Hi,
Thank you for taking the time to read this. I have searched Google, Linux Mint forums, and Ubuntu (12.04) forums for 3 days and have yet to have found a working solution.
I have a Dell laptop with a Broadcom BCM4312 card. Output of lspci -vnn | grep 14e4 is:
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
I have gotten as far as being about to see networks in my network list but upon attempting to connect to my network I recieve the notification "Activation of network connection failed". I have checked the basics such as ensuring the password is correct (even removed wireless protection to no avail).
Output of sudo /usr/lib/linuxmint/mintWifi/mintWifi.py follows:

Re: Unable to connect wireless network using Broadcom BCM431
If you have a working wired Internet connection then follow the steps here (you need the LP-PHY): https://help.ubuntu.com/community/WifiD ... etzal.29-1. If you don't have a working Internet connection, follow instead the steps further down on that page: https://help.ubuntu.com/community/WifiD ... net_access.
If you didn't know, Linux Mint 14 is based on Ubuntu 12.10. So follow the steps for Ubuntu 12.10.

Ok, ran "sudo apt-get install firware-b43-lpphy-installer" and got thiis:
camulus@Dell-Inspiron-1545 ~ $ sudo apt-get install firmware-b43-lpphy-installerReading package lists... Done
Building dependency tree
Reading state information... Done
firmware-b43-lpphy-installer is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 196 not upgraded.
I have tried switching between drivers and have tried removing "wl" drivers but I was informed that "wl" drivers were not installed. I have also checked under software sources / addional drivers and the proprietary driver is not in use. When trying to activate it, it fails without giving an error.
I'm sure the driver is installed because I can see wireless networks but I cannot connect to my network. I live near a school and have tried connecting to their open network but cannot connect to it either.

I was having the same issues ... I tried multiple installs of the recommended driver and firmwares listed.
My wireless finally worked when I went to the broadcom website and downloaded their hybrid driver and installed it manually. The README document is really helpful and has all the necessary steps.

It took me about two days of playing around and trying different things while using ethernet connection and it feels good to finally go wireless.
