I have a fairly old router that doesn’t support gigabit. I also have a network switch that does support gigabit. If I connect two devices directly to the switch, then connect the switch up to the router, will the connection between the two devices support gigabit? If I’m understanding correctly the router would just act as DHCP server and give the two devices a local IP address, but the actual connection between them wouldn’t go through the router at all.
RB4011iGS+ I have can do (according to routerboard) up to 7Gbps for less than 200€. I’ve been pretty happy with it with my 1G fiber connection and it doesn’t break a sweat while doing that. Granted, I don’t run very complex stuff on the thing, but for me it can saturate the bandwidth I have available. From the ISP side I could go to 10G, but I don’t have any hardware which could manage it, so I’m not interested (at least for now).
I initially had Edge Router X from Ubiquiti, but it stalled at around 700Mbps, so that thing is now glorified POE switch on my network and majority of the traffic goes trough mikrotik router and it’s been rock solid since installation.
