Installing Wifi Module for Dell Inspiron with Broadcom Corporation BCM4312 chipset

It was quite surprise that after installed linux Mint 14 Cinnamon edition, I'm having problem to connect to my home wifi. The Wifi Module is not working.

Wifi problem have long gone in Ubuntu ( at least for me) since I last manually installing them and I'm not even remember how should I configure them.

Anyway, to solve the wifi problem, first I need to know the wifi module chipset, then find the resolution via our mighty friend google.

Open terminal and type lspci.
Locate the network controller, in my case:

Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

After that, update the module package as suggested.

peiwei@linuxmint  ~ $ apt-get update 
peiwei@linuxmint ~ $ sudo apt-get install firmware-b43-lpphy-installer

Check Yes when asked for dependencies, restart and you are done.

Thanks nuno_nunes for his resolution.
