looking forward for your precious help.

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

Will install the cutter to extract the proprietary firmware you need.

with all respect to your efforts, this is not working with me.
the problem that I don't have an access to a wired connection for installing that missing firmware.
I need to know how to download it manually and how to install it manually to Ubuntu.

anyway, I was so dispersed enough to try that command through terminal and got the following output:

udo apt-get install b43-fwcutter firmware-b43-installer
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package b43-fwcutter
E: Unable to locate package firmware-b43-installer

please help me getting that firmware and install it manually.
thanks in advance for your precious support.

Try:

sudo apt-get update

first

this is not applicable for my case.
I don't have access to a wired connection. how my Ubuntu will be able to get any update???????!!!!!!!

I tried it before and it didn't work.

I need to download the required driver and install it manually to activate wireless in Ubuntu then I will proceed with the rest of the updates.

Its a LAPTOP and so is MOBILE. So you can move closer to the router (or any router), use a wired connection and get the packages you need.....think about it.

You can also use the install CD as a source of packages and install from there but the wired connection will be significantly less system tweaking. You can also use the wired connection to get fully updated

thanks

Dears,

anyone else can provide me the required firmware and the way to install it manually to Ubuntu?
I tried to proceed with the last answer but I really don't have any access to the router or having a wired connection in my workplace.

looking forward for your precious help.

I downloaded all the XP OS wireless drivers available for my machine from HP official website.
I just need help about how to try to install it manually to Ubuntu as the drivers are download in EXE form.

The firmware is in your system, the firmware cutter just copies it so your OS can use it.

Can you reboot and give the output of the command I initially gave

Thanks
