Replaced Comcast supplied modem - works like a champ so far! This refurbished unit is great :)
November 10, 2017
If anything changes with the operation of this unit, I'll update this review. I just got the unit today to replace a Comcast modem/router combo since I have (and have been using) an Apple Airport Extreme router. It was super easy. Just unplugged the old modem, connected the new one and then made a phone call to tech support (Comcast) as I needed to provide my MAC address to them. After a few minutes, they shot a signal to my new modem & I saw the lights flicker and all was well. Then I plugged in my Airport Extreme. I couldn't connect to my WiFi network so after all else failed, I reset my Airport Extreme and then it worked like a champ.
Interesting to note; I've done a half dozen speed tests with the old Comcast supplied modem/router and I would get between 47-51 mbps. So far when I run the same speed test with this new modem I got, I've gotten 56-58 mbps. I saved approximately $20 by getting the refurbished unit (I paid like $44 for it). So now I get to save the $10/mo that Comcast has been charging me to lease their modem.
I hope this little guy keeps up the performance. So far - so good!
