What is a USB network adapter?
A Universal Serial Bus (USB) network adapter is a computer accessory that provides a standard or wireless Internet connection to the computer to which it is connected. This type of adapter connects to the computer through a standard USB port and rarely requires more than a few clicks to install. USB network adapters are sometimes required for game consoles.
A wireless network card is used primarily for older computers and sometimes laptops that do not have built-in wireless or WiFi functionality. By adding WiFi capabilities to a computer, the user can connect to a network from anywhere within range of that network. While most laptops already have wireless functionality, some older models don't. By installing a USB network adapter in a laptop, the user can connect to wireless networks in locations with free WiFi.
Another option is the wired USB network adapter. It is mainly used in buildings without wireless Internet access, but it is also an option for people who prefer to be connected by a cable at all times. A wired USB network adapter is a cable with a USB connector on one end and a network cable connector on the other. This is particularly useful for computers that do not have a network cable connection.
There are many different adapters made by different companies, but they all serve the same purpose. One of the main differences between adapters is the operating system for which they are formatted. Most require a simple driver download before you're ready, but others only work with certain operating systems.
Once the USB network adapter is connected to the computer, it is generally not necessary to leave it plugged in. Typically, a bundled disc is included with the Quick Install of the software required for the adapter. At this point, the adapter must remain connected at all times so that the computer remains connected to the wireless network.
The USB network adapter does not require a power cord because it draws power from the computer to which it is connected. Some adapters come with separate antennas, and it is important to place them where they can receive the strongest radio signal. The antenna should be close to the computer, but not on walls or where the monitor or computer blocks or interrupts the radio signal.
