Can two computers go online without a router?

No, you can't use 2 cats, one cat, one ip, you can only use routers, I hope mine will help you.

No. A broadband router (SOHO) is required.

Establish an ADSL connection to the network card of the dot modem, and then the shared IP will be changed to another network card IP instead.

The IP of the network card of the computer that shares the Internet access is set to Gateway is set to.

Network card B and the network card of the shared computer are connected with a network cable.

The connecting network cable needs to be specially made.

The use of parallel lines is that we usually use parallel lines, and the practice of parallel lines is to use the same standard at both ends (both 568a or 568b).

The practice of connecting the network card to the network card with a cross line is: one end adopts the 568A standard, and the other end adopts the 568B standard.

Ordinary network cables are divided into two kinds, one is machine-to-machine, and the other is machine-to-hub, which is both the same equipment and the other is different equipment. First, there are two crystal heads for network cables, and different network cables have different practices for crystal heads.

There are two common methods of crystal heads, one is 568a, one is 568b, and the crystal head of the same equipment is composed of two crystal heads, one 568a and one 568b. The different devices consist of one or two 568A or 568B heads.

Here are two ways to wire the crystal head:

568a: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown-white.

568b: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown-white.

When connected to the gigabit network, it is slightly different: one end is: white orange, orange, white green, blue, white blue, green, white brown, brown; The other end is: white-green, green, white-orange, white-brown, brown, orange, blue, white-blue.

The router is set up with wifi, one computer is connected to the network cable and set as the host, and the other computer only needs to be connected to this wireless.

The network cable must be redone, and the two machines use a crossover line (one end is a connection, and the other end is a B connection).

After making the network cable, you can connect to the phone.

For example, machine 1 is equipped with 2 network cards, network card A is used to dial up the kitten, and card B is used to connect to machine 2.

Establish a broadband link (if you have it, you don't need to build it), share the broadband link with the Internet to the B card, and after the No. 1 machine dials up, the No. 2 machine can access the Internet (the No. 2 machine does not use manual IP designation).
