What is wireless and what is a wireless network?

After reading such a long question from you, I feel a little painful in my heart, to borrow a word nowadays, it is "cup".

What kind of laptops with permanently free Internet access advocated on TV shopping are simply playing tricks on you, playing the edge ball of the law to talk nonsense and nonsense. In fact, its so-called free wireless Internet access is with the help of wireless network card, in the case of wifi signal can be free Internet access, where is the wifi signal, now our country is only in some big cities such as: McDonald's, cafes, airports will have.

If you want to go wireless at home, you can only use wireless routing for signal coverage, so even if you can access the Internet wirelessly, but you have to pay the telecom operator, how can it be free?

Let's evaluate the 800 notebook again. An 800 notebook,The current copycat machine is small,It should be this price,It's not bad to run basic programs,But the quality is not good,Most of them must have problems within half a year。 Half a year ago, I saw a news column, which was about a **sales notebook, and the situation was similar to yours, but what consumers got from them was just a big guy that could run win95, and this kind of flickering was really heart-wrenching.

I didn't see your notebook either, so I can't tell which one you got it.

The day before yesterday, I saw a news report in CCTV, which is about a "free call" mobile phone, which is also advocating that its mobile phone can play for free, in fact, it is also with the help of network software to carry out the so-called "free call", the operation is inexplicable.

As the old saying goes, "hearing is false, seeing is believing", TV shopping and online shopping require multiple eyes.

But since you have bought it, you have to use it for it, you can use it if you can, you can type for children or something, you don't have to fall in one fell swoop, then let those profiteers be proud; When it comes to the word "profiteer", I also have to "admire" that they do everything possible to shirk after you buy it, that is, they don't push the goods to you, and there are many difficulties in protecting your rights. It is hoped that the national laws and regulations can be improved as soon as possible.

First of all, make sure that your computer has a wireless network card or 3G network card integrated with it. If you have a wireless network card: wireless Internet access requires a wireless AP.

You need to buy a wireless AP to achieve wireless Internet access - >

After plugging the access network cable into the wireless AP, you can achieve wireless Internet access within 100 meters indoors, and there is also 3G Internet access. You need to go to your mobile service provider to buy such a service and ask him to help you activate it before you can access the Internet.
