How to find out the MAC address of the computer? What is the MAC address for?
Media Access Control is assigned by the factory to all Users who understand how to find out the MAC address, are free from many connection problems and can freely use the Internet when needed.
What is the MAC address for?
Any network card that is in the gadget has its own address. It is used to recognize the device on the network. Also, the address can be useful in order to bind the computer to the login in the system. Internet providers using the MAC address set the settings so that it is impossible to use someone else's name from another device.
What if there is no internet?
To solve many problems with connecting a computer to the network, the user must know how to find out the MAC address and how to change it. As an example, take the connection of the Internet cable to another interface. If a new card is installed, the address will change, causing the device to stop connecting to the network. In this case, you can choose one of two solutions to the problem:
- Report to the provider a new MAC address. Employees will enter it into the database instead of the old one, and the user will again be able to freely access the Internet. But this option does not suit everyone, because you need to spend time: the address is unlikely to be changed at the same time.
- Change the MAC yourself.
Where to look for a unique address?
Not all users know their MAS. To view it there are several ways. So how do you know the MAC address?
The easiest way is to go to the “Start” tab, then go to the “Control Panel”. In the “Network and Internet” menu there is a line “Control Center ...”. To view the address, you need to click on the name of the connection. In the column “Details” the MAC will be displayed, simply increase the label.
A unique address consists of characters that will be separated by a hyphen or a colon. It should be remembered that the letter "O" here can not be, because the code consists of the letters "A" - "F" and numbers. The inconvenience is that the characters cannot be copied, so you have to manually enter them.
To go to the "Control Center ..." section, you can right-click on the corresponding icon.
Reflecting on how to find out the MAC address of the computer, you should not forget about the command line. To do this, press the key combination Win + R. In the opened input field it is necessary to drive in cmd. The ipconfig / all command is written in the black window. After that, all information about network adapters will become available. You can find your card by name, which will be highlighted in red.
Do not pay attention to virtual devices. They begin with the words "Tunnel Adapter ..." or "TAP ...". On the real map will be presented the most information.
You can view the MAC in the “Physical Address” parameter. To copy it to the clipboard, you need to right-click and select the "Mark" function. After the desired text is selected, you must press the right key.
If you need to connect another computer to the Internet without disconnecting the old one, the easiest way is to change the address of the card on the new device. You can work on them alternately, using the PC that is needed at the moment. It is enough to pull the cord out of one device and connect it to another.
But in order to do such manipulations, you need to know how to change the MAC address.This can be done in the following ways:
- Using the settings of the network card. To do this, go to the "Network Control Center" and call the "Properties" window. You can also go to the "Change adapter settings" menu. To change the unique address, you need to find the network card and click on it with the right mouse button. Select "Properties" - the "Edit" window will open. In the tab "Advanced" you need to find in the list the item "Network address" or "Physical address". After that, you need to put a switch in the input field and insert the necessary MAC address there. To undo this action, just return everything to its original position.
- Applying special programs. This option is especially relevant when the network card does not have the necessary parameters. Most often, people use the program Macshift. It works directly from the command line and does not need to be installed. To change the MAC address, you need to run a utility that has the following parameters: macshift –i. "Connection Name" 00112233AABB. You can see this data in the “Network Connections” window. But this method has a drawback: changing the address on the command line is not very convenient.Some users install the Ryll MAC Changer program, which has a graphical interface.
In the opened window, you must select a network card, and then register a new MAC address. After that, you need to activate the Update MAC option. For the new parameters to take effect, the device must be rebooted. Some users prefer to go to the "Control Center ..." tab and select "Change settings ...". On the connection, you need to right-click and click "Disable" and then "Enable" again. If it becomes necessary to return everything to its original state, it is sufficient to activate the Reset Default MAC option.
