No, it's usually a problem with your connection to Comcast, which supplies the OOB signal over the cable network along with the other signals it provides to you. Such signal problems are often due to poor coax connections or damaged coax cable, usually in or near your home.
If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you can't find the problem or you'd rather have Comcast take care of it, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. If they can't fix the problem remotely (unlikely), insist they send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have their Service Protection Plan (https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device, or anything outside your home, you shouldn't be charged.
So I had comcast come out and they replaced my drop as it was old RG-7 cable. That vastly improved the internet connection and SNR looks great. The cable card went to Success for a moment but then back to NONE. Would the next step be to replace the cable card?

You can certainly give that a try. But your best bet might be to contact SiliconDust and ask their advice: https://www.silicondust.com/support/troubleshooting.
