My Thinkpad laptop wireless network card is intel 6205, wireless connection speed is only up to 300M, when the file transfer with the desktop at home is very slow, only about 20M/S, if more than 4GB of video files, It is unbearable. So plan to buy a good USB wireless network card for home use. So whether there is any suitable tea on the East, my key words are: USB, Gigabit, wireless network card, find a lot, choose to pick the rest of these:
Will be level: these four are 1200Mbps, three hundred three or four wire products, plus a first-line TP-Link, of course, the actual 5G speed is 867Mbps, plus 2.4G 300Mbps It is barely 1200Mbps, but it is pseudo-gigabit.

TP-LINK TL-WDN6200 1200M Gigabit High Speed ​​Dual Band Wireless Networking Card USB Desktop Notebook Portable WiFi Receiver 165 Yuan Jingdong Direct Link Preferred level: My router is a netware R7000, AC1900 dual-band, so the 1900Mbps wireless network card is the first choice. There is not much room for this choice. After removing the expensive Asus and Netware, I only look at these two. 5G itself has reached 1300Mbps, and 2.4G has reached 600Mbps. This actually satisfies my needs.

Orders were received at night and received the next day. Dog delivery was one of the reasons I supported him.
There is a driver CD, but I don't have a CD-ROM. I can only download it from the official website: official website TP-LINK TL-WDN6200
This speed must use USB3.0, before looking at the comments to see someone say that a USB3.0 wireless network card USB extension cable is actually USB2.0, we have to pay special attention when buying.
QSS quick set, I temporarily use this
Compared with the Sandisk CZ80, it's still a bit big.
Can not wait to use the computer to try it, the router is linked to the company's Asus AC88U, than some of my family to cattle, there should be no bottleneck. The contrast is the intel 6205 300M wireless network card.
TP bundled management software when installing the driver, of course, can also choose not to install, never used, or installed a try. Link ASUS AC88U, speed display 867Mbps, full speed. The signal strength is very good. The router and me are separated by a brick wall. The straight line is about 3 meters. This 5G wall can also be ah.
Check the windows network, which is another wireless router that is linked. The R6220 is a 1200M router.
Let's take a look at how the two wireless network cards look for the strength of the wireless signal. At this time, we can see that the intel 6205 identification signal is stronger than the TP 6200. The Asus 2.4G and 5G have the -32 (the closer to 0 the better). TP recognition is a bit worse, 5G is -35, and 2.4G is -60, another router Adai-400 is separated by 2 walls, the straight line is about 6-7 meters away, TP identification is -80, and intel is -60, there is still a little difference. But in the end it still depends on the speed.
Between my desktop and laptop, the ASUS AC88U links, but the network transmission speed is only 81.5MB/S (it should be more than 100M/S transmission speed.) I do not know the specific reasons.
The TP's 867Mbps average transmission speed is 54.7MB/s, which is basically only half of the theoretical value.
The average transmission speed of the intel 300M wireless network is 24MB/S, and only half of the TP is not.
In summary, the network transmission speed of this TP-Link TL-WDN6200 makes me reluctant to accept, if can reach 70-80M/S, then that can, do not know 1900M wireless network card can reach this speed, but all To 200 or more oceans, a little expensive.
Note: During the day during the day, the students said that the laptop's wireless network card, the second floor of the search less than the first floor of the router signal, let me give him a wireless network card, find the Internet to find a white list, more tossing, so ask him outside USB network card can not be set, is it convenient, he said yes, so took me this last night, called at 11 pm when the signal can be found on the first floor, with a no problem, then Say this card is with his surname, let me buy another one. A little tangled, do not buy the above two 1900M, Baidu did not find these two evaluations.
Did you use any of these two friends?
