Ubuntu 13.04 No wireless desktop

[roygbiv808]

I just started using Linux so please be patient. I have a desktop with a USB internet adapter. It works fine on the windows side, but Linux will not run it. I have 13.04 32bit. I figured out it has a Broadcom BCM 4323/0846:9011 in the netgear adapter. There is not even an option to turn on wireless. Wired is fine.
Thanks in advance!

So I have figured out how to fix it. If you have a desktop and the option for wi-fi is not there in networks and you have a USB wi-fi adapter hopefully this helps. I was able to use these intructions since I had a wired connection.
The following I copied directly from the ubuntu docs but I made a change since I came across a problem part way through. To see the original instructions: https://help.ubuntu.com/community/Wi...er/Ndiswrapper

Install ndiswrapper it allows you to use wireless cards and in this case usb adapters

sudo apt-get install ndisgtk

Then check the chipset on your usb device

lsusb

It will look something like this: 104c:8400 mines was just numbers.

Next go to the ndiswrapper list: http://sourceforge.net/apps/mediawik...itle=Main_Page
you can also find it here: https://help.ubuntu.com/community/Wi...er/Ndiswrapper Step 3.2 number 1.

Find your driver: I have a netgear 3100 so I chose that one.
Download using archive manager to extract the files and remember where you saved it on your computer

Next install the driver:
Check the folder for the .inf file and make note of the name. It is case sensitive.

sudo ndiswrapper -i <DRIVERNAME>.inf

To make sure it was installed run the command

ndiswrapper -l

If the driver is installed correctly, you should see the following output:


Installed ndis drivers: {name of driver} driver present, hardware present or:

{name of driver} : driver installed device ({Chipset ID}) present

Next load the driver:

sudo depmod -a sudo modprobe ndiswrapper

To check it again try the commands

ip addr iwconfig

If this worked great. But if you get an error when trying to run the command

sudo modprobe ndiswrapper

and this is your error:
"FATAL: Module ndiswrapper not found"

it has already been solved in another forum: http://ubuntuforums.org/showthread.php?t=1987695 just install the rest of the package. Then run the commands that are listed. I did see that Mint was not able to use the same steps..FYI

sudo depmod -a sudo modprobe ndiswrapper

again and it came right up for me.
