Just picked up a new modem... SB6120 Docsis3.
After setting it up through comcast, my link light was blue, indicating 1000Mbps connection.
Set-up was ran through a Belkin F7D3301 router that i had picked up, but the wireless connection speeds were crap, so reverted back to the 4500.
After setting up the 4500 as the router for my system, the light has changed to amber, indicating 100Mbps connection.
Do i need to reauthorize the modem through comcast to get this working again, or is there a simple solution through the router that i am not aware of ?
Thanks in advance !
