Toshiba l755-s5256 NO Lan NO WiFi 10.04 LTS

Just bought a new Toshiba Laptop L755-S5256. August 20, 2011

I want to use the WIRED LAN connection and I do not have a Wireless Network.

My goal is to get the LAN connection to function. If I have to, I will set up a wireless network to access the internet.
I would prefer to use a wired connection.

Installed 10.04 LTS along side Windows 7 that was pre-installed.

Everything that I have tried so far seems to function, EXCEPT the LAN connection and the WiFi icon in the top panel shows a RED "!" through the WiFi symbol.

Then I went to Ubuntu and noticed that there is a 10.04.3 LTS .

I downloaded the 10.04.3 intel desktop x86 .iso and burned it to a CD, thinking that there may be new drivers (etc.) for new hardware on a current new Toshiba Laptop.

When I went to overwrite 10.04 LTS with 10.04.3 LTS, I did not see a way to uninstall 10.04 LTS and Not Destroy Windows 7 in the process. It looked like I could create another 10.04.3 LTS partition, but I don't want to create a bigger mess.

I ran 10.04.3 LTS Live to see if it would see the LAN and WiFi network. It DID NOT see the network.

I noticed that there were new packages on 10.04.3 LTS that I could access running 10.04 LTS from the 10.04.3 LTS CD.

I installed them into 10.04.LTS and they are:

ndisgtk 0.8.5-1

ndiswrapper-utils-1.9 1.54-2ubuntu1

ndiswrapper-common 1.54-2ubuntu1

and now I have a NEW dialog box under System > Administration > Windows Wireles Drivers , looking for a .inf file .

The wired LAN still does not work.

Here is some data from the terminal from commands that I found in forums searching for answers before posting this in launchpad.net. I have limited Linux knowledge and would appreciate any help I can get.

Do not assume that I have the knowledge of a system administrator when you provide help. If you skip a step, I will be lost.

If I have to remove 10.04 LTS , how do I preserve the existing Windows 7 software installation ?

Also, if we can solve this issue, can I run the 64 bit version of 10.04.3 LTS or is that just for AMD ?

Thank You in advance ! :)

All The Best.
