To expand, a bit, on what Neil said:
I expect that the Mango works well, but it is limited by a 100 Mbs network connection. That limits you to 100 Mbs.
I got a GL-AR750s (
https://www.gl-inet.com/products/gl-ar750s/), which has 3, Gbit interfaces (read the docs), and that allows you to operate at the full speed that the wiFi is capable of. It is a router, that can connect to the internet through a modem, or another router, using either wired, or WiFi connections. It is dual band (2.4, and 5) which can be useful.
At the time that I got the GL-AR750s, it was the only one that had Gbit interfaces. I expect that more of those things have that now, but watch for it.
