12.10 no wireless with BCM4312

[Superkoop]

My primary issue is that my wireless does not work after I installed 12.10.

The output to rfkill list all:

5: hci0: Bluetooth
Soft blocked: no
    Hard blocked: no

The output to lshw -class network is:

The output to lspci -nn for the pertinent information is:

0b:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

Thus, it seems the solution would be to run:

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

However, here's the kicker, I don't have access to an ethernet connection right now. How can I install the necessary drivers through another computer? Is it possible to set up an ICS with Vista to download what I need?

Hello!
I don't know if you ever figured out how to download the files to restore your wireless adapter or not, but your suggestion fixed mine.

In my case, I used a USB WLAN adapter that IS recognized to install the necessary files.

Thanks for the tip!
