A:
Yes. In fact, we were having issues with our modem and the service person recommended this exact model. It has been great once we got it setup.
A bit of advice, we tried calling Comcast, but they weren’t able to get it setup right and told us it would be ready after 24hours. Almost 36hours later it still wasn’t working. Reached out to Comcast through Twitter and within 20minutes the modem was working. I’d try Twitter first next time.
