The perfect purchase for me, exactly what I was looking for!

I recommend it, but alas, if you want WI-FI on Vista, then alas, forget about it ( Has pros: Ease of setup, in Windows XP at 50% of the driver installation, it’s already what kind of network the adapter started to find, I didn’t try to distribute WI-FI, but I think everything will be fine there too, online video is fine, FB and other social networks surf perfectly, they say it’s bad to catch through 2 walls, but everything is fine with me, and the scale is completely lit) Some cons: There are…

The product is very low quality, not what you need at all.

If your nerves are dear to you and you need to upload any large volumes, do not buy this adapter. Not only does it not give out more than 3 megabytes per second. it also falls off under load and hangs for 10-15 seconds. In order for it to work at least somehow, I had to lift it on an extension cord as close to the router as possible. In general, I do not advise, it is acceptable only for surfing pages and not far from the router.

  • - Small size - Price - Easy to install
  • - Glitchy, often freezes - Weak signal strength - Very low speed - Sensitive to interference from the system unit

Not the best quality, but overall not bad.

My hardware version is V4. There are no drivers for Win10 x64 on the manufacturer's website, only for version V5 there is a driver for Windows 10. Has pros: The price is not heated, under Win10 x64 it works without installing drivers. Cons: The network falls off. When under load (in the CS:GO game), it loses connection for several minutes, which is very critical. In other applications it works stably. Does not work well in USB 3.0, 3.1 ports - loses or does not see the network.

Bad! I am not satisfied with the quality of the product.

I bought it in order to improve signal reception from Beeline WiFi. But . I have a netbook from Asus, so it catches the network better. The test was carried out in the same place. On a netbook, by the way, the network card also has an Atheros chip, but it works better. Bottom line: useless!

The product is good, there are only a few minor flaws.

I bought the first one that came across, since the network card died, and the Internet is needed. If it didn't fall off, it would be a great adapter. I have been using it for more than a month now, I am satisfied with the speed. With its pros: Gives almost the maximum speed declared by the provider. (the old adapter gave out half, and that's not a fact) Different cons: Falls off. The first time it fell off in the first week of use, 1-2 times a week it definitely falls off.

Terrible quality, disappointed with the purchase.

I took 6 pieces, all 6 do not pull the remote desktop at minimum, constantly disconnection, brakes, etc. , the speed cuts to a minimum, ping is just space. In short, the product is completely crap, I highly do not recommend buying it.

Good and quality product, but there are flaws.

Some pros: Inexpensive, but it was very inexpensive. Lost connection a couple of times. Different cons: Overheating, and the more you use it, the more serious it is. Periodically there are drawdowns of the Internet, and, accordingly, lags. The connector is slightly bent from frequent use.

The quality exceeds all expectations, I recommend to buy.

After connecting to the router, the download speed was 1 Mbps, although all other devices have 10 Mbps (the maximum that the provider gives). Tried everything. Then I read somewhere that you can try the driver from the manufacturer. I downloaded the branded one and lo and behold - it also became 10 Mbps! Has pros: After the correct settings (proprietary driver) - everything flies! Has some cons: After thecomrrect settings (proprietary driver) - everything flies!

The right product for me, the price suited me.

After making the settings it works great. For Windows, you need to select in the power settings so that the axis does not turn off to save energy. And for Linux, here is the manual: Decision: $ sudo nano /etc/network/interfaces At the end of the file add: iface wlan0 inet dhcp auto wlan0 Attention! Lines in that order, on thecomntrary did not work. If it doesn't help, install the drivers: sudo apt-get ate sudo apt-get install git git clone cd rtl8192eu-linux-driver make sudo make install…

  • Picks up a good signal
  • On Linux, it requires additional configuration, because can fool and fall off.

Total disappointment, the product is terrible.

Very weak signal, even in comparison with the adapter built into the laptop. It does not catch even half of the networks that the built-in one catches. Nothing good in Linux either. Switches to monitor mode, but the injection can't even do it. I bought it myself, I thought version 2-4 would come across. It turned out to be version 6, where the RTL8192EU chip is installed. In short, complete seams. I do not advise.

  • none
  • RTL8192EU

Great value for the money, definitely recommended!

The router is located at a distance of 12 meters from the PC in the hall closet, behind three partitions: two - drywall and one - brick 160 mm. The signal loss is insignificant for my conditions: 17m, bit-reception, 32.72m. Bit-distribution, at a delivered speed of 100m. Bit. The previous adapter (of a different brand) could not withstand the load and the hot summer, it constantly took off. * Computer workstation for designing in BIM.

  • On-the-fly connection: plug into USB port and you're done (Windows 10_64bit), size and design, does not heat up, works steadily. Signal power-20db. Price. Exceeded my expectations.
  • Haven't found it yet.

Excellent quality, absolutely not expected for such a price.

I advise everyone who will buy this adapter in Ubuntu to immediately roll fixes to official firewood out of the box. Out of the box, rtl8192cu is used. I had problems with it, the load indication on the adapter did not work, the green light wascomnstantly on and there were breaks every 3-4 hours under heavy loads, active surfing or music in the background of surfing. And sometimes it dropped to 3-2 sticks in the reception. So, there is a fix for these firewood. To do this, open thecomnsole…

Not happy with this product, bad in use.

The device does not correspond to the price and the declared speed. A 300Mbit link shows 5-6m from the point, behind the inner wall. So the sensitivity is good. With overheating, I also did not see any problems, no matter how you download torrents - barely warm. But with the speed - trouble. The real speed on drivers from the TP-LINK website is 25/40 Mbps (download/upload), and on drivers from Realtek rtl8192cu (I have ver.4) - 60/70 Mbps, respectively. Torrents download at speeds up to 7.5…

  • small, works with Android TV Box
  • speed is slaughtered, drivers on home site

Return my money! Disgusting product and poor quality.

I bought it for a friend, based on the declared characteristics and price, which I already regret and it’s a shame to look into the eyes of a friend for such. Claimed: 8022022n - this is present. Max. wirelesscomnnection speed 300 Mbps - present but onlycomnnection speed.Connects at a speed of 300 Mbps, but the download / upload speed does not exceed 3.7 Mb / s. I tried to make friends with the Edimax BR-6504n, Edimax BR-6524n router, but to no avail. I removednetwork encryption - nothing has…

  • Only one - the price .
  • The speed of the reception / transmission does not correspond to the declared ones! (8022022n)

One of the best deals, glad I bought this.

I did not check with thecommputer for a long time, there were nocommments. I took it for WDTV Live (I have no plus! ) Please note that there are some problems with the plus! And do not pay (do not be afraid) attention that the whistle in WD does not light up. Everything is determined and works! I was looking for a suitable whistle for a long time. I even broke off on AsusN13 (version B1 for WDTV Live is not suitable! ) In addition to the official site, go here: there you will find a…

  • Cheap. Nice. Functionally. In other "whistles" you get confused when you close the protective cap, but here it's black and white, you can't go wrong (a trifle, but nice :))
  • Gets a little warm but works fine For me they are not

This adapter can function both as a transmitter and a receiver when it comes to Internet connections. How to accomplish it was already written about here was previously written about. I did, and there were no problems. In general, I thought it was a laptop; nevertheless, on a laptop, the G protocol is the only one that has its own adaptor. Those connections have a maximum speed of only 54 Mbps, whereas this adapter has a speed of 300 Mbps, yet they are both functioning normally. With all of…

I didn³'t expect the quality to be this good.

I needed a WiFi adapter for an older laptop that only supported the 8022022G standard, and I looked everywhere for one. I purchased and installed firewood from the manufacturer's website (it is important to mention that I have several different versions of v.4) and it all functioned properly. When the connection to the whistle was lost on the very first day, a "cold" restart of the whistle was able to fix the problem. After ten minutes, the whistle suddenly dropped its connection once more…
