I'll stop preaching the Cisco gospel soon (well, e.g. Aruba would probably also do just the same thing :-) ), but in a WLC-based solution, there's a setting to just refuse the first few associations on 2.4 GHz if it detects the client is 5 GHz capable. It's a hack, but it pushes people over to 5 GHz quite effectively. /* Steinar */ -- Homepage: http://www.sesse.net/
