About the Product
WL572USB provides wireless connectivity to desktop or notebook computers. The device
performs the function of a radio broadcaster and receiver to communicate with a wireless
network. This gives the computer connected with WL572USB the capability to communicate
with other devices and use the Internet service available in the wireless network.
WL572USB is capable of connecting with wireless networks that utilize the Wireless N
protocol. This device also supports connection to other wireless network standards like
Wireless G or Wireless B. WL572USB is easy to setup - install the necessary driver software,
connect it to an available USB slot, and then connect to a wireless network. The device
comes with Windows-based software called WL572USB Utility that can be used to connect
to wireless networks and create profiles which remembers the configuration details for a
wireless network.
Note: Wireless connection speed is not correlated to Internet access speed. Internet access speed from
popular broadband DSL or cable Internet services normally provides up to 3 Mbps connection, which can be
easily handled even by the slower Wireless B protocol.
