I am using a router. But the wired speed i am getting is less than half a gig. Wireless is almost 800mb, I wanted to enable the second port so i could run the router and my PC plugged into the cable modem to help trouble shoot the issue because I have exhausted all options. Calling Xfinity just does not help, I might as well call my 80 year old mum. She would be of more use.
You can't use both ports on it right now, unless you purchase a second IP address, or until LAG is implemented.
As far as your wired speeds, try turning off any extra features such as deep packet inspection, QoS, or DDoS protection in your router. If this doesn't work, then the above mentioned Gigabit Speed Troubleshooting thread might be of help.
What router do you have btw?
