Connecting to Wireless@SGx using Ubuntu Linux

Singapore's island wide wireless network Wireless@SG provides encrypted and unencryped Wifi access. Unless your are a fan of being a Firesheep target, you want to use Wireless@SGx with encryption. Singtel provides detailed instructions for many platform with the unsurprising absence of instructions for Linux. So here you go:
  1. You will need the certificate they use from GoDaddy. So go to their certificate site and download the "Go Daddy Class 2 Certification Authority" in DER format. Note down the SHA1 key for the file: 27 96 BA E6 3F 18 01 E2 77 26 1B A0 D7 77 70 02 8F 20 EE E4. Optional (but highly recommended): open a terminal and check the checksum of your download: sha1sum gd-class2-root.cer
  2. In your network manager applet connect to Wireless@SGx. You will be prompted with "Wireless Network Authentication Required"
    Wireless SGx settings
  3. Fill in the form:
    • Wireless security: WPA & WPA2 Enterprise
    • Authentication: Protected EAP (PEAP)
    • Anonymous identity:: leave empty
    • CA certificate: gd-class2-root.cer (The one you downloaded in step 1)
    • PEAP version: Automatic
    • Inner authentication: MSCHAPv2
    • Username/Password: Your Wireless@SG credentials
A little embarrassment for SingTel: The registration page (at of today 23 March 2012) uses an outdated https certificate.
As usual YMMV

Gravatar Image1 - @Xinex: Your eMail isn't working. When you use nmapplet there is NO wpa_supplicant.conf file. All information is stored in gconf. And it isn't different from what is in the dialog.

Gravatar Image2 - I don't use any GUI tools like networkmanager to connect to the wireless network, can you post the details of your wpa_supplicant.conf file containing the configuration entries needed for Wireless@SGx so that I can test it out on my notebook running Mandriva Linux?
