Can you please confirm that the trunk image you loaded does or does not include LuCi?

OpenWrt default images do not include wireless enable or configured. Have you tried to click the “ADD” button for radio 0 and manually enter the information to configure your WLAN connection. Make sure you select LAN in the Interface Configuration section. There should not be a WLAN there as your LAN port and WLAN are bridged, and the default config is called LAN.

Otherwise you need to post more info for help. I do not think it’s an image issue, just some missing config.
