Internet upload speed dropping.
My internet upload speeds are usually 20Mbps. But around 5-10pm they "magically" seem to be dip down to less than 1Mbps before going back to normal. Even during the day my download and upload speeds ...

Does the upload speed seem to be tied to high peak times or the sun going down? Also, what model and router do you have? Does the problem happen if you are connected direct to the modem? It sounds like maybe that is what technician did? If they saw the correct speed coming out the modem, that would place the fault on your router or network. If so, that would be a chargeable appointment because the problem isn't with in Cox's responsibility. They only cover to where the coax connects to your electrical ground. I will be able to suggest troubleshooting steps once I know more about the issue and your setup.
I'm using a new Netgear CM500 modem and R6700AXS router. They're both new items bought after the problem started. The problem only seems to show up around 5-10ish pm. It can sometimes extend to even 11pm. I've never noticed any other time frame that I get really bad issues with the internet but I can't say I've been home during the day to notice it. I've even plugged in my laptop straight to the modem and still get the same issue with my internet.
You bought a modem recently and it's only DOCSIS 3.0? DOCSIS 3.1 is the standard these days and there is talk of some areas moving to DOCSIS 4.0 soon. Heck, DOCSIS 5.0 is even in the works in the labs. What DOCSIS 3.1 gets you is OFDM and OFDMA channels. OFDMA specifically gets you more upstream bandwidth, which helps with upload speed congestion. On top of a lack of OFDMA, the CM500 is a older DOCSIS 3.0 modem, with only 4 QAM upstream channels. This further limits bandwidth. Not saying that is what is causing the problem, but it doesn't help.
Can you post your signal levels from 192.168.100.1? Specially the upstream levels. See here for more info. Also, how does the coax get from the pole/street to the room the modem is in? Any splitters/amp/filters?
Last, were you getting slow speeds when the technician was out, direct to the modem? If so, what did they say was the reason?
I'm assuming you mean upstream bonded channels? I can get a new modem but i chose this one cause it was all that i really needed for my speeds. As for the coax leading from the street to the house I have no idea. I know there's a box on the side of my house when the tech came out and worked on it. It leads into the underside of the house down into the basement furnace room. I was not getting the slow speeds when the technician came out. He put an extra item connecting on the connecting portion saying it would help with noise from my neighbor I think?
