Change MAC Address in Windows

Change MAC Address in Windows

It is not advised to change the MAC address on networks as it may create conflicts and sometimes, may fail to appear on the network. But if you want to change the MAC address for some reason, it is an easy process.
1.    Press Windows Key + Break or Pause key to open System Properties window. If the Pause key is combined with the Shift key, you may need to press Win+Fn+Pause key.
2.    Click on Device Manager to the left side of the System window
3.    Once the Device Manager dialog appears, look for the category named Network Adaptors
4.    Click on the plus sign preceding Network Adaptors to see all the Network cards attached to your computer;
5.    Select the network adaptor whose MAC address you wish to change
6.    Right click on the network adaptor and select Properties
7.    Click on the Advanced tab.
8.    In the list of available options, select Locally Administered MAC Address or Network Address; note that only one of the two options will appear based on the type of your network adaptor
9.    When you select one of the above options, you will get a text box saying Value.
10.    Type a six digit alphanumeric code in the Value field after selecting the radio button; note that you do not have to type the dashes or full colon; if you wish to type 00:4f:gH:HH:88:80, you simply type 004fgHHH8880 without any dashes or full colons; adding dashes may result in error
11.    Click OK to close the dialog box
12.    Close other open dialog boxes (if any) and close the Device Manager

That is the simplest method to change the MAC (Media Access Control) ID of the network adaptor.

You can also use some of these free MAC Address Changer Tools.

Types of Ethernet 4 pairs Twisted cable:



The Ethernet 4 pairs twisted cable is mainly divided into three categories:

1- Straight Cable:

This cable is mainly used for communicating b/w two different devices. It can be made very simple /easily. You should to keep the same color combination on both the ends of the connector. Here I am mentioning here the standard color combination which you had to keep on both the end:
Straight Cable Standard
Straight Cable Standard

Straight Cable Color Coding
Straight Cable Color Coding
          End A---------------------------------------------------End B
  • White Orange ------------------------------------White Orange 
  • Orange -------------------------------------------- Orange 
  • White Green -------------------------------------- White Green 
  • Blue ------------------------------------------------ Blue 
  • White Blue ----------------------------------------- White Blue 
  • Green ----------------------------------------------- Green 
  • White Brown -------------------------------------- White Brown 
  • Brown ----------------------------------------------- Brown 


2- Cross Over Cable:

This cable is mainly used for communication b/w two same devices. The color combination you should to make to make is to replace the 1 number cable at one end with the third number cable at the other end & the 2 number cable at the one end with the 6 number cable at the other end. You can use any color combination for it but the standard one use is what I am posting here:
Cross Over Cable
Cross Over Cable
       End A---------------------------------------------------End B
  • White Orange ------------------------------------ White Green 
  • Orange -------------------------------------------- Green 
  • White Green -------------------------------------- White Orange 
  • Blue ------------------------------------------------ Blue 
  • White Blue ----------------------------------------- White Blue 
  • Green ----------------------------------------------- Orange 
  • White Brown -------------------------------------- White Brown 
  • Brown ----------------------------------------------- Brown


3- Roll Over/Console Cable:

The console cable is mainly used for configuration of switches and routers. The one end of the console cable is RJ-45 and the other end is serial port connector DB-9. You connect the RJ-45 connector to the console port of the router/switch and the DB-9 connector to the serial port of the PC. It is green in color. You can also make a console cable from Ethernet cable if you don't have a console cable. The combination for console cable is given as under:

Classification of Devices in networking

Classification of Devices:

The devices in networking has been divided into two groups which are mention below:


Group-1:

The group-1 devices included of :
  1. PC
  2. Server
  3. Router etc

Group-2:

The group-2 devices included of :
  1. Switch
  2. Bridge
  3. Hub
In order to communicate these devices with one another we will use mainly two types of cables, i.e straight Cable & Cross over cable. The straight cable is used for connecting the group-1 devices with group-2 while the cross cable is used for connecting the group-1 devices with group-1 or group-2 devices with group-2, i.e if we want to connect to different group devices then we will use a straight cable else we will use a cross over cable.
