Wlan problems after installing Ubutun 14

[schwindelubuntu]

Hello everybody,

i've recently installed ubuntu on my Lenovo Thinkpad x200.
Due to the fact that my internal wlan modul sometimes not works correctly i bought an usb device from edimax.
But the whole wlan does not work on a fresh installation. Below some information about my system an the hardware:

Could some one give me a hint, please? Thanks!

What's the output of rfkill list and lspci -k

[kubicle]

rfkill --list

You probably mean rfkill list

[SteveRiley]

Yes, you're right. I have just taken my hyphen key out back for a good beating. And I fixed my post.

Any suggestions?

[SteveRiley]

I'm a little perplexed because rfkill shows nothing is blocked. Yet the ring buffer shows an entry indicating the kill bit is enabled, and your Network Manager state file indicates that wireless is disabled. At this point, I'd have to go Googling around. Have you searched for anything similar yourself?
