Upstream and downstream locked to one channel each but internet won't connect
My CM1000 has solid amber LED lights for upstream and downstream, but the internet light is blinking green and I do not have a connection. I have verified with my provider multiple times and they told me that the modem is registered and there are no service issues at my address. This exact scenario has happened a dozen times over the past month and each instance lasts for hours. Today the router has been trying to connect for over 12 hours with no luck. I have restarted it 3 times, and I have tried 3 factory resets in the past without success. Usually I wait hours to over a day for it to fix itself and use phone data, but school has started up and I can't just wait anymore. The modem is refurbished from Amazon, but 8/10 days there are zero issues
Thanks
Thanks

Please post a copy and paste of the modems connection status and event log page.
- Thanks, here is a sample of the log since it's way too long for the post character limit. If the whole thing is needed I can upload it as a file tomorrow.
Also I live in an apartment so I can't access the coax cable other than the wall port, but there are two ports in my unit and they have the same problem.

Like FURRYe38 says, the logs and cable connections help us more.
You can also check your lines yourself. Its always the ISP's first response that "the line is fine"
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.Please post a copy and paste of the modems connection status and event log page.
