Unable to connect wireless network using Broadcom BCM4312

Postby bsmith12345 on Mon Dec 31, 2012 8:11 am

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:

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.

http://www.broadcom.com/support/802.11/linux_sta.php

http://www.broadcom.com/docs/linux_sta/README.txt

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.
