Answer a user's questions about wireless Internet sharing

Wireless LAN is different from wireless Internet access. How can we achieve shared wireless Internet access through dual-host Wireless LAN? In this article, a netizen asks a question to answer the specific content of wireless Internet sharing. In short, we must distinguish wireless Internet sharing from wired Internet sharing.

Q:There are two desktop computers in the house and they are placed in two different rooms. One of them is using a wired ADSL modem to access the Internet, and the monthly fee is paid. Now the two computers need to share the internet, and do not want to drill through the wall to connect. Please provide the best solution for the selection of wireless connection methods. The total cost of additional devices is roughly the same.

Q:In addition, can the effect and speed of wireless Internet sharing be comparable to that of wired Internet sharing? Is the signal stable?

A:The second problem is that wireless Internet sharing is naturally different from wired Internet sharing. First, the speed limit of the wireless network itself makes it impossible to achieve an ideal data transmission speed of M or even m as wired. In addition, during the transmission of wireless signals, there is more or less a certain amount of loss, which also affects the Internet sharing speed. Therefore, wireless Internet sharing cannot be compared with wired Internet. We should recognize its unique advantage, that is, its maximum adaptability to the environment. It is worthwhile to sacrifice a little speed with this advantage.

On the one hand, the stability of wireless signals is affected by the quality of products, and the quality of the surrounding working environment indirectly affects the signal transmission. Therefore, when setting up a wireless network, generally, two computers with wireless connections should be guaranteed, so do not interfere with the space as much as possible. Of course, wireless connections in different rooms should be discussed separately.

Then solve the first problem. In a home wireless network, if there are only two computers, two wireless NICs can be directly connected to each other for communication. However, due to the lack of Wireless AP transit, the signal will be weak, however, the cost is relatively low. The following describes the direct connection of two wireless network cards.

This connection method is a peer-to-peer network of a wireless network card, that is, using a wireless network card + wireless network card to form a LAN. The working principle of this structure is similar to that of a wired peer network. It requires that any two sites in the network can directly exchange information. Each site is both a workstation and a server. Shows the simple topology of a wireless shared-access network.
