Connecting to VT-Wireless on a Mac

Many people face problems connecting to VT-Wireless on a Mac. There is an instruction set for this at:

However it is possible that one step is missing (or that in newer Macs, this step has to be additionally carried out). I tried the following and it worked.

• After following the first set of instructions ("The following are required to connect to this network:") at the above link, do this:
• Go to
         System Preferences > Network > Airport > 802.1x > User Profiles
• There should be a profile called "WPA: VT-Wireless" here. Click that.
• There will be options for TTLS, EAP, etc. 
• In this list, check TLS if that is unchecked.
