b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found -> BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02) not working on Dell Inspiron 5100 in Ubuntu 9.10

Asked by David Hall on 2009-10-30

I have just installed Ubuntu 9.10 on a Dell Inspiron 5100. All aparently went well except that I cannot connect to my wireless network. The computer has no built-in wireless capability but does have a Linksys Wireless-G PC card (802.11g). Is this card supported? Is there additional software required?

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.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -C usb; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep iwl; iwconfig; sudo /etc/init.d/networking restart; dmesg | grep ath

Step 3: Please post results (copy/paste terminal output) on this thread

Regards,

Mark

Mark,

Thanks for your message. I have run the command as you requested but am having difficulty posting results. The OS does not correctly support the keyboard of the Inspiron 5100 (no '@' symbol) so I am unable to log in to launchpad. I'll keep trying with the keyboard layout but any suggestions you may have would be appreciated. This is coming from my other computer.

Regards,

David Hall
