I recently replaced my trusty SB6141 with a SB8200 following a service upgrade from 150Blast to Extreme250. I activated the modem last night and all seems good. Getting 290-300 down and low 20s up. My question deals with the3.0---> 3.1 which is one of the reasons for the need to upgrade. My modem indicates a 3.1 signal down (blue) but only 3.0 up (green). Is this something I should address or not worry about it? My router is an ASUS RT-AC68U. I have not made any changes to the router since installing the new modem (if that matters). Thank you.

You won't get a blue light for the upstream as Comcast does not yet offer DOCSIS 3.1 on the upstream channels.
No prob !
