hAP ac2 change 5GHz to 2.4GHz

Hello,

Simple question, i just bought hAP ac2, and want to change dual ( 2.4GHz and 5GHz ) to dual ( 2.4GHz and 2.4GHz)
Is it possible?
Already search in the forum and google, but no luck.

No, you cannot change it. But you can create dozens of virtual ap for both wireless interfaces.

Note: you can create up to 127 virtual interfaces per physical interface. It is not recommended to create more 30, since the performance will start to degrade.
