I just installed Kubuntu 12.10 and as I knew my wireless driver would not be recognized, I installed it manually through here. I suppose I shall mention that I also had to do this.

The driver worked just fine until I restarted my system. Since then I can't even start over.

My wireless card is realtek 8723

The oly lead I have is this piece of log:

11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <info> wpa_supplicant started
11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs
11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <info> (wlan0): supplicant interface state: starting -> ready
11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <info> (wlan0): device state change: unavailable -> disconnected (reason 'supplicant-available') [20 30 42]
11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <warn> Trying to remove a non-existant call id.
11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <info> (wlan0): supplicant interface state: ready -> inactive
11/14/12 07:35:21 AM    timucin-W150ER  NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs

I feel really bad that I have been trying so many things and even while I am trying them I get a problem at every step. I am really frustrated. You can the time in the logs, I didn't get up early. Just needed to share my feelings.

Even the ethernet cable I have use is short for God's sake, I have had to sit at this massively uncomfortable posture for hours.

edit: I discovered something interesting. When I boot my windows I see that my wireless manager says "disconnected" now. However when I start ubuntu after windows and modprobe rtl8723e wireless works just fine. Then again, when I restart ubuntu I am back where I have started. So now I have to start windows, restart my machine and do the modprobe thing to see wireless networks.

Have you tried using wicd? It worked for me in Kubuntu 11.04 while the built-in network manager failed. –  Oleh Prypin Nov 14 '12 at 20:50
