How to set up Broadcom BCM4312 wireless network in Ubuntu Server Linux

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.

[email protected]:/# lspci | grep Network

02:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) [email protected]:/#

[email protected]:/# apt-get update [email protected]:/# apt-get install b43-fwcutter firmware-b43-lpphy-installer [email protected]:/# ifconfig wlan0 up [email protected]:/# iwconfig [email protected]:/# iwlist scan > log_wifi.txt

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

[email protected]:/# 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!
