How to fix repeated "Authentication required by Wi-Fi network" [Broadcom BCM4323]?

Question

END RESULT******Netgear WNDA 3100 wifi stick will only connect to a network with no password.******

I am finding solutions all over the web, I have been searching for hours. However the people that are asking understand Ubuntu, so the steps how to get to and apply the solutions are never discussed. I convinced a friend to convert to Ubuntu from Winblows and I can't get the USB wifi stick to work. I found a solution that sounds like it would fix the problem, I just need help with "Linux for dummies" help:

"I have the same issue here (UQAM), it should have a certificate but, it does not. When you connect for the first time, it wont set it properly so, you need to go to /etc/NetworkManager/system-connections and find your connection name, edit the file. You should see this line:

system-ca-certs=true

change it to

system-ca-certs=false"

This is the website I found that from: https://help.ubuntu.com/community/NetworkManager#Editing_Network_Settings_in_nm-connection-editor

Now I know this shows as a solution for a certificate issue, however I've seen other people use that solution to fix the password glitch.

There is no compatible linux driver for this adapter. A Windows driver can be installed this way.

Do this in terminal

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install ndiswrapper-common ndiswrapper-utils-1.9 ndiswrapper-dkms
wget http://wikidevi.com/files/Drivers/Broadcom/bcm4323x_5.10.79.30_XP.zip
unzip bcm4323x_5.10.79.30_XP.zip -d bcm4323
cd bcm4323
sudo ndiswrapper -i bcmwlhigh5.inf
sudo ndiswrapper -m
sudo modprobe ndiswrapper

But it seems that there is no way to connect to WPA secure networks.

The only solution is to replace this dongle with something else, if security is vital. WEP may work, but it is not very much secure.
