Get Wireless working in Ubuntu 7.04 Feisty Fawn

Non-working wireless internet is a common problem which can be easily resolved. All you need is
1 ) Ubuntu 7.04 Feisty Fawn installed ( how obvious )
2 ) Internet access - can be on another computer if not the one on which you have Ubuntu.

So lets get working!

First download the following packages
ndiswrapper-common
ndiswrapper-utils-1.9
ndisgtk

Now transfer these files to the system with Ubuntu installed - use a USB Flash Drive if you have to. Just get the files there.

Place them in the same folder and run the following commands in the terminal ( have the folder opened in it ). Change the * to the right text and run in the same order given below.

sudo dpkg -i ndiswrapper-common_*.deb
sudo dpkg -i ndiswrapper-utils-1.9_*.deb
sudo dpkg -i --force-depends ndisgtk_*.deb

When installing ndiswrapper-utils-1.9, it will ask for the Ubuntu 7.04 Feisty Fawn Install CD ( if you haven't played with the repositories ) If it doesn't ask for it, most probably you have been playing with the repositories and it will use the internet instead of the CD.
Once installed, you have to blacklist the open source bcm43xx that comes with Ubuntu. The file /etc/modprobe.d/blacklist contains the blacklisting information. Just open it in gedit with root rights.

gksudo gedit /etc/modprobe.d/blacklist

And add to it...

blacklist bcm43xx

Now do a lspci in the terminal and find the name of your wireless card there. If you are using a USB wireless card, do a lsusb instead. Note it down because you will need it later. Like for me it says

03:00.0 Network controller: Broadcom Corporation Dell Wireless 1390 WLAN Mini-PCI Card (rev 01)

Now what you need is the windows driver for the card. Go to this page and find your card in the list(s) and get the required driver. Now you might need cabextract or unshield to get the real files from the setup. So install both of them

cabextract
unshield

Once you have the installed, open the folder where you have the setup in terminal and use the above given tools to extract it. In my case the command was...

cabextract -d drivers sp34152.exe
The "-d drivers" tells it to extract files into a new folder and call it drivers

And also do a ls *.inf in the folder where the files are extracted. It will list all files that end with a ".inf". Most probably there will be only one - note its name down. If there are more than one, go to this list again and see if it helps.

Go to System >> Administration >> Windows Wireless Drivers and press the Install New Driver button. Now browse to the folder where the files from the setup were extracted and point it to the inf file in it and you are done.

Now you just have to confirm if it installed correctly, start it and make it start at startup each time.

To confirm do a ...
ndiswrapper -l

If done right, it should say that the drivers are installed and stuff.
Now run it by...

sudo depmod -a
sudo modprobe ndiswrapper

And in the network settings, set it to "Roaming mode enabled"
Now we get it to start at startup, you have to add "ndiswrapper" to the /etc/modules file.
gksudo gedit /etc/modules

And add "ndiswrapper" to its bottom ( without quotes ), save it and restart. Enjoy wireless internet!
