I cannot connect to a wireless network. When I try to connect, the network manager asks for a password, but drops connection after a few seconds. Syslog show that the connection disconnects during the handshake. Relevant log-

Jul 13 20:50:06 Daniel-PC NetworkManager[988]: <info> (wlan0): supplicant interface state: 4-way handshake -> disconnected

I have no problems connecting to this network from my Windows installation or my Lubuntu laptop.

System setup- Lubuntu 13.04, fresh install. WiFi adapter TP-Link WN-822N, Realtek chip.

Can you add the output of lsusb to the question. That will, hopefully, show the chipset. –  mikewhatever Jul 13 '13 at 15:31
    
Thanks for the edit. It's Realtek RTL8192CU, which means you are affected by this bug. There is no fix for 13.04 yet, but I hope, in 13.10, it will wrk out of the box. –  mikewhatever Jul 13 '13 at 19:48
