I apologize that it has taken so long for us to respond to this suggestion. I'm not sure how it slipped through the cracks, but will investigate to make sure it doesn't happen again.
First, let me explain that the wireless connections in the library are a part of the campus-wide wireless system administered by McMaster's University Technology Service (UTS). The library works with UTS on a number of technology related issues. In order to try to address the problems you were having we're going to investigate with UTS to see if there is anything we can do about the multiple names for these connections.
As a side note, we have an IT Help service available at designated times both online and in person at Mills, Innis and Thode Libraries. For more information about that service, visit this link http://library.mcmaster.ca/it-support
Update: Digital Technologies Development Librarian, John Fink, contacted patron via email. UTS was consulted the multiple SSID issue appears to be operating system dependent. John invited patron to visit the library so he could look at his machine.
