What is my best option for my Comcast connection:
Buy SBG6580 and bridge?
Seems silly to pay for a router I won't use but the SBG will provide future insurance on the speed and downstream channels. Since it seems the SB6180 is still not available on the market I don't have a lot of choices.
However, I am willing to accept recommendations for a Comcast approved modem as long as it's going to give me top performance and is DOCSIS 3.0.
