Example Input: Purchased July 2015 from Blinq. Modem is unreliable. It crashes and for a time will not sync with Comcast network. My experience mirrors the other one star reviews. Comcast now classifies as "end of life" for my level of service (Blast.) I contacted Arris customer support and put Comcast tech on phone with them. Comcast tech told Arris modem is defective. Motorola/Arris refuses to honor warranty because purchased from Blinq. Blinq will not take it back. I will replace this modem with one from another manufacturer. Recommend that no one purchase this modem.
Example Output: Very unreliable. Do not purchase.
