Can one network cable and switch access two computers?

The broadband network cable of the telecom is directly connected to the switch (if it is ADSL, it is also the same to connect the modem to the switch), and the host IP setting method for dial-up Internet access first: see the local connection in the network connection, click on the right health selection properties, and click the Internet Protocol (ICP IP) attribute before the icon in the notification area after the connection, and click to use the following IP address: IP address to fill in:

Subnet Mask:, Default Gateway:, Preferred DNS Server:

Point OK. Then establish an ADSL connection on this machine, and then click on the ADSL connection to select the attribute Advanced: will allow other network users to connect through the Internet connection of this computer.

Other machines also use the right health point local connection attribute in the network connection, except for the first IP address to fill in: the latter number is filled in except 1 2 255 which number is OK), the rest is the same as the first machine.

In this way, the first to establish a connection enters the account password to connect to the Internet, and after dialing in to connect, the other machines will naturally connect.

Other machines can also be the host, other machines to be the host also establish the same dial-up account and password on the line, in fact, there is no need to set up each one like this, with one or two management personnel with the machine to set up this way, just say that this method can work, in addition to these connected computers in the LAN are set up with a solid IP, but also easy to manage).

This method only uses a switch instead of a router to share the Internet, does not use a server, and only needs a network card on the host used for dial-up, and there is no need to add another network card or anything, which is simple and convenient.

You can add a network card to your machine, and then use a PC-PC cable network to connect the two computers to share the network. Return.

PC-PC reverse line.

Route-PC positive.

Switch A-PC positive.

Route-Switch Positive.

Reverse line: also known as cross line, according to the standard of 568b at one end and 568a at one end, arrange the line sequence and clamp it.

The specific line sequence production method is: one end uses 568b to do the line standard unchanged, and the other end will swap the positions of the 1,3 lines and 2,6 lines in the eight lines on this basis, and then the line sequence of the network cable becomes: 1, white green, 2, green, 3, white orange, 4, blue, 5, white blue, 6, orange, 7, white brown, 8, brown.

This is the 568A standard of 100m network cable, which is what we usually call a reverse line or cross line.

The positive line is the 568B standard line used on both sides, also known as the straight line, the positive line.

568B standard: 1, white orange, 2, orange, 3, white green, 4, blue, 5, white blue, 6, green, 7, white brown, 8, brown.

One broadband, one network cable, no need to switch to connect two computers. Here's how to fix it:

1. If you want two computers to access the Internet with the same rights, you must have two computers that can communicate, and one of them provides ** Internet access as a connection broadband.

2. Install dual network cards on the host computer connected to broadband, one network card is connected to broadband, and one network card is connected to another computer.

3. The computer connected to broadband accesses the Internet through PPPoE dial-up and shares the network card connected to another computer.

According to you, no. copy

The easiest way to share two units is to pair them, which is a little more cumbersome to set up.

First, you need to make another crossover line of a two-machine couplet.

Second, you need to install an additional network card on your machine, that is, dual network cards, one in and one to connect to the other.

Then set up dual-device sharing.

Remember, it's a two-machine connection line, a cross line, and a network cable seller to say that he will know.

Suggestion, don't do that, the cost is about 20 yuan. If you buy a switch, it will be about 40-50 yuan. If you just use it for a while and it won't last for a long time, then it is recommended that you take turns using it.

The method of connecting the network cable you mentioned is definitely not good.

The first set of plans: The computer city has the kind of one-and-a-half crystal head back joint, you can try to answer, maybe a few dollars.

The second set of solutions: install two network cards on a computer, make a bridge, and then transfer the third set of solutions through the bridge: buy a router or switch, it is only a few dozen.

What you're saying is that you don't want to buy a device, and you can go online directly for two people, which is actually very troublesome. You don't need a switch at home, you only need a router.

If you don't use a router, two computers want to go online, it's really troublesome, condition 1, two computers need to be turned on at the same time to access the Internet, condition 2, there must be two network cards. It is a dual network card to share broadband, although the method is OK, but it is not recommended to use, because it is really not a good solution.

It is recommended that you buy a 4-port router, and the D-Link one will cost 85 yuan. Convenient and hassle-free. The specific instructions for setting up the router are all on the manual, and it is very simple.

There are two sides.

Copying the first simple buy a road.

Bai by the second du

The first is to get a gateway in one of the machines to add an additional Ethernet card to the dao side and then connect the two computers together The host goes to the network connection settings Small home office network selection This one is the host and the other one also goes to set up Choose to log in through the gateway and just do it I used to do it Later I felt troublesome because the host must be turned on.

May I ask the landlord of my home broadband 2m, today my brother brought back a network cable, want to access the Internet without buying a computer, and then use my computer for two.

Buy another network card.

The implementation of dual network cards can be done. But it's better to buy a road.

By the device (4 mouths), it is 70-90 yuan. Buying a switch back can not realize the answer to two Internet access, the switch and the router are not the same. The function of the router is routing, that is, virtual dialing, and the function of the switch is to divide a network cable into several network cables through the switch, and connect to other computers to access the Internet together; If you don't have a router, it's useless for you to connect directly to the switch, and you can't connect to the Internet.

Khan: You should be an optical fiber TV.

You can connect two computers to the local network, and if you want to connect to the Internet, you need at least a router.

Otherwise, there are so many jacks.

A broadband requires a router if you need to access the Internet on multiple computers (if you use it.

The switch machine is connected, and there must be an electric power brain with two network cards), otherwise only one computer can access the Internet. Cut off your network cable, and he can access the Internet after he is connected. If you use it for a long time, it is recommended to buy a router. The market price is around 100 yuan.

No, you can't branch the network cable no matter what. If you don't use a switch, you can only install two network cards on one of the computers, and share the network with the same computer with two network cards.

It's hard, buy a route! With the switch function, it is only about 90 yuan to buy TP-link402

You can use Shuge for this**.

Yes, one machine needs two network cards, another network card, one of the connecting lines is a non-standard line, you can go through the dual network card machine transfer, let the other machine go online, this is the original router is very expensive when the method used.

The current connection method, a router, is responsible for dial-up Internet access and distribution connection, only need ordinary four ports, you can connect four computers by wire, if it is wireless, use wireless connection, you can connect 254 computers. If you have a wired connection, you can also connect 254 computers as long as you buy a cheaper hub and expand it layer by layer.

It is recommended to buy a wireless router, which also comes with four wired sockets, which can be wired and wirelessly connected, and when the wireless is not needed, it can be turned off, and the setting method is to see the disc that comes with the device.

1. The network cable tee (i.e. a two-way adapter) can not be used at the same time to connect to two computers, the network cable is point-to-point, if there are two or three network devices sent and received at the same time, the signal will be chaotic, and it cannot be used at all.

2. This kind of tee is one in and two out, and only one can be used when it comes out, and two cannot be used at the same time. This tee is actually used for splitting lines, such as connecting the ** line to the position of the 7 and 8 lines that are not used on a network line, and then using the tee to separate two ** wires to use.

3. If there is only one network incoming line, you only need to add a small switch to solve it. Here's how to connect:

Are you talking about switches? If yes! Both computers have internet access! But not both! Only one can be on, that is! A can't go online and B can't get on! B can't get on A, and you have to use a router if you want to get on it at the same time

Why don't you connect directly to the router with two network cables?

A split in two fitting is theoretically unusable.

Because every computer has to have an IP address.

So one port with two IPs, that's unreasonable.

[Router] has N outputs, and can be directly connected to N host network cards through data cables without having to split two adapters.

There are four pairs of wires in the network cable, and the 100 Gigabit network only needs two pairs of wires to use, and theoretically a network cable can bring two computers through four pairs of wires (two pairs each) in the case of a 100 Gigabit network.

Just spend 80 yuan to buy a 4-port router.

The general adapter is not good (about 2 yuan), it can be raised to the hub set or switch, and the two-point adapter is mainly used for testing between two different networks.

The identification of computers and computers, as well as other devices, is identified in the form of MAC addresses.

Even the switch still has a MAC address, which means that a group of network cables can only have the same MAC address. The method you are talking about. Only one computer can access the Internet properly.

As for:"Some do not need to prevent network mergers"I really don't know what to do.

Neither theory nor practice is possible, because the switch has to assign an IP to each port

Theoretically, yes.

One split is equivalent to an ordinary switch.

At that time, it was necessary to pay attention to the way of surfing the Internet, if there was dial-up Internet access, it was not possible for the ISP to do port ARP

No, the network cable must be a 1236 line to access the Internet.

The other 45 78 is used as ** line.

The IP addresses of two computers under the same switch must be different, otherwise a message will prompt a conflicting IP address. For example, if one of them has an IP address, the other is.

IP address refers to Internet Protocol address, which is the abbreviation of IP address. IP address is a unified address format provided by the IP protocol, which assigns a logical address to every network and each host on the Internet to mask the difference in physical addresses.

By doing NAT, multiple computers can share the Internet, but in general, there is only one public IP. However, you can set different private IPs on your computer and go to the public IP through nat**.

If two computers have the same IP set, it will cause an IP conflict!

Hello! May I ask if you are talking about a network cable access, connected to a switch, and then connected to two computers under the switch, can you put the IP of the two computers (is it a private IP, or a public IP). For example:

Generally, the same public IP environment can not enter the same QQ bucket landlord's anti-cheat room at the same time) becomes different?

Answer: No!

Yes, you just need to find a >v< >p< n** (just those three letters.) )

He can take all the IPs of your whole machine out**. This way your machine IP will be different.

Yes, use a router or switch, a router is recommended.

You can manually set the LAN IP address of each terminal, but it can only be done in the LAN segment, otherwise it will not be available if it is set; However, the public IP addresses of these terminals are the same.

If you want to access the Internet, you need to connect to the router first, and then use the switch for extension (if the incoming line is plugged into the computer, you can directly access the Internet to the switch, and manually set the IP address, gateway, DNS) One network cable enters the WAN port, and two are connected to the host from the LAN port.

In this case, you need to connect the router first, and then use the switch to extend, it is recommended that the router be set to automatically distribute traffic, one network cable enters the WAN port, and two network cables enter the host from the LAN port for connection.

It was an 8-core network cable.

Directly connected to the switch.

Then prepare 2 network cables to connect the interface of the switch and it's OK, no need to set anything!
