I use this network config often. I’ve done this with an AR300, an MT300N, and an AR150. I speculate that every GL.iNet router can do this.
Basically, I configure my router to connect to my main router, and then plug my ethernet-only TV into my router via a short ethernet cable. It’s very easy and natural to configure with the stock firmware. It’s been rock solid too. For me I am very successful doing this with a 2.4 GHz device, but your wireless spectrum situation or bandwidth demands might lead you to a 5 GHz solution.
