I recently signed up for Xfinity. I purchased the Netgear Nighthawk CM2000 (modem only, no voice or WiFi router included), hoping to not rent the xFi Gateway anymore. Initially, I took out the xFi Gateway and plugged in the Netgear modem.
The indicator lights were all white and looked fine - though the "download" light is always blinking white constantly, while the "upload" light is almost always solid white.
However, I started to run into issues.
This is all sort of strange, because a technician had already came in about 2 days ago to set up the xFi Gateway, so no other coaxial connections should be loose or anything like that.
I had some more "detailed" issues? Definitely not sure if these could be fixed by a technician or not.
I'm sort of getting desperate at this point, because I had double-checked to make sure I purchased a compatible modem for Xfinity, and I've read other stories (some on them marked resolved and others not) on how some poor souls even went out to buy duplicate modems (in case there were defects) or entirely different modems to no avail, only to find some issue that couldn't be fixed by doing what they did.
Solved! Go to Solution.
Did you do self activation of the new modem? did you look on the internet status page i your account to see if it reports issues? You may have to have a chat rep activate your modem properly. I ran into this on the xFi, it worked but poorly after self activation, site reported issues, called rep fixed in 5 minutes easy peasy.
Ok, so things were resolved today. A Comcast technician had to come in.
Anyways, I'll marked this here (even if there's no real "solution"), in case if this could help someone out there.
