I've read a lot of people on here having this issue so hoping mine is similar and someone can help. Have had a SB5101 for about a year or so at 2 separate residences. The last house I had minimal issues. Now, a week into our new one my connection is dropping every 10 minutes for about 1 to 2 minutes. I've called Cox and managed to make it to a tier 2 rep but his answer was my config was wrong and he updated it for me. 10 minutes after talking to him, it happened again and it's been doing it for the last few hours. I have solid connection lights on the modem during the outages but have TONS of errors in the log. Here are my settings:

Downstream
Frequency 579000000 Hz
Signal To Noise Ratio 36.9 dB
Power Level -8.8 dBmV

Upstream
Channel ID 7
Frequency 22800000 Hz
Power 41.8 dBmV

And here are the logs:
