Nighthawk AC1900 (R6900)

I paid for 1000 mbps which is about where Comcast tested in into the home.  It is coming out of teh modem at 80 mpbs.  Ouch, need to see if I should trouble shoot or return the unit to Costco.

Is it 1000 (thousand) or 100 (hundred) Mbps?

C6900 is NOT certified modem for 1000 Mbps. It can only support upto 300 or 400 Mbps plans on Comcast network.

you will need a C7800 for gigabit/1000 Mbps service.
