Are you trying to connect the AP to the unleashed controller ? Please confirm the AP mode ?
Factory default the AP by holding in the reset button for 10 seconds. This will reset the APs IP address to 192.168.0.1.
Configure a 192.168.0.x (other than .1) on the PC Ethernet interface: - Go to the start button on your PC and click on control panel. - Click on Network and Internet and then Network and Sharing center. - On the next screen click on "Change Adapter Settings". - On the next screen Right mouse click on the Ethernet adapter and then choose "Properties". - On the next window scroll down to "Internet Protocol version 4(TCP/IPv4)" and double-click, to bring up the next window. - Change the setting from "Obtain an IP address automatically" to "Use the following IP address". - In the next line down enter the IP address 192.168.0.20 and use a subnet mask of 255.255.255.0, and click OK. (Remember to change the auto IP address setting back when done working with the AP).
