About the Product
WL568USB provides wireless connectivity to desktop and 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 WL568USB the capability to
communicate with other devices and use the Internet service available in the wireless
network.
WL568USB 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. WL568USB 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 a Windows-based software called WL568USB Utility that can be used
to connect to wireless networks and create profiles which remembers the configuration
details for a wireless network.
Note:
Note:Note:
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.
