Getting your Nexus 4 onto the LTU Network

I plan on starting out by helping fellow LTU students get their Linux-powered devices access to stuff on the LTU network that's seemingly reserved for Windows users (unfairly so, IMHO). Who else would like to be able to keep their wireless connection secure or print wirelessly? If this interests you, then read this and my related posts.
My second post here is dedicated to my current project: getting my Nexus 4 smartphone to connect to the LTU Network. Typically Android users would have to use the LTU Guest account for wireless access at school, but this comes with disadvantages like not having an encrypted connection and possibly having to sign in with your browser first before you can actually use your connection. This lets you get on to the better, more secure connection that Windows users enjoy.

For reference, I'm using a Google Nexus 4 running Android 4.3 Jelly Bean and a school-issued LTU Fujitsu Lifebook which is running Ubuntu.

The Steps

First, connect your Nexus 4 via USB cable to your laptop. Follow the instructions provided by this blog to add MTP support to Ubuntu so you can do file transfer with your phone (this step might be unnecessary if you are running Ubuntu 13.10 or later, as MTP support is supposedly included by default):

sudo add-apt-repository ppa:langdalepl/gvfs-mtp
sudo apt-get update && sudo apt-get upgrade
Reboot your computer.

Now, connect your Nexus 4 via USB cable to your laptop. Make sure when your phone reports that it is connected as a USB device that you have it set to use MTP, not PTP. The phone should be mounted in Nautilus. Copy and paste the gd-class2-root.crt certificate file into your phone's internal storage using Nautilus. Go onto your phone, then into Settings > Security > Install from storage. The phone should now provide you the following pop-up; ensure that the settings are the same:

Set a password if prompted; this can be whatever you want. I just prefer to use my phone pattern.

Now, open your phone's Wi-Fi settings and look for LTU Network (not LTU Guest, since that is the relatively unsecure one that anybody can access). Enter the following settings, making sure "Show advanced options" is checked at the bottom of the dialog:
  • EAP method: PEAP
  • Phase 2 authentication: MSCHAPv2
  • CA certificate: gd-class2-root
  • Identity: (Your LTU username) 
  • Anonymous identity: (blank) 
  • Password: (Your LTU password) 
  • Proxy settings: None
  • IP settings: DHCP
Connect and done!:)
