Ubuntu Networking :: Create Wireless Network Hotspot ?

I connected a USB Wireless Dongle (Sapido AU-4512S) on my Ubuntu 10.04 64bit. I wanted to share my wired internet connection from my pc to my friend's laptop.

So, I did the following:

1. Installed ndiswrapper-utils, ndiswrapper-common and ndisgtk in Synaptic Package Manager.

2. Installed Windows 7 64bit driver of my USB Dongle through Wireless Network Drivers(ndisgtk)

3. Now it says, net8192su -- Hardware present: Yes

4. Created a Ad-hoc connection clicking on Network Manager > create new wireless network..

5. Edited the Name, set Security to WEP 128-bit Passphrase and entered my desired password.

6. Finally clicked Create but it says "Wireless Connection disconnected"

I'm thinking about maybe the problem is with my dongle so I checked by using the command:

Code:

which gives me information about wlan0

The next thing I did worsen the situation. I unplugged the USB dongle ang plugged it again. This time,

Code:

gives me no result anymore.

Also, the option that says "create new wireless connection" disappeared in my Network Manager Applet now.

Now I have no problem. To restore the "Create new wireless connection" in my Network Manager Applet and finally create a wifi hotspot using my wired connection from pc.
