I'm trying to salvage a laptop long-abandoned by its owner and, just recently, given to me. Things were so messed-up that I just had to wipe the slate clean by replacing everything with Ubuntu 13.04.

In its post-installation state, it couldn't use wireless Internet, only wired. I checked the "Software and Updates" window's "Additional Drivers" tab to find this:

- Broadcom Corporation: BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller
This device is not working.
    (-) Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)
    ( ) Do not use the device
- Unknown: Unknown
This device is not working.
    ( ) Using Non-free firmware for Linux kernel drivers from linux-firmware-nonfree (proprietary)
    ( ) Continue using a manually installed driver
    (-) Do not use the device

As can be seen, I had the Broadcom driver installed.

The problem is that the installation has frozen at 80%. I'm thinking that the installation might need some information online to continue, but the laptop has lost its ability to sense the wired Internet it is already connected to. How can I make it re-sense the wired Internet?

Here is the current data on the laptop's state:

As to the second device, I am not sure what it is, but the "Continue using..." seems to imply that the driver is already there ready to be used, so I am thinking of choosing the second option after the first problem is resolved. Would you guys agree?

Thanks for your time.

Take care, Kalayaan 001

Please post what lshw -C network and lspci -nn tells you. –  grimpitch May 13 '13 at 2:09

For the wired card: run modprobe b44 and check with ifconfig, and I need you to show me the output of lspci -nn, not just lspci. –  grimpitch May 13 '13 at 2:33

Installation of the Broadcom STA wireless driver adds a blacklist for the module ssb which is also used by the driver b44 used by your ethernet card. If you load the driver b44:

sudo modprobe b44

I suspect your ethernet will come to life. If, after you do this, your wireless is still working as expected, undo the ssb blacklist:

gksudo gedit /etc/modprobe.d/blacklist-bcm43.conf

Comment out the ssb line:

#blacklist ssb

Proofread, save and close gedit. You should be all set.
