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.

So the methods in Unity are:
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; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'Manufact|Product'; iwconfig; cat /etc/modprobe.d/* | egrep '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 'icd|etwork'; 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.

Regards,

Mark

yushrajkapoor@ubuntu:~$

Please proceed with the following commands:

sudo apt-get update

sudo apt-get install b43-fwcutter firmware-b43legacy-installer

b43-fwcutter exists in the Ubuntu repositories, but you will need a
working wired Internet connection in Ubuntu in order to locate it and
install it.

The only way to do that - in your case - is to connect the pc to the
wireless router using a LAN cable, instead of using wireless.

Then reboot your PC and run the following command:

sudo rfkill unblock all

Then retest wireless.

Hope it helps.

into the bug link https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/711397

Raj Kapoor (rajdotkapoor) said : #12

thanks marcobra, however, that is way too confusing to me to decipher...

For the convenience of others, the instructions in question are at https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/711397/comments/6.

The information you have provided us indicates that you are using the i386 (32-bit PC or 32-bit Intel Mac) version of Ubuntu, so the specific .deb package from http://packages.ubuntu.com/maverick/bcmwl-kernel-source that you need is https://launchpad.net/ubuntu/+archive/primary/+files/bcmwl-kernel-source_5.60.48.36%2Bbdcom-0ubuntu5_i386.deb (that's a Launchpad download link rather than a packages.ubuntu.com download link, because Launchpad is a better site for manually downloading .deb packages -- the https protocol decreases the likelihood of a bad download).

If you don't have the Synaptic Package Manager installed, you can install it in the Software Center -- it is itself provided by the package: synaptic.

After synaptic is installed, quit any other package management utilities (including the Software Center), run Synaptic, remove the currently installed bcmwl-kernel-source package (use "Mark for Complete Removal"), then install the .deb package downloaded from the above link.

Then follow the rest of MasterNetra's instructions, which I have reproduced here for your convenience and that of others. (This is only a minority portion of his post, and I am guessing nobody will mind me reposting it under these circumstances.)

"After thats installed, go back into synaptic, find bcmwl-kernel-source again and this time, select it, and goto "Package > Lock Version" to prevent it being upgraded back to the broken natty version. After all that, restart your computer and it should be working again."

Can you help with this problem?
