How to connect two computers to the Internet at the same time with one network cable

That's all right. a. The route is set. Then add a switch to B, and B and C can both go online together.

Addendum: That's the case. If you're hands-on, that's it.

A-B is divided into 2 crystal heads, because the network cable is generally only 4, and the specific method is under Baidu. In this way, A-B can pass through the line of 2 ports. Then use one to B, and the other B is straight through to C.

And then add: I actually mean that. Two crystal heads in one line. Because generally only 4 are used. Linear. A-B used to accommodate 2 lines here. That's it.

That's right, adding a switch at point B is quite cheap. It's probably not more than 100 yuan, and I bought it for 50 yuan.

Put a router and get it, 3 on the same one is not cheaper.

In fact, it is very simple, at point A, use orange and white, orange, green and white, empty, empty, green, empty and empty to make RJ45 crystal heads, and make the rest of the blue and white, blue, brown and white, empty, empty, brown, empty and empty to make an RJ45 crystal head.

At point B, the line that also comes from point A is made of orange and white, orange, green and white, empty, empty, green, and empty to make RJ45 crystal heads, and the other two groups of blue-brown lines are directly connected to the blue-brown line of the C line, and the blue and white, blue, brown, brown, and empty lines can be made at C point.

Plug both headers into the router at point A, and both point B and C can access the Internet.

1. If both computers are laptops, you can directly find free wifi in 360 Security Guard, click to turn on, and connect to the other computer.

2. If it is a desktop, first click on the network connection in the lower right corner of the desktop, select to open the network and sharing center after opening, set up a new connection and network, click to set up a new network to re-establish the network node, set the network name and password as needed, and finally click Save, and the other desktop can connect to the network just set up through the online neighbor.

Use a network cable, one end is 568a, the other end is 568b, such a network cable can be directly connected to two computers.

To buy a string cable, and the network cable is different, the connection of the crystal head of the string cable is different, the straight line used for Internet access, and the crossover cable used for connecting to the machine!

Positive line (standard 568b): The line sequence is the same at both ends, the line sequence is: white orange, orange, white green, blue, white blue, green, white brown, brown.

Reverse line (568a): One end is the line sequence of the positive line, and the other end is: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.

Make it clear to them when you buy it, and whoever sells it will do it!

Then set the IP addresses of the two machines to the same network segment.

For example, method 1: use AB cross cable (1) to directly connect to the network cards of two computers.

Method 2: Use a common Class B cable (2), one end of each one is connected to the network card of the computer, and the other end is connected to the same router or switch.

Class B connection: white orange, orange, white blue, green, white green, blue, white brown, brown.

Class A connection: white-green, green, white-blue, orange, white-orange, blue, white-brown, brown.

That is to say, the network cable, one end is 568a, the other end is 568b, such a network cable can be directly connected to two computers.

2 computers share the wide waiting connection method.

1.Device: Broadband router.

When you buy it, tell the merchant that it is"Telecommunications"Still"Netcom", the equipment is about 100 more, and a family of four can do it.

Brands generally have"d_link"or"tp_link"

2.Connection: 1. After buying, unplug the cable that was originally connected to the computer network card, 2. Plug it into the broadband router you just bought"wan"On the mouth, 3, I am looking for a peer network cable with a crystal head, 4, one end is plugged into the network card of the computer, and one end is plugged into any port of the broadband router 1-4, so that it is connected.

5. Repeat 3-4 steps for the connection of the other unit.

3.Settings: 1. Turn on, the broadband router should also be connected to the power supply, (turn on the power of the router before turning it on).

2. Enter and press enter in the address bar of IE, the username and password are respectively"admin/123456".Note: It's best to look at the instructions because different brands of broadband routers are different.

3. The setting interface of the router pops up in IE, which is generally the same"lan"found everywhere"pop"information, fill in your username and password for surfing the Internet, and save it.
