The problem of sharing the Internet, the solution to the problem of sharing the Internet cannot be a

You can buy a switch, and the eight-port one is about 80 yuan.

Plug the network cable from the cat into the switch, and then connect the network cable from the switch to the computer.

I don't know if you have a monthly subscription or a card to access the Internet. If it's a monthly subscription, the above method can be directly on, if it's a card, everyone can buy a card on the client. If you want to save money, you can buy a card alone, and then install a shared Internet software Sygate, which can be downloaded online.

Just buy a switch. Or a hub. Both the cat and both computers are connected to the switch. You're still dialing the same number. Then share the connection.

If you don't have more than three computers. It's best to buy a router. If there are too many computers. No way. If you can log on to QQ, you may not be able to go to the website.

The cat is followed by a router. The route is followed by a computer.

But it's best to find out if Netcom is route-restricted.

If it is limited, prepare a cracking method at the same time. It's okay to ask someone else's dormitory for advice.

The network used in the school's offices and laboratories is a shared campus network, and in the dormitory, it is common for several people to open broadband for one account and then share it with several people. Not to mention the fact that broadband itself is not allowed to be shared, computers that share the network often cannot access the Internet due to IP conflicts. Let me introduce you to a way to solve this problem, you don't need to install any additional software, just a few steps.

The solution to the problem that the shared network cannot access the Internet

Find the local connection (because it is a shared network, it is a local connection instead of a broadband connection), double-click the dialog box shown in **, and click "Properties" in the red circle.

<> the Internet Protocol version attribute pops up, circle the boxes in front of "Automatically obtain IP address" and "Automatically obtain DNS server address" as shown in the figure, and make sure to close the dialog box.

Enter cmd in the "Start" in the lower left corner, or press Win+R to pop up and run and then enter cmd, all the same. After pressing Enter to confirm, the DOS dialog box will pop up.

<> enter it in the DOS dialog box"arp -a"(Be sure to remember that there is a space before the minus sign), press enter, and the available IP address in the network will pop up, as shown in the figure (each network is different, and the IP in the picture is for format reference only).

<> is still the last step, at this time, find a more pleasing number in the pop-up IP, continue to enter the "ping format statement, remember,The one given here" is for format reference only, readers should enter the IP address that pops up on their computer, and"ping"Remember to add a space after that. If you try one IP address and it doesn't work, you can try another one. That's it!
