I found a GL.iNet router that is called the GL.iNet GL-AX1800(Flint) WiFi 6 Router but it doesn't seem to show up on the table of hardware. Why?
Because neither you, nor gl.inet bothered to port it to OpenWrt, yet.
How do I port it to OpenWRT?
I've already tried requesting a OpenWRT wiki account but no one has responded to me.
