I got the modem in 2 days on prime. Called cox cable and they told me it wasn't on the approved model list and could not do anything for me. Chatted with another cox rep online and they told me I "had" to purchase the modem through them. I told him, he was full of $%^&. Called cox back and gave them the ARRIS model SB6141 which is on the approved list. Gave them the serial and mac off the modem and a couple min later I was in business. Moral of the story, tell them it is the sb141 or an arris like model on their approved list and you will be good to go. Getting the speed I pay for 50mbps.
Lie to Cox Cable about the model number and you are good to go.
