I have several AP 1231 which I want to use with wireless Lan controller. Whenever I try to upgrade the IOS I get the error message 'AP does not have Supported Radio'
Well I know that the A radio(RSM20A) is not supported, but b/g is!(MP21G).
Is it possible to upgrade to LWAP with b/g only? and how can I do it?
Have you tried removing the A radio before running the upgrade?
Remove the A radio and retry, and make sure you are using the IOS to LWAPP upgrade tool.
