I have recently purchased a USB WiFi adapter with a Realtek chipset for my netbook. Network-manager detects it well enough and can see my home WiFi network too, but when I try connecting I am just prompted endlessly for the WPA password, as if connection is somehow rejected or fails (I am using the right password).
A series of info about my network setup can be found here. The relevant network interface is
*-network description: Wireless interface physical id: 2 bus info: usb@1:1 logical name: wlan1 serial: 80:c0:b0:70:e0:20 capabilities: ethernet physical wireless configuration: broadcast=yes driver=rtl8192cu driverversion=3.0.0-13-generic firmware=N/A link=no multicast=yes wireless=IEEE 802.11bgn
Bus 001 Device 002: ID 2001:3308 D-Link Corp.
What might be the issue or how do I troubleshoot it?
