HUAWEI EC1261 is a classic CDMA-EVDO network card, which is equally satisfactory in practical applications, both at average speed and at maximum speed. And its stability is also quite excellent, which can ensure stable operation for a long time. The support of multiple operating systems allows users to purchase with confidence, which is very convenient.

As a network card, of course, the user is most concerned about the speed of the card, the author has done some simple tests on the Internet speed of this product at home, which uses the right click to save as the way **The speed is stable at about 70kb s, and the performance is still very good. The use of Thunder** can fully reflect the network advantages of EVDO. In the stationary state, the peak speed of the data card can reach 190kb s, and the average speed has reached more than 120kb s, which is significantly better than the ordinary 1MB ADSL broadband connection, and the model is very stable during the whole test process, and it is not affected by the signal shielding in the indoor environment.

3G Wi-Fi Internet access is okay now! **Speed more than 100K, pay attention to where to use when buying, browse the web, use traffic on QQ, if you want**, watch a movie to find a timing card!

Whether the wireless network card is easy to use or not depends on its quality and quality, generally speaking, the high quality is better, the low quality is worse, and there is his capacity problem.

1.If you can install ordinary broadband, it is not recommended to use wireless network card business, whether in terms of cost performance or stability, wireless network card and ordinary broadband compared with a considerable gap, although the limit speed may be higher than broadband, but there will be a lot of restrictions on traffic or time, and the cost is quite high after exceeding.

2.In terms of 3G wireless network cards, China Unicom has the best speed, followed by Telecom, and the mobile speed is the worst; In terms of 3G network coverage and stability, China Telecom is the best, followed by China Unicom, and China Mobile is the worst. It can be said that if you have been using it in the same big city center, it is recommended to use Unicom, because the speed is the best, if you often travel or between large cities and small cities, or even need to use it in rural areas, then telecommunications are preferred; As for the moving ones, don't think about them;

3.In terms of tariffs, because of regional and economic differences, they must be different, and different operators are also different, and the same operator also has different tariffs**, so you still directly consult the operator's customer service to understand;

4.In terms of wireless network card equipment, Huawei is currently doing the best, followed by ZTE, ** is generally about 200 yuan, it is recommended that you choose these two brands of wireless network card products, with good stability and good use effect.

The function of the wireless network card is to connect to the local area network. It is only a signal sending and receiving device, and the connection to the Internet can only be realized when the exit to the Internet is found, and all wireless network cards can only be limited to the range of the wireless LAN that has been deployed. A wireless network card is a network card that is not connected through wired connections and uses wireless signals to connect.

The steps below are to check if your computer has a wireless network card.

1. Turn on Windows 10 system. Right-click on "This PC" on the desktop and click on the "Manage" option.

2. Click "Device Manager" in Computer Management and click to open.

3. Finally, you can see the installation of the wireless network card in the window, and the problem is solved.

Wireless network card is a terminal wireless network device, which is a wireless terminal device used for Internet access through wireless connection network under the wireless coverage of wireless LAN. Specifically, the wireless network card is a device that enables your computer to use wireless Internet access, but with a wireless network card, you also need a wireless network that can be connected, if there is a wireless router or wireless AP coverage at home or location, you can connect to the wireless network through the wireless network card to connect to the Internet in a wireless way. The device of the wireless network card is shown in the image.

The wireless network card services of major companies should be said to be good and bad.

2G wireless network card, the network speed is too slow, 1-5kb s, the fastest time is only 10kb s! If you buy a 3G network card, it's almost fine, but it may be expensive. I have a book, I bought a wireless network card in January this year, when I bought it, I basically went around all the sales points in the city, I inquired, the mobile 3G network card, about 720 yuan, with equipment, there is a traffic limit, 15G traffic per month, this traffic limit is not calculated by day or hour, it is a month to give you 15G traffic, run out of pull, can be used for a year and a half; Telecom's 3G network card, about 900 more, fast to 1000, with equipment, no traffic limit, can be used for one year.

I am now using Telecom's 2G network card, ** is 560 yuan, with equipment, no traffic limit, can be used for one year, the network speed is very slow. However, my original consideration was that I was only using the Internet to get on QQ and browse the web, and there was no need for a 3G network card. And now the 3G network card is still a new thing, and after a year, ** will almost come down, and then buy a 3G network card!

In addition, now Unicom and Telecom have merged.

And now I've heard that the 3G network card **seems to be again**!

Of course, the 2G wireless network card can't catch up with the wired network speed, and the 3G can be compared!

It is recommended that if the economic conditions allow, you can buy a 3G network card, if not, you can buy a 2G to play, it is better to pull a wired!
