Cox says get a new modem?

[Elclid]

My modem is a Netgear CM1000

Yesterday the internet went out, I restarted the modem and now the upstream light is flashing, internet light is off, the other lights are solid green. My dad called Cox, they told him we need a new modem. Does any one know if theres something I can do? This was a 150 dollar modem we got less than a year ago and I don't want to believe it just failed one day. 

SOLVED: I HATE COX SUPPORT

Bought 200 dollar new modem, Still didn't work. Did some re-connecting of my coax cablees, turns out one of the splitter's was bad. We didn't need all the splitters anyway, so i hooked it with a different splitters and like magic it worked.

If it’s less than a year old, then it should still be under warranty.

Try doing it a hard reset/factory reset. Also, connect to the modem directly and check the logs on the modem. Post them here. There might be an issue with Cox and they might be blaming you (Who knows?). Also, see if Cox send a refresh signal. Sometimes a refresh signal fixes silly issues.

Lmk if it's too hard to Read. I also tried rebooting from the website and it rebooted and same thing happened. There's also a factory reboot option. Is that a good idea? I asked Cox to send a refresh signal. They said they did but nothing happened to the modem

Oh I refreshed and got a new one with priority of "warning" and says B-INIT-RNG Failure - retries exceeded

Go ahead and do the factory reboot option. It might help. Try tying the Coaxial Cable tighter. Also, check outside on the side of your home for the box they probally installed. Tighten the cable there also.
