What is the problem with the MAC address of the wireless network card used by the computer?

MAC addressIt is also called a physical addressHardware addressor link address, which is written inside the hardware when produced by a network equipment manufacturer. IP addressThe MAC address is represented in binary in the computer, the IP address is 32 bits, and the MAC address is 48 bits.

Organized by the IEEE (Institute of Electrical Family Pins and Electronics Engineers).

assigning, and the next 3 digits of the hexadecimal number 0a:8c:6d represent the serial number of a network product (such as a network card) manufactured by the manufacturer. As long as you don't change your MAC address, then your MAC address is unique in the world.

MAC address.

In order to prevent the IP address from being stolen, through a simple switch port binding (the MAC table of the port uses static entries), you can prevent the theft of the MAC address when each switch port is only connected to one host.

The MAC (Medium Media Access Control) address, or MAC address, is an identifier used to represent every site on the Internet, in hexadecimal numbers, with a total of six bytes (48 bits). Among them, the first three bytes are assigned by the IEEE's registry RA, which is responsible for assigning ** (high 24 bits) to different vendors, also known as:"A unique identifier on the compilation"(organizationally unique identifier), the last three bytes (the lower 24 bits) are assigned to the production adapter interface by each manufacturer, which is called the extended identifier (only the file is not unique). One address block can generate 2 to 24 different addresses.

The MAC address is actually the adapter address or adapter identifier EUI-48.

How do I check my MAC address? 1. Enter the mobile phone setting center, in the network and WLAN, there will be an advanced setting about WiFi settings;

2. Press the function button from the network detection center to enter the advanced setting;

3. After entering the advanced settings, there will be a MAC address and IP address.

4. There is a "Random Valid MAC" on the interface, click to change the MAC address of the wireless network card.

5. Then click on the "Modify" option in the software page.

6. After the modification, the interface will pop up a window to confirm the modification of the current network card MAC, click the "OK" option, you can successfully modify the MAC address of the wireless network card.

4. Next, click the "Get Random Valid MAC" button on the page to change the MAC address of the wireless network card;

5. Next, click the "Modify" button in the software page;

6. Finally, in the pop-up dialog box on the page, click the "OK" button to successfully modify the MAC address of the wireless network card.

Use the MAC address modifier to modify the MAC address of the wireless NIC. Run the k-mac address modifier, which is different from the format of method 1, the MAC address entered here should be entered with "-", after the input is completed in "New Mac", click "Apply".

First of all, you need to obtain the MAC address of the correct network card that can access the wireless LAN before you can perform the following operations.

Step 1: Type cmd in the run of the start menu and press enter to open the command prompt window. If you are a Vista system, you can enter cmd in the "Search" box of the start menu and press enter, or you can press Win+R to bring up the "Run" window.

Step 2: Enter ipconfig all in the command prompt window and find "physical address." .

: 00-0c-29-e7-b2-8c" (Figure 1), followed by the number group is the MAC address.

If it is vista, it starts with the Chinese "physical address". Make a note of this string of characters.

Figure 1 Finding the MAC address.

Change the MAC address of the wireless NIC.

Once you have the correct MAC address, it's time to replace the network card. After naturally replacing the network card, the wireless LAN cannot be accessed due to the MAC address, and the next thing we will do is to modify the MAC address.

Method 1: Modify the NIC properties directly.

Step 1: Right-click on the desktop "My Computer" (Vista is "Computer") and enter the Device Manager "Network Adapters" to find the wireless network card.

Figure 2 Write a MAC address to the MAC address.

Step 3: In the command prompt window, enter ipconfig all again and verify whether the MAC address is successfully modified. As a side note: sometimes you need to disable and enable the network connection again or restart it for it to take effect.

Method. 2. Use modifiers to modify MAC addresses.

The previous modification method is obviously more cumbersome, and it is recommended to use a MAC address modifier to modify the MAC address of the wireless network card. Run the k-mac address modifier, and the format of method 1 is different, the input mac address here should be marked with "-", as shown in Figure 3. After entering in "New Mac", click "Apply".

Not on the outside because the MAC address is basically not duplicated, except for the only manual change in the world.

But if you surf the Internet at the same time with your desktop, you won't have a problem??? I don't believe it.

There will definitely be application failures, and the phenomenon should be intermittent.

Wireless routing or wireless network card, if it is routed, there is ** behind the route, just do it.

Delete the wireless network in the wireless network configuration preferred network in the wireless network attribute of the wireless network. Reconnect.

2. Check the physical address of the wireless connection card before modifying, open the command line window in the Windows system, open it by running the cmd command, and use the command to view;

4. Use TMAC to modify the MAC address of the wireless network card, select "Wi-Fi connection" in the network connection list, click "random MAC address" to let the system automatically generate a random MAC address, and then click "change now";

5. After changing the address of the Mac, the network connection will be interrupted, and the network connection can only be used normally after restarting the computer.

5Compare the content under the 0007 ndi params primary key,Found it,Hehe,Exactly correspond to all the options in the advanced tab of Windows,So I believe you already have a general idea。
