Modify the MAC address issue Urgent 100 points

The MAC address is the hardware'A unique identifier on the compilation', which cannot be modified, can only be cloned, and the cloning method is to bind the MAC address on the authentication server. In this case, you can first connect the computer bound to the MAC address to the LAN port of the router (but the router should not connect the wiring provided by the modem or ISP), and then use the MAC address cloning function of the router to copy the MAC address of the NIC to the WAN port of the broadband router.

The MAC (Medium Media Access Control) address, or MAC address, hardware address, is used to define the location of network equipment, which is composed of 48 bits long, 12 bits of hexadecimal digits, and 0 to 23 bits are the ** that the vendor applies to IETF and other institutions to identify the vendor, also known as the "organizationally unique identifier" (organizationally unique identifier). It is a sign that identifies LAN (Local Area Network) nodes. The 24 to 47 bits of the address are assigned by the vendor and are a unique number of all NICs manufactured by each vendor.

That is to say, the MAC address is like your ID number, which is born and cannot be modified, and you can use the MAC address to clone it if you want to modify it, or change the network card. MAC address cloning is not a modification in the true sense of the word, just a disguise.

First, right-click the properties of the NIC you want to modify (if it is a network cable connection, it is a local connection to Ethernet, and a wireless connection is WLAN).

Network tab, click Configure.

In the pop-up window, click the Advanced tab, select the network address (or network address) item, enter a new MAC address, note that the format is hexadecimal, and confirm.

Talking a lot is not necessarily the best!!

Changing the MAC address is unlikely to cause this to happen, and as you said, reinstalling the system is even more impossible! After reinstalling the system, the MAC address will be restored to your original one!

According to the analysis, it should be a problem with the installation of the network card driver and network cable, try to change the network cable, and install the latest network card driver!

It can be in the network card driver!

My Computer Properties, Device Management, Select NIC Properties.

In the advanced tab, there is a "connection speed and duplex mode" where you can choose between 100Mbps half-duplex and 10Mbps half-duplex. (You can choose one to change o(o...)

Optimizing the network connection is a great help for the stability of the network, the connection attributes, as long as the protocol, QoS, and network client are left in the network (ADSL users can change in the broadband connection or PPE connection).

It doesn't matter, the 100 and 10 you refer to are the speed between the network card and the motherboard, not your actual network speed.

The public server you are connecting to has a fixed IP address... You're just changing your computer's, and it's just recognizable.

It is caused by you replacing the PCI socket of the original network card, remove the network card, insert it back into the original socket, uninstall the driver, and reinstall it!

I don't want to disable the entire sound card, but I still need to be able to play back.

I just want to disable the microphone.,Set the audio input in the audio is something else.,But QQ can be used automatically when you move together.。

I just want the microphone to not work, can I change it in the registry?

Because children always voice chat, I want to disable this, and it's best that non-administrators can't modify it.

The system is XP.

It seems that what you want to change is not the mac but the description of the network card.

It's not easy to use a microphone, just pull it out.

This doesn't affect your use.

It's hard to change.

First of all, you need to know the MAC address.

Start-Run-Type "cmd", type "getmac" in the command prompt to get the MAC address of the machine.

First of all, use this book to ping the route, is this book already connected to the route?

Then take a look at whether the MAC address of your wireless computer is the same as the route saved, if you confirm that they are set correctly, there should be no problem.

It depends on the Mac limit you set, whether you can or can't limit the list of what you can and can't on.

There is also a situation where the router itself will have problems, and I have encountered several such before. Just factory reset the router and set it up again.

It's the same in my house.,I don't know what's going on and it's slow.,Even if you set a password.,Eh! Kind! I hope you find a solution soon, but I also hope that you pay attention to your image.

Can QQ come and help you see 282443085 remotely?

It's easy to do. 00-2f-c6-af-86-b8

You can start with the best one. From B8 all the way to EA, isn't it coming out? Hehe.
