Hi,

Please first connect your network card 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: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website 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 restart. 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|CX|eth|ipw|irmware|isl|lbtf|ndiswrapper|NPE|ound|prism|rtl|rt2|rt3|usb|witch|wl'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo lsmod; cat /var/lib/NetworkManager/NetworkManager.state; sudo /etc/init.d/networking restart

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

The error "b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found or load failed" means that b43-fwcutter is not installed yet on your pc. And that means that the Broadcom firmware for your wireless card is not loaded or installed yet.

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following 2 commands into the Linux Terminal. Press <enter> after each command.

sudo aptitude update
sudo aptitude install b43-fwcutter

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

After installing b43-fwcutter, please reboot and then retest wireless.

I have seen this Broadcom error message so many times before. The reason why the Broadcom wireless driver does not work out-of-the-box in Ubuntu , is because the firmware for your wireless card is proprietary.

The firmware files for your wireless card are not allowed to be included as part of the default Ubuntu install, because it is non-free software.
