All Arris devices are reliable, and if you are experiencing any issues with the modem/router, I would suggest visiting www.arris.com/consumersupport for further assistance.

Also, could you let us know the product model number?

Left a lot to the imagination. 

Are you trying to buy one? 

Looking for support on one?

Looking for thoughts? 

Sorry about the lack of info but yes I am researching buying one to replace my rental unit. My main question is support after purchase since Xfinity won’t be providing any support. Also if any has input on the reliability ie. failure stats, replace process and speed and ease of installation. Thanks
