wl driver from bcmwl-kernel-source not working after kernel update -> UNCLAIMED Wireless Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) not working anymore on Lenovo G455 0708 laptop in Ubuntu 12.10

Asked by Siddharth on 2013-01-26

I install ubuntu 12.10, During the installation it asked me for wireless connections and I could connect. In sometime it asked me to update the system. I did update it and the wireless networks disappeared. I cant find a list of any wireless networks anymore. Tried everything I could but failed. I have to use an Ethernet cable to connect. It does not give me any options or the list of wireless network. I installed RUtilT WLAN manager tried to run it and got an error saying "No wireless network interface available". Please help.

Hi,

Please first connect your wired network adapter to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1:

If you are using the Gnome interface, open the Terminal console via "Applications->Accessories->Terminal"

If you are using the Unity interface, the easiest way to open the Terminal is to use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.

The methods in Unity are:
Press Control-ALT-T key combination.
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal

Step 2: Please copy-paste the following command from https://help.ubuntu.com/community/WirelessTroubleshootingProcedure in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | egrep -i 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'anufact|roduct|erial|elease'; iwconfig; cat /etc/modprobe.d/* | egrep '80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl'; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|egrep 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; sudo lsmod

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Step 4: Please also specify the exact model and make of your PC (if known) on this thread

Regards,

Mark

Thanks for the help.

Please open a Terminal and execute the following commands:

sudo apt-get update

sudo apt-get install linux-headers-generic

sudo apt-get install --reinstall bcmwl-kernel-source

Source: http://forum.ubuntu-fr.org/viewtopic.php?id=1171261

Then retest wireless.
