver. 2) there is a driver for everyone Windows versions, including for Windows 10. For the first hardware version (ver. 1) there are no drivers for TL-WN722N for Windows 10. But, as I wrote above, everything worked automatically for me. On the Internet they also write that drivers from Windows 8.1 or from a disk are suitable.

Advice: To find out the hardware version of your adapter, look at the sticker on the adapter itself.

If the hardware version is not listed there, then it is V1.

The kit includes a disk with drivers and utility. You can install everything from there. Just run the disc and follow the instructions.

Advice: As a rule, a utility for managing the adapter is installed from the disk. You can also download it from the official website. There is no particular need for this utility. So I advise you not to install it. During the installation process from disk, you can cancel the installation of the utility.

To download the driver, go to the link http://www.tp-linkru.com/download/TL-WN722N_V1.html, select your hardware version, go to the "Driver" tab and download the first file in the list for Windows.

Installation:

Windows 10 and Hardware Adapter V1

If everything is not installed automatically, then you can try installing the driver from the disk, or from Windows 8.1. Like this:

Or use the method described above.

Possible problems and solutions

Let's look at the most popular problems that users encounter most often.

If you encounter any other problems, write about them in the comments. Especially if you know the solutions :)

I decided to connect my desktop computer to wi-fi... and this small module helped me with this without any problems

Due to changes in my apartment, the question arose about moving the router to another room. Well, since two computers are connected to the router via cable, it was decided to transfer one to a wi-fi connection.

I have trusted TP-LINK for a long time... I also have a router from their company. Therefore, the choice fell immediately on him.

The dimensions, as you can see, are quite small, like a flash drive - 40.95 mm by 19.48 mm

The kit includes a warranty card, instructions, a disk with drivers and the module itself. Everything is in Chinese, for their domestic market.

I was pleased with the disc... it has a non-standard shape, to be honest, this is the first time I’ve seen one like this :)

There's even a date on the warranty card

Instructions are unlikely to be needed, because nothing is clear what is written... but from the pictures it is intuitively clear what to press where

The body of the module is all glossy... and immediately collected all my fingerprints, but these are not glasses, so I don’t see any special problems in this

But there is also a small fly in the ointment... and it lies precisely in software on disk. It is entirely in Chinese, from autostart to the application itself. In general, I poked around, looked at the pictures in the instructions and then it dawned on me... after all, tp-link has a website with all the manuals, drivers and programs... and they are most likely more recent than on the disk. In general, the disk can be thrown into the trash and the instructions too, everything is on the website in English.
Everything was installed quickly and smoothly, there was no need for shamanism at all.

What was pleasantly surprising was the range. I think I saw everyone who distributes the Internet throughout the whole house, or at least in the front door, and the house is nothing less than reinforced concrete blocks, 9 floors and 3 front doors. I have never seen so many, even though I had a lot of devices on my hands. Overall, a solid 10 in this regard!

It connected to my router without any problems, the signal level is 100% (the router is in the 3rd room, I am in the 1st, in total there are 3 walls)

And finally, the speed test, it corresponds to my package and is absolutely identical to the cable connection

When data is being transferred, the blue LED on the device flashes.

I have been pleased with TP-LINK products for several years now... the router has been working for about 3-4 years. And this device turned out to be quite successful and fully met my criteria.
