3 computers go online, use routing, why do you pull out the No. 2 network cable, and the No. 1 machi

You didn't set it right, set up the account number and password in the router, enable automatic dialing, and as long as you turn on the router power in the future, it will automatically dial up, and you don't need to dial up again for 3 computers!

The IP address of the local connection of the three computers should be set to the same network segment as the router, for example, the router is, and the three computers can be set to ,,; Subnet masks are; (It's best to look at the router's manual, pay attention to the router's default IP, username, and password).

XP system, on the right side of the network connection window there is an item "Set up a home or small office network", click it, click "Next" twice, then select the second item, click "Next", take a name at will, and keep "Next" until completion, then restart the computer, OK

Is there a limit to your local network operator?

I don't know if you're a **person

Given that you give too few points, I can't type too much

You first connect the cat to the No. 1 machine, and then connect the No. 1 machine to the first port of the router, and the No. 2 and third machines to the second and third ports, and you can divide the IP.

Quietly come to ......Walk quietly ......

It's okay to set it up in the router.,According to what you say, you don't use the route at all.,Enter or the username and password are admin in IE.

The following possibilities:

1.The third laptop has been set up with IP and DNS, but it is not the same as the intranet settings you are currently using.

2.The DHCP of the route is not enabled, and the third notebook cannot obtain the IP.

Log in to the router to update, update the MAC address of the third computer such as the router, or restart the router to connect.

Set the third laptop to automatically get the IP and you're good to go.

To summarize the various reasons, it is the IP address that is set incorrectly. Check the IP of the third laptop to see if it is the same as the previous two.

You can put your router model, or take a picture of the back port** to take a look.

1.Your router is only wired, and there are two types of ports for the small router bought in the computer city: one is the WLAN port, and the other is the fast ethernet (ordinary switching port).

2.The router you bought was bought for several ports. If you want to access the Internet, the port plugged in can only be a switching port, not a routing port.

3.In general, the computer and the exchange port are connected with a straight cable. However, the adaptive function of the computer network card is now available, and some cross-wires are also available, but it is best to go through the line.

Finally, I met you in this situation.

It turned out that I was a network maintenance worker at a four-star nine o'clock, and found that a floor switch was 16 ports, but there was also an up-link port (in fact, this port was shared with the 16th port adjacent to it), if the 16 ports and it were plugged in, the whole network would be disconnected. You're in a similar situation.

Set the IP address of the third device to automatic. Right-click on the Internet Neighbor - Properties - Right-click on the Local Connection - Properties - Double-click on the Internet Protocol in 'This link uses the following items' under the dot 'Get IP Address Automatically, and Automatically Get DNS Server Address - OK.

Try to change the ADSL shunt, if you can use it after the change, it is the problem of the shunt......You can borrow someone else's ...... and try it

Could it be that the network provider does not allow the use of the router, or your router is set up incorrectly.

Here's a suggestion for general router settings:

Connection: (refer to the router manual).

The final network cable of the network ** provider is plugged into the WAN end of the router (no network cable is plugged in when set), and the network cable of all computers is plugged into the LAN end of the router.

Settings: (refer to the router manual).

1.Remember the settings of the business to you, and if you can't remember it, you can ask them; Use these parameters to set the WAN side of the router.

2.Set the LAN side of the router: Enable DHCP service3

Check whether the gateway address of the final network cable plugged into the computer is the same as your wireless router address, if it is the same, please change your router address, for example, you can change yours.

4.Set all Internet devices to get addresses automatically.

That's pretty much it, remember: the WAN setup method is determined by the network cable plugged into the WAN side.

Thank you for your question.
