My internet connection keeps dropping all day.

You'll need to be more specific because "internet" problems could be anything:  device to router...router to modem...modem to Cox.

What's the makes and models of your router and modem?  You should also post your signal levels as per Mouth's instructions.  You should create your own post because this one is almost 3 weeks old but if jungleBeats returns, it'll be all your troubleshooting.

Update:: There's been Cox trucks in my neighborhood for 2 days in a row now, once down the street - yesterday on my street; both times I saw them working in those ~junction boxes/towers. Once the Cox truck was gone yesterday (he was parked maybe 3-4 hours) my correctables and uncorrectables have been at zero (except for

with minimal connection issues. My Cox appt. is today, my powershell script shows only 2 short disconnects from internet over last 12 hours so big improvement already.

I took so many screenshots, I gathered common issues: 

Common downed channels:
* 783000000Hz
* 789""
* 795""
* 801
* 807
* 813
* 819,825,831,
* (channels between above and below are usually up, but ~28 SNR)
* 939,945,951,967,963,969
* 3000 (ODFM PLC)

In each case, SNR for all other downstream channels below 28, from 45 typical. Listed channels above all stuck at 0 SNR

So frustrating when I need to reset my modem 4 times to watch a single movie over 2 days.

For future reference, emailing Cox at the provided email address was much more successful in getting a response (as opposed to the Tier-1 call-center people who just say it's my fault/problem). I emailed I was going to pull the cable from the box to the street if they didn't respond.
