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 wlan1.

  *-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

lsusb:

Bus 001 Device 002: ID 2001:3308 D-Link Corp.

What might be the issue or how do I troubleshoot it?

Thanks.

try downgrading the security of your wifi network. If its a lousy reverse engineering of the driver. It might not support more modern / secure wifi modes like WPA2

Check to make sure that you have the right WPA version(WPA, WPA2) or Encryption protocol(TKIP,CCMP/AES).
