Hi there. I want to use a router and I don't need more than one port, I want to use it for 600mbps symetric sqm. I was thinking of a raspberry pi 3 or four with an ethernet adapter and a wifi usb atenna. Would they be enough to deal with sqm? If not I have a spare mini pc with a core i3 5005u and dual gigabit realtek lan but I think the power consumption of that thing is a little too high. I also thought of a nanopi r2s but I've seen download sqm speeds don't go higher than 450mbps.
I also saw some posts that are similar to mine but they are from 2017, so I think by now there should be some more good cheap alternatives. Thanks in advance.
