Unstable connection with high correctable codewords

I have been struggling lately with an unstable internet connection, and I haven't been able to find a solution yet. I have Blast+ (800mbps), and I struggle to play games online pretty consistently.  I will get massive lag spikes/packet burst that seems to be originating from my connection. After doing some research on the numbers, I have discovered that my gateway is logging a massive amount of "Correctable Codewords" in the CM Error Codeword Logs. Attached will be screenshots from my gateway admin panel. I have excluded any IP addresses from these shots for my safety of course. 

I need some help. No troubleshooting steps I take on my end seems to improve the situation at all. Thanks in advance!

 A 60ish% error rate on packets, even if they were corrected, seems really high. This problem has been getting worse and worse over time, and is now to the point where I can't sit down and game online (Call of Duty, Counter Strike 2, etc) without major lag spikes/rubberbanding
