Hi @jxs457, LuCI needs to be installed as a plug-in package (see Luci is missing on MT1300 - #2 by alzhao) and you will get it as an Advanced link.
Besides the Wireless Network management (which is not controllable and reports missing/disconnected, apparently because of still not available support of the MTK SoC) and the LED Section that seems to have also no effect (see GL-MT1300 LED control instructions for LED control) all seems to work well.
