NETGEAR CM2050V Nighthawk Xfinity Modem with Voice

My experience so far is that the refurbished product worked with outstanding performance compared to my old equipment. When you consider that significant discount for purchasing a refurbished version, the value is very compelling. The challenge was in the installation process. I downloaded the Xfinity app and tried to install myself. The app is pretty straightforward, you enter the new addresses related to the product and Xfinity is supposed to recognize the changed modem and activate it. I tried several times and that didn't work. Next I tried the online support affiliated with the app. The person on the other end sounded very professional and entered the same address info I previously manually entered. We were able to get the Internet portion to activate but not the phone line. So, after about 90 minutes going through these 2 steps, I had a tech support person call my cell phone. She said that the equipment had not been changed in the system. Seemed like a strange statement given that she did not ask me for the addresses of the device. After several attempts to activate the Internet and then the phone line, we finally were able to get the latter activated. All told, about a 2 1/2 hour process...ughhh. The Netgear modem combined with the TP-Link AX5400 WiFi 6 Router offer great performance---couldn't be happier as compared to my dated Xfinity leased equipment. Needed a personal reboot to erase the anxiety from the installation before I could enjoy the new technology however--there is no tech support for this aspect of the install:)
