Of course you can:cool:

I just got one of this EAP product for my office currently. And I find that there are a lot new things/concepts about the EAP series we need to learn.

The firmware 20141107 is developed for cluster mode. You can check FAQ772 to learn more of cluster mode.

To configure a specific EAP, navigate to Cluster tab --> AP list, and click the Edit button at the target column. Then a new box will show, where you can configure the selected EAP’s settings separately.

As the FAQ says, we can edit the individual settings of a specific EAP including the IP address.

There are other FAQs on the support page of the product in TP-LINK's new websites.
