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.

  • For clarification it is Ubuntu 14.04, and this is a well known issue. I simply do not understand how to get to and modify the Network Manager. I know it is a matter of command lines, I simply do not know which ones. – Shawn Alan May 30 '15 at 17:52
  • For 'I convinced a friend to convert to Ubuntu from Winblows and I can't get the USB wifi stick to wOrk.' you should ask a different question. Have you found any related bug reports? Note you can [edit] information into your question – Wilf May 30 '15 at 17:56
  • Thank you for taking the time to respond, I am new to the forum and getting under the hood of linux. I have used Ubuntu years ago, and currently I am focusing on Raspbmc. I understand how the command line works, however SSHing XBMC (which is no longer necessary) and using command line to fix this issue that did not exist years ago is a bit more difficult. – Shawn Alan May 30 '15 at 18:08
  • Please [edit] your question and add output of lsusb terminal command. – Pilot6 May 30 '15 at 19:05
  • It looks like this chip is not supported by any linux drivers. The only option is to install a Windows driver througt ndiswrapper. – Pilot6 May 30 '15 at 19:14
  • Would you mind walking me through that? This is the last hurdle to complete the OS install, it sucks to be at the finish line yet still in over my head. – Shawn Alan May 30 '15 at 19:25
  • I made an answer. Please also add output of usb-devices – Pilot6 May 30 '15 at 19:33
  • roy@roy-Inspiron-620:~$ modinfo | grep 9011 modinfo: ERROR: missing module or filename. – Shawn Alan May 30 '15 at 19:34
  • That was incorrect. I want to find out which driver is currently used. You do not need to post all usb-devices, but the section where your device with Vendor=0846 ProdID=9011 – Pilot6 May 30 '15 at 19:37

  • No. Run usb-devices in terminal and post a section about your device. Post it it your question by [edit]. Not here. – Pilot6 May 30 '15 at 19:39

  • It looks like ndiswrapper driver is installed already. Did you install that? – Pilot6 May 30 '15 at 19:42
  • Yes I did, it is one of the things I tried but was not sure if I did it right because it did not solve the problem. I'm nearing burnt out and just want this finished. – Shawn Alan May 30 '15 at 19:44
  • Please [edit] your question and add there iwconfig output. PLEASE DO NOT POST IT IN COMMENTS. – Pilot6 May 30 '15 at 19:45
  • Do not do cd bcm4323x_5.10.79.30_XP do last 3 commands. – Pilot6 May 30 '15 at 19:58
  • After that try to connect to your router. – Pilot6 May 30 '15 at 20:01
  • I made a typo. sudo ndiswrapper -m – Pilot6 May 30 '15 at 20:04
  • I corrected command. Does it work? – Pilot6 May 30 '15 at 20:08
  • The commands entered successfully, however the problem remains. – Shawn Alan May 30 '15 at 20:09
  • What does it mean? Do you see access points in Network Manager? And post output of cat /etc/network/interfaces – Pilot6 May 30 '15 at 20:10
  • To clarify the wifi dongle is "seeing" the router, the problem is when I enter the correct password it keeps popping up “Authentication required by Wi-Fi network” and will not connect. I apologize if I was not clear enough, this problem has been around awhile (since 2013) and I assumed it was well known just not yet addressed by the programmers. – Shawn Alan May 30 '15 at 20:14
  • OK. What is the SSID (name) of your network? – Pilot6 May 30 '15 at 20:15
  • It is "mycci63" – Shawn Alan May 30 '15 at 20:17
  • Try this. http://askubuntu.com/a/457739/167850 – Pilot6 May 30 '15 at 20:19
  • Press "Choose Certificate" and add that like in that answer. Then uncheck "All users may connect to this network" in Network Manager. – Pilot6 May 30 '15 at 20:21
  • I tried going to "General" tab and unticking "All users may connect to this network", that did not work. – Shawn Alan May 30 '15 at 20:21
  • Did you add the certificate? – Pilot6 May 30 '15 at 20:22
  • I don't have the "CA certificate" issue, only the password not being accepted. Also, I'm using Chromium if that makes any difference--I mean that was showing mozilla... – Shawn Alan May 30 '15 at 20:23
  • Can you disable security in your router for a while? Does it connect? – Pilot6 May 30 '15 at 20:27
  • I disabled the password on my router, and it connected. – Shawn Alan May 30 '15 at 21:09
  • You can set WEP encryption. It is better than nothing. – Pilot6 May 30 '15 at 21:14
  • I just ordered a Kootek wifi dongle from Amazon, it's compatible with Linux. In the meantime I'm tethered to the router. – Shawn Alan May 30 '15 at 21:19

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.
