About ADSL and 2 computers

If not, buy a router, connect the router to the port, and then connect the rest of the machines to the router, use any machine as the host, log in the network card, and then assign IP to all the machines, the specific operation is, select the local connection - > properties - > internert protocol. In fact, the router is a small gateway, and its IP is the default (, the host is set.

The rest of the machines are randomly set from to, and the next time it starts, which machine starts first, is the host. Haha, it's all done, it's a lot of fun!

Supplement: If you want to increase the number of computers in the future, you can buy a hub or switch to connect to the router to increase the number of ports.

Using a router may have some impact on the speed of the network, but in theory it is not very significant, and if there are special circumstances, you will have to consider other options.

Good luck, friend!

Just use the router. Nowadays, ADSL cats basically have routing functions. Set up autodialing on the cat. You can access the Internet wherever you want.

Your cat comes with a route, just go directly into the cat and set it to the routing mode!

If the cat doesn't come with its own route, you can buy a router!

Oh, it's solved with a router... My two are like this, let the router go online and buy one, about 100 yuan, and the seller will tell you how to use it.

Use a router to split the network cable out of the demodulator into two, but the Internet access at the same time will be half as slow.

Just buy a router and divide it into two machines!

If you don't say it, you must choose a router.

The router can broadcast the number, and it can be automatically broadcast when it is powered on, so you don't need to broadcast it in the computer, and you can go online directly when you turn it on. The hub can't, it just has the ability to connect several machines in series. And with the hub, there will definitely be a situation in your problem supplement.

Unless your broadband cat has a routing function, but I don't think telecom will give you such a cat).

The routing data exchange is bidirectional, and the hub is unidirectional. (Routing is faster than hub) routing has the function of broadcasting, but hub does not.

The router is like a host, as long as it is on, other machines can access the Internet at will, and there is nothing to do with each other.

The hub must have one host, and all the hosts will be dropped as soon as they fall. If the host is not opened, no one should think about it.

Hub don't talk about it (something that no one uses anymore.) Even if you use a switch), the power supply will be plugged in, right? Hehe. It turned out to be on the Internet. Broadband cats, that's not to say.

Connect the cable you used to have from the cat to the computer to the designated port on the router. Let's pick it up from another port to the computer. (After you buy the router, there is a manual in it, and you can do everything at a glance, it's very simple).

What you should pay attention to is the network cable, and when you go to the merchant to make the network cable, you must explain what you want to connect.

The connection route that can be used by the hub may not be usable. You don't need to understand this, and you don't make network cables every day. Just let the merchant get it. Who would buy a network cable pliers at home and not use it once in a hundred years. (Hehe, no, my network cable is done with teeth).

Use the route without opening a computer to broadcast the number, after setting it up, there is no computer, as long as the route is turned on, it will also broadcast the number and wait for your computer to surf the Internet (hehe, convenient).In the computer, you only need to change the IP address, *** and the route is one to) nothing else. Oh yes, the IP addresses of the two computers can't be the same.

And the name can't be the same.

It is mainly set in the route, and the general route will have a setup wizard. Just follow the guide step by step, it's very simple. At a level where you can ask these questions, I believe you can understand them at a glance.

There are two ways to connect more than two computers, one is to use a routing cat and a switch or hub. Take Huawei cat as an example, "because the IP address segment and account name password of different cats are also the same (such as, etc.), you can read the manual or check the Internet" first set your computer IP address to between, the gateway is, DNS can call the operator ** to ask (Netcom 10060, Telecom 10000, Tietong 10050) and then enter the address bar to make sure that the account name and password are admin can enter the setting, vpi VCI value varies from place to place, such as 0 35, etc., you can call the operator ** to ask, The encapsulation mode is LLC, and the protocol setting is pppover

Ethernet Password Protocol: PAP username and password are the names and passwords for your broadband Internet access.

Note: The computer does not create PPOE dialing. The second way is to buy a router and set it up in the same way as above.

For the answer to your additional question: Yes, there is no need to open the host and there is no distinction between primary and secondary computers, and each computer is equal.

Let's go buy another route. First of all, connect the ** cable to the voice splitter, there is one end of the mouth, and there are two ports, one end of the phone on it**, and a section of the modem is terminated to the cat. Connect the cat with the WAN port of the router with a network cable, and connect the LAN port to the computer, so that the computer can automatically obtain the IP, and there are settings in the network connection.

There is a login route, password, and address route on the back. Landing routes. Establish a connection, use PPPOE dial-up, enter the password given to you by Telecom, confirm, and save it.

Yes, you don't need to **, just set one of them as a server. In fact, it is very simple, connect two computers to the switch at the same time, and connect the ADSL Internet cat to the switch, that is, the switch should be connected to three devices [two computers, one cat], the following picture: In this case, when machine A dials up the Internet, machine B can directly access the Internet, and you can also set machine B as a server, in this way, it is to use a computer as a server to access the Internet at the same time, if only one machine is turned on, then you can dial up the Internet normally, [There is also a sequence problem, If the server is turned on first, dial-up to the Internet, the two machines can be used at the same time, if the client first dials up the Internet, it can only be used by the client, the server can not access the Internet at the same time, must disconnect the link state of the client, dial-up with the server, can access the Internet at the same time]; It's too verbose.,I don't know if I can understand.,In fact, the most convenient way to share the Internet is to use a router.,It has nothing to do with the computer.,It's the same as the Internet café.,Two machines and that can do.。

The picture is not very clear, let's explain it:

Hehe. Cat The middle of the right is the switch, the far right is the comment, the above is for machine A, if it is set as a server, first fill in the IP subnet mask Gateway DNS It is best to set the IP of the server and the gateway to the same value as the server if you use that computer. Except for the last value of the IP address, all the other values of the computer must be exactly the same as the computer that is the server.

For example: a computer network card parameter [do server]:

IP Subnet Mask:

Gateway: dns: can also be left unspecified).

b. Computer network card parameter [client].

IP Any value )

Subnet Mask: Gateway: DNS: You can also leave it unspecified).

Probably not, because you're more than one machine, and the ISP will only assign you one IP address, and it's dynamic. So there's a question of NAT here.

If you have to use an ADSL to connect to an SW and then connect two PCs, then one account for each PC should be fine. I used to be like this with my classmates at school, and at that time, the Internet was charged by the hour (the school was black), so we each counted our own money, and no one owed anyone.

NAT is a routing function, and as far as I can see, I haven't seen a switch with NAT function.

About NAT:

The other thing is the soft routing that I said upstairs, but I personally don't like it, after all, it's a software form of routing based on a PC. It feels unstable and a bit of a hassle, not flexible for a PC.

Yes, the next ** software is OK, and there are a lot of searches on the Internet.
