View Full Version : [wubi] wireless device not ready firmware needed

September 13th, 2011, 08:16 PM
I just installed ubuntu 11.04 onto my Dell inpsiron 5100 laptop that was running windows xp. I used the wubi (?) that allowed me to keep windows because I wanted to test it out. Im glad I did because everything works fine except for my wireless internet connection. It works for windows but ubuntu cant find any connections. When I click the wireless button at top right it doesnt even let me click the wireless network stuff. I have the wireless enabled. It says something like : device not ready needs firmware. I have read through just about every single thread on this site, installed every freaking thing that everyone was saying to install and nothing works. I am not currently on the computer in question but will be soon and the ethernet connection works so I can post the lspci //seems like thats what everyone asks for .
Let me know anything else you need to see to help me please. I am just learning my way around linux systems and want to get rid of windows.

Thank you everybody

Mark your text and klick on the # Button in Advanced Mode to convert into code-tags.

You only need to install the firmware via

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

Still does not work. I restarted computer after typing in the lines you gave me. It did however change the look of the desktop. The toolbar at the top of the screen used to be black now it is gray and the icons have the same function but have changed appearance. When I click the network icon it still will not let me click on wireless networks. Underneath it still says device not ready(firmware missing) Im sorry for being a pain in the ***. Unless you have any other suggestions I do not think it was meant to be. Thank you for helping me. let me know if you have any other ideas.

Take the firmware from here:

wget http://media.ubuntuusers.de/forum/attachments/2480236/Broadcom_Firmware.tar.gz
sudo tar xvf Broadcom_Firmware.tar.gz -C /lib/firmware/
