(SOLVED) Wireless network issues

I installed Zorin Os 9 lite on my Compaq Presario V2000. Everything is working so far. I am having problems getting my wireless network card to work. I tried finding drivers, but nothing has worked. Can anybody help?

Can you please post here the results of the following terminal commands?

lspci -nnk | grep -iA2 net
lsusb
sudo lshw -c network
sudo rfkill list all
lsmod

Try this:
Download from here the b43 package: https://www.dropbox.com/s/n2tjz9jnj9xw5xb/b43.tar.gz
(I have uploaded it onto my dropbox account).
As soon as it is downloaded, go to your Downloads folder to find it (it's named b43.tar.gz).
Right click on it and select "extract here". A new folder will be created named "b43".
Open terminal (ctrl+alt+T) and write the following commands, the one after the other, pressing <enter> after each one:

sudo mkdir /lib/firmware/b43
sudo cp /home/$USER/Downloads/b43/* /lib/firmware/b43
sudo modprobe -r b43
sudo modprobe b43

Wait 5-6 seconds and your wireless should start working.
A reboot may be required.

Thanks it worked.

Glad I helped my friend.

Needless to say, another 120 blue jewels to madvinegar!
