I managed to figure out it will only do 10/100 and I guess some models do 10/100/1000. I'm just glad it works so when I get an extra computer to fix I don't have to keep unplugging and plugging back in the CAT5 cords and wearing out the heads. Also I just hated setting up my old router and making it act like a switch by shutting down DHCP and changing the IP address so it doesn't conflict with my main router. Now I just plug it in and it's good to go.
Actually the really funny part is once the unit starts to get warm the scent from the side vents smell like the local hardware store or Canadian Tire. LOL
But still there is no way I will ever use all 24 ports at the same time, mainly 3 at the max.
Here are some pictures of the unit.
