Minihub pro gateway

Hi All
My Minihub pro gateway starts as AP. I can connect my mac to SSID: MiniHub-xxxxx. After connecting i can open web gui at and all what i can do is to set gateway to my wifi. There are not any other settings as described on user manual. The gateway connects to my wifi network and connects to TTN. I can not open web gui anymore? How can I connect gateway to any other network, say AWS?
Thanks for any help
