How to install wifi driver on Ubuntu 12.04LTE?

Hello Experts,

I am a completely new Ubuntu user (switched from Windows) and I just installed 12.04LTE on my MSI Wind U100 netbook last night.  Everything went well and it installed in a flash, but my big and only problem right now is the wireless does not work on it.  I don't get a list of wifi networks.  It just says that the wireless is disconnected.  The wired ethernet connection works good, but not the wifi.  The wireless card built into the netbook is the Realtek RTL8187SE Wireless LAN Controller (rev 22).  I don't know anything about Linux or Ubuntu so I don't know how I go about installing the driver.  I found the driver online and put it on a USB drive and tried to double click it on the netbook, but it won't work.  It seems as though I have to use the "shell" to install programs and I have no idea how to use the shell.  Can someone please provide me with step-by-step instructions on getting the wireless to work on my netbook/laptop?  I would greatly appreciate it.

Darr247,

I mistakenly put "rt18187se-source" instead of "rtl8187se-source" with the character after the "rt" being the error, but it looks like it installed anyway.  I re-inputted the correct command and it looked like it processed it also.  When I got to the third command, the terminal says "sudo: m-a: command not found".  Ideas?
This is what shows in the terminal after executing the three commands:

brent@BrentNetbook:~$ sudo apt-get install aptitude

dear john ,

it works , this way , but in future you have connection break outs ,drop outs follow my method .
some were having problems . if you get one then follow my method , the drivers are buggy .


thank you,

I wrongly assumed you already had module-assistant, I guess...
$ sudo aptitude install module-assistant
will give you the m-a script.
I try to save ndiswrapper as the last resort if there's absolutely no other way, even though many times windows drivers will have more features than linux drivers.  But for networking especially, windows drivers typically restrict things... like being able to use promiscuous mode.
