Internet and TV problems after Comcast experienced a power outage. (Modem and cable card tuner)
About a month ago, Comcast experienced a power outage that knocked our service out for hours. Ever since then, both my modem and my cable card tuner are having issues. The cable card tuner bounces between have a "weak" or "none" for OOB Lock. However, it still seems to tune channels correctly a majority of the time.
The internet on the other hand is not fine. After a modem restart, I will get good speed for a while, however download speeds slowly degrade over the course of a few days with high latency. Uploads do not experience this degradation. The automated phone service indicates that errors are found when performing a "modem scan".
Looking in to my modem's admin page, I see that a couple of channels seem to be having problems, with one being particularly bad. Considering the timing following the power outage, a lack of any changes in my cabling or configuration, and the fact that both devices are experiencing problems that didn't occur before, I feel like this is most likely not on my end. The fact that uploads continue to function properly would seem to suggest this is not a bad cable or similar issue on my end.
What are my next steps?

After filling out a negative customer satisfaction survey, I finally got someone to take me seriously. The tech visited today and found problems with the cable from the curb to my home. Replacing the cable has resolved the signal quality problems being reported by the modem. Hopefully the degrading performance over time doesn't return.

I called technical support. The rep I spoke to was following a script and told me that everything is fine. I attempted to explain the information I copied/pasted above, but it completely went over her head. The automated service tells me there are "errors on your modem" but her "tests" showed everything was fine. She just couldn't comprehend the highly technical information I was trying to relay. She eventually defaulted to telling me to contact the manufacturer of my router (the problem has persisted through two routers, another fact she wouldn't listen to). Any suggestions for getting in touch with someone that can actually go off script and hear the things that I'm telling them?
