Installed quickly and relatively easily. Comcast "forgot" to disable my old modem and enable this new one over the phone, but the tech that came out got it going immediately. Assured me this modem is great and, after several weeks, I agree. No issues. VOI (phone) is great. Hope it lasts for years, like my old NETGEAR.
Have Xfinity 1.2 gig service. Was using Motorola MB8600 and Asus Wi-Fi router. The most I was able to get over Wi-Fi was 520 when next to the wifi router. Xfinity service came out and verified that the modem was putting out over one gig. I changed to the Netgear 2.5 gig modem as I had added Xfinity voice and I am still using the ASUS Wi-Fi router. My average wifi download speed immediately increased 300 GB to over 700. No idea why but quite happy with the upgrade.
The original modem we purchased was not compatible with our service. Was able to take out the original modem, setup up this CM2050V, and install in less than an hour. Now able to take advantage of the full 1.2 Gig internet service!
