A full screen snip of the event log and the cable connections page helps the most for checking the line.
But a few tips for troubleshooting cable coax lines.
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, 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.

Modem isn't exactly where it comes into the house but isn't far from it. It's connected with a high quality coax that's less than 6 ft long. There is nothing in the line from the wall to the modem other than the cable. Also, it has been set up this exact way since we bought the house in Nov. 2019 and has had no problems. ISP is COX cable and I get 250 down when everything is functioning properly. I tried swapping my 2.4GHz channel as well. It was set to auto and using channel 3. I switched it to channel 6. Would have done 11 but my neighbors wifi appears to be on 11. 5GHz is on channel 48.

Your signal is actually a bit hot (high).
Try putting a good quality double or triple splitter in line to cut the power level down.
You should be between -7.5dbmv to 7.5dbmv. You're a ways above that.
- YrokJun 25, 2022GuideOk, I have a 2 way splitter coming tomorrow that I'll put in the line. Strange that too much power would be a problem. Also, I assume the power has been the same for the last 2.5 years with no problem. I'll put the splitter in tomorrow and see what I get.
- YrokJun 25, 2022GuideJust put the splitter in. Didnt bring the power down as much as you wanted but it is better. I also moved the router/modem further from my TV since I have the extra cable length now with the splitter. I'll give it a couple of days and see what I get. I also ordered a 10dB attenuator from Amazon that I'm thinking I'll put in place of the splitter. Thoughts? Attached is the results after the splitter install.
