Can't seem to upload that log. Not sure what I'm doing wrong.
The log entries all are critcal 3, Error 4, and Warning 5, Notice 6
These are the most common messages from the log:

The cable company replaced all the cable and connections from the telephone pole to the modem. When that didn't help I bought this modem several months ago hoping it would help. There is a new splitter that I will bypass as a test.
The modem is 6 feet from where the cable enters the house.
When I tried to send this post I got message saying that this site had removed invalid HTML. Not sure what that is about.

the log is indicating line issues but it helps to have the cable connections page as well.

got channels 1-10? channel 11 has errors and your power levels are pretty high
- JammoOct 16, 2021Tutor
Thanks plemans,
Any thoughts on resolving these issues? I will research further, but can you give me a ballpark for what power levels are acceptable and how I might change them?
