I have installed Openwrt 24.10.0 on the X3000, but there is no out of the box integration with the Modem 5G component of the overall router, I don't know how to setup that part to use it with T-Mobile Home Internet, it would be really amazing if somebody can create a step by step guide on how to fully configure the 5G functionality of the X3000 together with all the other required configuration (without having to compile the Linux kernel), right now I can only use it as a regular Wifi router, it will be greatly appreciated, thank you
