Correct firmware version for Cisco DPQ3212?

I have been having nothing but issues with this modem.  It cuts the internet out on and off all day and night.  It is not fully lighting up. The on line, and TEL 1 light should be lit up as I have the telephone connected as well.  The link button is constantly flashing. I rebooted everything on my end and had cox on there end reboot as well.  It helps for 10 minutes then cuts out again. Is this a possible firmware issue? 

Thank you for any help in this matter.
