1, easy to build, difficult to build.

2. The simplest construction method

Find a room that you think is close to each room. The farthest room is less than 40 meters long and the voltage is stable, so it is designated as the computer room.

Pull a network cable from each room to the equipment room. In the rented house, there is no need to make wall boxes or modules. As long as you leave the network cable indoors, it is convenient enough to pull to the distance of each bed or table, and pinch the crystal head and put it there. The cost of the network cable is about 2 yuan a meter. You can calculate how many meters you need. Your condition must be dry. The standard length of box operation is 290 meters. . The problem is that the length of the common boxed network cable in the market is more or less discounted. . The meters are not many feet.

Buy a 24-port switch and a 16-port switch and put them in the computer room. The reason why a group of 24, a group of 16, mainly considering the expansion problem. Non-network management type fool switch, 16 port 100 yuan, 24 ports in the early 200 s.

Buy a broadband router, a better one, 100 yuan. Put it in the computer room, and the LAN port is connected to two switches.

To apply for broadband, there must be at least 2 megabytes, and it would be better if there were 4 megabytes. . Many cities don't have 4 megabytes. . You will be given a broadband cat to connect the network port of the broadband cat with the WAN port of the router.

Set the router configuration data through the computer, change the connection mode in the WAN port attribute to PPPOE, and enter the broadband account password. Do not move the LAN port properties, and start the DHCP server option.

Then plug the network cable of the rental house below into the computer and you can surf the Internet.

This is the simplest.

The problem is that if you have two computers in a room, you won't be able to use one thread. It is not a cost-effective thing to pull two or three lines for these houses.

You can prepare two or three small hubs or switches with four ports, and put one in any room with more computers for a deposit.

Solved the connectivity of the network.

However, the more people wait, the trouble will come.

Your network exit bandwidth is pitifully small, only two or four megabytes. Once a person in the local area network is downloading large files, such as movies and games, especially P2P software such as mule, BT and Thunder, as long as there is one, it will take up all your internet bandwidth. The other tenants are going to scream. . . Why are you disconnected so slowly? . . And we can't find out who did it one by one.

At this level, you can't solve it alone. . . . Need to find a network administrator or a friend with network management ability to help. . .

Also, the viruses in the network cross each other. . . . One tenant screamed and was attacked by another tenant's computer. . . . Tenants fight for network bandwidth. . . .

Also, you provide internet access, do you need money? If you want money, it's business. You must have an Internet cafe license or a network security license issued by the Municipal Public Security Bureau. . . .

Think for yourself. .

In fact, I personally think that only the rooms you manage can access the Internet. . Who wants to visit you online? Don't make such a big orchid, it is not something that a landlord can do. . It seems that every room has a network cable, and there are big things to do here. .
