As far as I can tell, the Mozilla implementation always returns Infinity 
for .bandwidth.

And this is perfectly compliant, since the spec says:

     The user agent must set the value of the bandwidth attribute to:

         0 if the user is currently offline;
         Infinity if the bandwidth is unknown;
         an estimation of the current bandwidth in MB/s (Megabytes
         per seconds) available for communication with the browsing
         context active document's domain.
