2 SSID's but only one will accept legacy clients

Hello all,

 

I have 2 SSID's that serve the same purpose and I would like to disable one of them.  SSID "X" was created a while back and SSID "Y" was done with our clearpass integration.  SInce then I have upgraded most of our AP's to 315's and our controllers to 7210's.  One issue I am seeing is that older devices primarily Mac laptops and IOS devices will not connect to ssid "Y".  They usually are macs running older OS X softare like 10.5 or 10.6...perhaps 10.7.  If the hardware will support an OS X upgrade to the latest or one version older it works fine.  I had an iPad 1 in my office one day and I could not get it working on the "Y" ssid.  I am not sure where to start but here are my SSID configs of what is different on them.  I am aware there are a lot of settings and these might not even be what is needed so please let me know if you need more information.

One by one, change things to match the X SSID and see what fixes your issue.
