Preface

Thank Lei Feng for giving this powerful wireless network card a chance to experience!

Why is this network card strong? Because after experiencing this product,

I was deeply impressed by its weather defying performance. Let me analyze the details.

We are not unfamiliar with wireless network cards. But there are not many people who really understand deeply.

The author has been engaged in the hardware research and development of Netcom products for many years, and has relatively in-depth research on wireless networks.

Including hardware solutions, software security and other aspects. Now, let me give you a brief introduction.

Unpacking

First, let's take a look at unpacking, The package is very textured:

Drawout design:

After opening it, I found an exquisite ball, but I have to complain that it is difficult to take out the ball. It took me a long time to pull it out:

Appearance after removal:

USB 3.0 data and power interface behind:

Matched data cable and drive CD, as well as instructions:

On the whole, the workmanship and guarantee of the products are very exquisite. The wireless network card has some weight and excellent workmanship.

Test Preparation

The wireless network card we mentioned is basically based on IEEE 802.11 standard. From 802.11a to 802.11b,

And then to 802.11g and 802.11n, the speed continues to increase. At present, it has come to the era of 802.11ac.

For the 1900M network card with high performance supporting 802.11AC, I believe that there are not many users contacted.

The DWA-192 of D-Link in this experience uses a 3x3 MIMO antenna,

What is this concept? Our ordinary mobile phones are usually 1x1 antennas,

Laptops generally have 2x2 antennas (except the latest MacBook Pro has 3x3 antennas),

More channels means higher speed and lower attenuation.

So, what's the specific performance of this network card? In order to test its performance, the author also took great pains.

After all, this network card has reached the 802.11ac, 1900M level hardware specifications,

However, the original wireless router in my home only has a peak speed of 300Mbps at 802.11n level,

It can be said that it is not suitable for Xiao Niu to pull a cart. This is why my test report took so long.

For this test, the author borrowed a three antenna 802.11ac wireless router worth 1000 yuan from the company,

In addition, SSD is specially configured for the computer and set properly to fully review its performance.

This is the reading and writing speed of the author's SSD, and I believe it can completely meet the test requirements.

Well, back to the point. First, download the Windows 10 driver from the official website:

Before installing the driver, the Win10 system cannot correctly identify the device:

After installation, the device is identified, but the icon is not native to Windows, which is not perfect:

Performance Comparison

First, let's take a rough look at the ability to search for signals. The following figure shows the nearby wireless networks that the author used to scan with other network cards and opened the airrack ng:

This is the wireless network scanned with DWA-192:

Note that the signal strength of TP-LINK_301 is only - 82dB when scanning the network with an ordinary wireless network card.

But if you use DWA-192, you can still search for two signals!

Even compared with the illegal high-power network card that exceeds the national standard, DWA-192's performance is not inferior.

As for the actual speed test, the author only has a 2x2 MIMO TP-LINK wireless network card, which is the flagship product of TP-LINK so far, supporting a transmission rate of 300 Mbps. In addition, in order to achieve a transmission rate of more than 1900M on both sides, two computers that transfer files to each other must use SSDs with a read/write speed of more than 300Mbps, and the receiver uses network cables to directly connect to the wireless router.

Compared with DWA-192, WN822N was immediately compared. Note that DWA-192 has a very small velocity attenuation with the increase of distance, which is much smaller than WN822N. As for the transmission speed, it is even worse. The speed of 280MB/s is about three times that of ordinary mechanical hard disks, and faster than most SSDs with SATA2 interfaces.

Summary

advantage:

1. Strong performance, the transmission speed of 1900M is currently the fastest among the products of Bank of China, and there is no second one

2. Price conscience, less than 400, has advantages over other products

3. The design is novel, and the workmanship and materials are thick

4. Drivers under Windows have passed WHQL certification, with stable performance and guaranteed compatibility

Disadvantages:

1. The current driver support is not perfect, for example, no Linux driver is provided

2. The Windows icon is slightly ugly. I hope it can beautify the icon in the future

At present, wireless network cards that can support 802.11ac standard and achieve 1900M transmission speed are rare. Apart from this product, BOC has no other manufacturers or brands. Only some brands, such as ASUS, have foreign models of smuggled goods that can be bought in a certain treasure. And that Asustek product is a 2x2 MIMO antenna, which is not as good as DWA-192 in long-distance performance. What's more, the price of this DWA-192 is 100 yuan cheaper than that of the ASUS parallel product. It's a price conscience and powerful performance. In a word, this wireless network card is the flagship of wireless network cards on the market. If your router and hard disk do not reach the top configuration, it can be said that you cannot even afford to serve this product. However, if your router has been upgraded to 802.11ac level, you may want to experience the proud performance of this king of wireless network cards!
