Hello everyone!

How to configure the Broadcom BCM4312 wireless network in Ubuntu Server Linux. This is the wireless board of my old laptop model: (Philco PHN14003)

At first we need to confirm that you really have the BCM4312.

root@linux:/# lspci | grep Network
02:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
root@linux:/#

root@linux:/# apt-get update root@linux:/# apt-get install b43-fwcutter firmware-b43-lpphy-installer root@linux:/# ifconfig wlan0 up root@linux:/# iwconfig root@linux:/# iwlist scan > log_wifi.txt </pre>

Than, you have to find your SSID inside your .txt file. In my case, the name is “safe”

root@linux:/# wpa_passphrase MY_SSID MY_PASSWORD > /etc/wpa_supplicant.conf

You have to put your ssid and your wireless password as you see.

Thus, we have to edit the /etc/network/interfaces and put this:

<code>auto wlan 
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant.conf</code>

 

That’s it! Just reboot with reboot -n and its working!
