Thanks so much AL. The command works. However, there are still some problem. I will come back to them after my business trip. Really thank you for your help!

Hi Michel, I command  "config interface address management 192.168.1.101 255.255.255.0 192.168.1.1" However, it replies "Request failed - Active WLAN using interface. Disable WLAN first" Is that due to my hardware? I don't have switch. I just connect...

Hi Stein, Could you teach me how to "set the interface to trunk on the DHCP Vlan" I really not good at this... Buy this Cisco AP just because I heard that it is more stable....

Hi Mishaaltk, Thanks for your suggestion. I will try that if I still can not make it...

Thank you so much. I will try after my business trip.
