The name of the computer does not match the MAC address

One way is to find a network administrator and update the MAC address of your computer's network card. Another way is to do this if you know the MAC address of the previous network card, and see if you can:

Right-click on the net neighbor, properties, right-click on the local connection, properties, and then click on the connection when using... In the configuration on the right, click Advanced in the pop-up window, then find and click on the Network Address item, click on the value on the right (the default is to select Non-existent), and add the previous MAC address to the value. It is in the form of 0e4c5a0001ac, not 0e-4c-5a-00-01-ac.

If you add OK, the NIC will be disabled and then enabled. Then see if you can get on it again.

The MAC address is the unique address of each network card, which is different, and your school binds the MAC address to the computer name, as long as there is a difference, you can't get on it.

Could this be the case.

Your school's education network requires you to enter the computer name, user name, and password to log in, then the user name and password are your authentication account, and the computer name is to confirm your computer (here is to confirm your network card MAC address), and your computer is changed, so the MAC address naturally does not match. The solution should be to find your school's network administrator and ask him to update your account information and update the MAC address of the network card of the computer you are currently using.

Generally, a network card has only one MAC address, and it is fixed.

The computer has changed (the network card is different) and the MAC address is different, of course, you can't log in.

Change the "WAN port MAC address" of the new route to the same as the "WAN port MAC address" of the old route.

The router configuration WAN port settings" should be available inside.

The route binds the MAC to the IP, and you can only log in to the route settings, or find the administrator.

MAC address.

bai is the physical address of the network card, and du has been set by the producer when the network card is produced, dao

It is unique and is impossible to change the version willingly.

The latter right address is the IP address of the network, which is an Internet IP address assigned to you by the departments of telecommunications, Netcom, or campus network, which is equivalent to an Internet license, which can be changed, and as long as it is valid, it will not affect your Internet access.

The MAC address can be changed.

Upstairs may be right, you are not looking at an interface, a mouth, a PPP

It has nothing to do with computers. I installed a load balancer in the factory, controlled the Internet access, and fixed the IP MAC, with other IP MAC can not access the Internet!

What doesn't match the MAC address? It has nothing to do with the computer, it is generally related to the device bound to the IP mac.

It shouldn't be found, MAC address is the physical address of the network card, only the PC computer can be identified, the ordinary network can not find the address, unless you are a local area network, each computer has a fixed IP, IP and MAC must match to access the Internet, then the network management can know that it is the machine when you see the MAC or IP. After all, it's still an IP lookup.

Use the cmd command (click "Start" "Run", enter "cmd" and press Enter), ping fen000499f5k, you can get the IP address of the computer.

Use the cmd command, nbtstat -a, to get the name and MAC address of the computer.

You can also use ping -a to get the name of the computer.

You can see the IP address of the MAC, and then you can find the name of the computer by the IP.

The MAC address is an ID card unique to each NIC. It's not going to change, but if you do see it, it's definitely a software problem, for example: ARP virus fake MAC address.

It is recommended to disinfect the virus and reinstall the system.

However, if there is a 691 error in the connection, in Telecom and Netcom, it should belong to the wrong account password and the ISP operator has not opened it (arrears).There are also some broadband connections that can be deleted and rebuilt.

As for the campus network, I'm not very clear.

Fix IE first, restore the system if it doesn't work, and redo the system if you don't have a system restore.

Could it be poisoning? Install a 360 firewall on your notebook and enable the ARP firewall on it.

Isn't it a notebook?

A local network card A wireless network card.

The MAC address is unique.

But it can be changed.

Satisfactory answerDream back to yesterda4 level2010-06-11Because the IP address is a 32-bit address assigned to each host connected to the Internet (the IP address is composed of two parts, one part is the network address, and the other part is the host address), and the MAC (Media Access Control, Media Access Control) address is the identification of the LAN (Local Area Network) node. The physical address of a network card is usually the EPROM (a flash memory chip, usually written by a program) burned into the network card by the network card manufacturer, which stores the addresses of the computer that really identifies the computer that sent the data and the host that received the data when transmitting data. An IP address is assigned to a host on the Internet if you set it to "Automatically get an IP address" in "Internet Properties - Protocol".

The address you get is different every time you boot it, while the MAC address is the same. So the IP and MAC address will be different every time you turn on the phone!!

Yes. The MAC address is one for each network card. He can't get on the net with any network cable. You can rest assured.

You've changed the routing login password. Just don't add it to him.

I don't think it's possible to change it to the same Mac as yours.

After you've set it up. You can surf the Internet with peace of mind. He can't get on.

No, the network of the dormitory is bound to the IP and MAC after paying the money, he can access the Internet as long as he connects to the server, that is, he can plug in the line, the MAC is the physical address of the network card, and each computer is different.

You should be using the function of the router's address pool, the host is automatically obtained IP and then surf the Internet, if you enter the router and bind the IP address to the MAC address, unless he uses software to change his MAC address, he may be able to play, or he will not be able to access the Internet
