b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found -> BCM4311 802.11b/g WLAN [14e4:4311] (rev 01) wireless controller not working on Compaq Presario C500 in Ubuntu 9.10

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

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

Step 4: Please also specify the exact model and make of pc that you are using.

Regards,

Mark

I'll get right on it, I just have to hunt for a cable. And sorry i forgot the make. Its a Compaq Presario C500. I'll get that info going once I get everything connected.

Thanks ahead of time,
Mike

i tried doing as the last link advised by putting sudo apt-get --purge remove b43-fwcutter, then rebooting and typing sudo apt-get install b43-fwcutter
but both times all i got was this message:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package b43-fwcutter

well I'm not sure what I did to fix it (i did go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware from the output i pasted) but the wireless is up now thanks for all your help (now I just have to remember the passwords)

1000 thanks
