The front end is a router, two computers at home, a hub, how to set up a local area network?

Two machines can ping each other.

Let's come one by one.

Depending on your connection method, you can form a LAN or share printers

However, XP network problems are not ordinary, first make sure that all your computers are installed on the same installation disc, and then set up different computers with the same settings

The hub has four ports, so connect:

Take the router with four LAN ports as an example, connect the hub entrance to one of the LAN ports of the router, which will occupy a LAN port, if there is a wireless connection, then the occupied LAN port is replaced by a wireless connection, if not, then use a wire to connect back to the hub, on the line.

All the machines are set to auto IP, assigned by the router, and it's done.

You should all belong to the same LAN and should not be used for any adjustments. Build a house in Warcraft, it should be visible.

each other's. (Pay attention to the settings of the firewall).

There should be a switch in your dorm building.

If you only use the LAN, you can use the router, so your computers are connected to the hub, and if you all have your own hub, connect the 2 hub network cables.

The premise is that it is best to manually assign IP to each computer; Gateway, the gateway must be consistent, such as or.

Yes, one hub is enough, one end of a network cable is connected to the total interface of the network cable, and the other end is connected to the hub, and each computer is connected to the hub Each computer is configured with the IP address and subnet mask — 6 computers Subnet mask Fill in these 2 items If the hub port does not have 6, use a wire from the hub to the router to OK.

If you want to build a LAN at home, it is recommended that you use a small router, which has many brands such as TP-link. Why choose a router, because of convenience, he supports ADSL, that is, PPPOE dialing, the average family ADSL, and now mobile phones, tablets and everything have to be wireless, so buying a wireless router is the way to choose.

It's OK to get it automatically from each computer, and for people who are not very strong in computer technology, don't use the specified IP address, it's a little troublesome to match. And if it's a laptop, you may not be able to use the internet if you forget to change it back to another place.

So with all that said, what I said you can consider.

Of course, the number of computers is small, and the computer room or Internet café only uses switches, and the hub has long been eliminated. Don't worry about the IP settings, these use the default will do.

Your cat doesn't have a routing function, and now that hubs are eliminated, it's better to use a switch than a hub.

However, a hub for just two computers is fine.

It is possible to set up a small LAN alone, just connect two computers to the hub, but you can't connect to the external network, because there is no route, to connect to the external network, your cat must have a routing function, or connect a router on the cat, or change to a cat with a routing function.

Your hub doesn't work, your cat doesn't have a route, you can do dual NICs, one of the machines has two NICs. A network card is connected to the Internet, another network card, and another machine networking, a network cable is a normal practice, and another is the right line sequence. But every time you go online, the machine with two network cards has to be turned on, or the other bar can't get on the Internet.

The other way is to buy a router, or an ADSL cat with a route.

The star distribution method is the most scientific, and the vast majority of the current network structure adopts the type wiring method, that is, a hub is inserted from each of the three LAN ports of the route, which is commonly used, and the transmission of data is also more stable, and the loss will be less, because the hub will filter out the network storm when passing through the route.

As for network storms, in the LAN composed of hubs, at most one device can be in the sending state at any one time. When device A wants to communicate with device B, it is to"Broadcast"It is sent to the whole network, which means that it can be recognized as its own after receiving it, so that it can be processed, and at other times two devices are sending messages, it will generate one"Conflicts"As a result, both devices cancel the send and automatically delay it for a period of time before retesting, which means that shared Ethernet networks cannot be combined into a large network, which typically does not exceed 10 connected devices.

If you replace the hub with a switch, the situation is different. The switch recognizes that the message from device A is sent to device B, so it only allows A to communicate with B. Instead of broadcasting to the entire network.

Therefore, while A communicates with B, C and D can also communicate. This significantly reduces conflicts"The probability of improving the utilization of bandwidth, so now more and more networks are being formed"Switched Ethernet"

So it is recommended that you replace the hub with a switch, there will be no problem inside, as for the problem of cracking the wireless receiving network card you said, it is too ruthless, because you are alone and others will feel it when they are on the Internet normally, if you suddenly add 3-4 units, it will cry...

Let's think about it slowly, I thought about it, and let me know 1 when I announce it

If you want to use it.

Hubs are connected.

The internet needs another one.

The router device, ** line is connected to the router first, set up to use the router to surf the Internet, and then route it on the hub. The hub passes through again.

A network cable is connected to the computer. If other computers want to connect to.

In the local area network, you can connect to the hub through the network cable. If you want to do this, you can contact me.

If the cat has a routing function, just connect it directly to the settings, otherwise you have to use a router, you can connect to the hub after the router, use your username and password, set up the router on the line, buy the shopkeeper can set it up, and you can set it step by step with the manual.

...Plug it in.

The IP address is set to the ratio of the network segment.

Set up each machine.

Firewalls (including anti-virus software.

Off) should be implemented to say shared.

Play online.

Line a certain machine. Create a workgroup for its own machine.

Joining is to create a net.

Neighbors know.

I recommend using, routers. Because if the router is not turned off, it will not affect any computer.

Hub if the master is turned off. The other computer can't access the Internet.

Specifically buy a router, there will be instructions above。。。

Hello! Both of your devices only have 4 LAN ports, right?

According to the situation you described, the easiest and most reasonable way is to use the router as a hub (be careful to turn off the router's DHCP service).

The campus network is connected to a hub, one port of the hub is connected to a LAN port of the router, three computers are connected to the hub, and two computers are connected to the router.

Since you're all dial-up networks, I'm afraid you won't need a local connection. If you still want to do some LAN file sharing and LAN battles when you are not surfing the Internet, you can set a static IP in the local connection attributes, pay attention to the IP address and the network segment do not repeat, and then ensure a unified working group. In addition, the firewall settings should be set up at the correct level.

You don't need to set the gateway, you can directly set the IP segment of the Class C network. For example, the network segment. However, it is important to note that when connecting to a local LAN, do not use your account to access the Internet.

1. In this case, the router can only be used as a switch.

Second, you can connect like this:

1. The school's network cable is connected to the LAN port of the router.

2. Wiring from the router LAN port to the hub.

3. The computer can be connected to the hub, or it can be connected to the remaining LAN port.

4. This will not affect your LAN access (of course, the IP of each computer should be the same IP segment).

It is best to use a switch, if the socket is used up, then use the hub for subordinate division, the school's line is connected to the WAN interface, the other interfaces are connected to the computer, and an interface is left to connect to the hub, and then tap to the computer.

It's so troublesome to get an 8-port route, what do you do with the hub, the school network cable enters the WAN port, the routing configuration automatically assigns IP, and the network connection does not set dialing, which is o.

Yes, you can use the router as a hub.

It's almost the same at home, but the router has an automatic dialing function. Several machines at home are connected as long as they are set up, and you can access the Internet as soon as you turn on the machine.
