I just installed Linux Mint 14 Cinnamon on my laptop, but I can't find where to connct with wifi, I Googled about it and I found that I've to enable my wifi adapter in Software Sources, so I did enable it and then I restared my laptop, but this didn't solve my problem. When I open Software Sources again I find that my wifi adapter is not enabled.
When I log in to my session, I get a notification which says :
Network Disconnected – you are now offline
My wifi adapter is a: BCM4312 802.11b/g LP-PHY
This is what I get when I run the command iwconfig :
lo no wireless extensions.
eth0 no wireless extensions.
When I tried to install this package firmware-b43-installer_015-14_all.deb, I got this message :
Selecting previously unselected package firmware-b43-installer.

problems prevent configuration of firmware-b43-installer:

firmware-b43-installer (–install): dependency problems – leaving

After that I installed b43-fwcutter, and then I tried to install the package firmware-b43-installer_015-14_all.deb but I got this error :
An unsupported BCM4312 Low-Power (LP-PHY) device was found. Use b43
LP-PHY firmware (firmware-b43-lpphy-installer package) instead.
So I removed firmware-b43-installer_015-14_all.deb using Synaptic Package Manager, And then I installed the package firmware-b43-lpphy-installer, but I got this message :
