The RTL8188CUS USB wireless card will not connect to wireless networks. The connection is attempted over and over again, and the password prompt reappears each time if the network has one, but a connection is never established. There is a workaround for this bug: Drivers can be obtained from the Realtek website. But they are required in order for the hardware to function properly. [3] Keywords.
