Would love to hear how it's working for you. I am right behind you, I had ordered the same part from amazon and came across your post.
I'm particularly unskilled at all this, however it does seem to be working.
It's not even my 'production' machine, it's behind my real, normal DSL router (So I'm running 2 networks, for testing)
The Chromecast, PS5, Switch are ethernet plugged into a 4 Port, Wireless AP / Router / Switch (in AP mode)
It's a GL.Inet 750 wireless router
Several of my devices in the house, are connected to the 750 wireless AP to get internet, instead of, the normal DSL modem.
Laptops, phones, iPads etc
My intention is to see if it falls over and crashes, or if the network connectivity drops out at any point, thus far it's been fine but I really want to run it several weeks first, this needs to pass the wife test, so I can't suffer much downtime or fiddling!
(She's still using the normal DSL modem AP and network)
