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.
It’s a bit different to work with than “usual” brands, but they have all the features you could ever hope for and then some and with my experience over the years they’ve been very reliable and stable. They have a bit odd models around which have only few 1G ports and the rest are 100M and things like that, but I’ve been really happy with the 4011 I have.
The model I have now runs at about 40C and it’s been on the edge of my network for 4-5 years now without any issues.
