I recently went from 60/10 to 300/40 internet, but i'm only getting 100 Mbps download. Also both my LAN Port only show 100 Mbps in the Status window. Modem is a Hitron CGNV4-EU which support up 500 Mbps and has four 1 Gbps ports. The cable going to my wall unit is a CAT5E, and the wall unit itself is CAT6A rated, from there it's connected with a CAT5E to the PC. Motherboard is a Gigabyte Z87X-UD5H with an Intel I-201 and I-217. I tried forcing 1 Gbps in both adapters, but then it refuses to connect to the Internet.
