CM1100 Modem Not All Channels Active "Partial Service" (COX) Gig Service
Modem: Nighthawk CM1100 Router: Nighthawk RAX80 Hi, I have Cox gigbit service but I only get around 630mbps max (sometimes 590mbps). I logged into my CM1100 modem and it says that the Downst...
- So here is an update and solution.
After calling several times to convince my cable company to make a house call, they finally did. It turns out the cabling in my house was fine. The problem was that they had a "channel filter" device on their outside cable line. It took a few weeks for them to come back with a bucket lift so the they could reach the top of the near by utility pole to remove it. The tech told me they had installed those channel filters a few years back so they can block people from "stealing" or accessing and viewing cable channels from internet-only cable subscribers. But now with Gigbit internet service those same channel filters also block modem channels making internet signals unstable and slow. When I log in to my modem, it now shows it firing on all cylinders (channels). I'm a happy camper. Thanks you all.
Thanks guys. I will be trying all suggestions. By the way, I did see that there is a cylindrical extension type adapter when I checked the cable outside, maybe that might help if I replace it. Also, I was trying if the cable is the new type of high bandwidth cable but it doesn't have writing on it, its only white. The house is older so I wouldn't be surprised if even the cable running from their box down the street to our house was older. Now to convince them to make a house call.
Thanks again.
Thanks again.
Let us know how it goes. Ya time for new updated coax cabling.

How do I get all Downstream Bonded Channels to be locked. I have one unlocked (#32). Comcast says they can't do it, and Netgear says they can't lock it either. Can I do it myself. I'm not much of a tech person, but Netgear customer support recommended I get it locked so I don't loose connectivity. Thanks for your ideas.
