Configuring ethernet connection

Question

I need to connect to my university network which is a bit tricky doing on RPI. I cannot find how to complete the manual set up steps described on uni site , and the app that configures network automatically isnt working. The script looks for CPU architecture and compares it with the following: x86(i386,i686,i486,i586) and x86_64. Although in rpi case it returns error as processor type is arw61.

If you know a way to follow the steps described on manual set-up, or how i should execute the script, please let me know.

Atm I am using raspbian-wheezy although I dont mind switching if that gets me online.

Following is the settings script:

#!/bin/sh

download_x86()
{
    wget --output-document="/tmp/XpressConnect-x86.tar.bz2" http://autoconnect.york.ac.uk//tools/XpressConnect-x86.tar.bz2
}

download_x64()
{
    wget --output-document="/tmp/XpressConnect-x64.tar.bz2" http://autoconnect.york.ac.uk//tools/XpressConnect-x64.tar.bz2
}

export HW_TYPE=`uname -m`

if [ "$HW_TYPE" = "i686" ] || [ "$HW_TYPE" = "i386" ] || [ "$HW_TYPE" = "i486" ] || [ "$HW_TYPE" = "i586" ]
then
    if [ -f "cabs/XpressConnect-x86.tar.bz2" ]
    then
    echo "Running x86 version..."
    export MY_DIR="`pwd`"
    cd /tmp
    tar xvjf "$MY_DIR/cabs/XpressConnect-x86.tar.bz2"
    "./XpressConnect-x86"
    else
      if [ -f "/tmp/cabs/XpressConnect-x86.tar.bz2" ]
      then
      echo "Running x86 version from /tmp..."
      cd /tmp
      tar xvjf "/tmp/cabs/XpressConnect-x86.tar.bz2"
          rm -f "/tmp/cabs/XpressConnect-x86.tar.bz2"
      "./XpressConnect-x86"
      else
      echo "Will download x86 version..."
      download_x86
      if [ "0" = "$?" ]
      then
              cd /tmp
