Hi

It's a long time i'm using Ubuntu, but still a beginner. So, after searching without results, now it's my first post in this Forum!

I have an ASUS EEE 1001px with Ubuntu 12.04. I tried to update to 12.10 but everything crashes, so I re-installed 12.04: now Network manager doesn't detect any Wi-fi. I'm sure that there is a Wi-fi, and I'm sure it's not a problem with Wi-fi button (in my computer FN+F2). Indeed there's something strange: before, when I type FN+F2 I activate the Wi-fi Network in Network manager (I mean I check or uncheck the second option of the network manager applet). Now nothing happens.


I installed the Broadcom STA drivers: "This package contains Broadcom 802.11 Linux STA wireless driver for use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-, BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-based hardware".


And I can show you the results of some commands (i put in blue what i type) I saw frequently in other posts: I hope this will be usefull.



Thank you in advance!
