Configuring ethernet connection [closed]

Question

I need to connect to my university network which is a bit tricky doing on the Raspberry Pi. I cannot find how to complete the manual set up steps described on uni site, and the app that configures network automatically isn't working. The script looks for CPU architecture and compares it with the following: x86 (i386, i686, i486, i586) and x86_64. Although in Raspberry Pi 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.

I am using raspbian-wheezy although I don't 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
          tar xvjf "XpressConnect-x86.tar.bz2"
          "./XpressConnect-x86"
      else
