This is called the Media Access Control (MAC) address. Fortunately, there are many other programs available that do the same thing but show the user more details about their wireless connection.Most network equipment has a unique hardware identification number to distinguish it from other devices on the network. Windows and other operating systems ship with a WiFi signal strength meter but this is usually basic and doesn't really tell the user much about their wireless signal. Because of this, users need a standard way of diagnosing how portable and accessible their laptop really is. In the modern world of computer science, many people require that their computer systems be portable and accessible everywhere they go. The WiFi router for the network then receives this information, decodes it, and sends to the Internet through a wired, high-speed connection. Wireless signals can also be received via an external antenna plugged into the USB slot of a computer.
When your computer is connected to a wireless network, its wireless adapter will encode information into a radio signal and then transmit it using the wireless antenna that is normally built into the screen of new laptops. Wireless networks use radio frequency waves that are transmitted in the 2.4 Ghz to 5 GHz spectrum that are very similar to television or cell phone signal transmissions.
For example, WiFi started seeing a significant increase in usage starting with the 802.11B version of the protocol and has continued to be upgraded since then. This normally equates to an increase in potential bandwidth and security protocols with the standard. Every time a standard is updated, a new letter is added to the end of the designation. WiFi is the short-name that refers to the 802.11 networking standard that is promulgated by the IEEE. Also, the fact that it is almost impossible to buy a laptop that does not have a wireless card built into the screen will ensure that WiFi’s popularity continues to grow. This allows average consumers to setup networks anywhere that they have an Internet connection. The popularity of WiFi is due to its low-cost and how easy it is to setup the network. It is so widely used that it can be found in many homes, airports, cities, and schools world-wide. Over the past decade, Wireless networking has significantly grown in popularity. This is a good question, however you don't need to worry about the Ethernet connection,actually is not possible to
