Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I'm user of Xubuntu 12.04 on an AOD270 Netbook.

It has a built-in chipset for the wifi connection Broadcom 4313 14a4:4727, which I'm trying to get to work in both normal and monitor mode.

I got it to work at once, but with a bug (the channel fixed on -1). While I was searching for the fix trying different solutions, It stopped working. So, bottom line, I had the chipset working with the right driver - but with a bug - I broke it; and now I'm trying to get all working again.

When I'm trying to load module brcm80211; with the following command:

sudo modprobe brcm80211

The terminal retrieves this message:

FATAL: Module brcm80211 not found.

I fear I deleted the module while trying to fix the -1 bug.

How can I fix this?

lspci and lsmod information are attached next.

I have already read Broadcom brcm80211 installation from source
