Ok, starting to think I need a new little device for my pfSense. I was thinking of going OpenSense and buying one of their devices to support the project.
Regarding my switch, the ports where my Rukus APs are connected are showing 1000M on the interface. But I think a step by step testing is what is needed as suggested above.
Any thoughts on a good little fanless device that I can use as a pfSense machine that has a resonable CPU. I would just swap the SSD from my curent device to the new one and it should all work nicely.
