Wireless Access

I have a mixture of 93 and 105's AP's on my network with controller 3200xm Is there a way I can force all the access points to just use 2.4 ghz?

The AP-93s are single-radio and should default to the 2.4Ghz band. The AP-105s are dual radio and will provide simultaneous 2.4Ghz and 5Ghz service. If you want to get rid of 5Ghz service on the AP-105s, you can either disable the 5Ghz radio or set it to air-monitor mode. Both of these option are configured in the 802.11a radio profile for the AP-Group.

The 5Ghz band has numerous advantages over the 2.4Ghz band however. I am curious why you want to disable it?
