Let me make life easier for you. I am a network engineer and communications specialist with over 16 years at Cox Communications.
If you are having slow internet and packet loss, there are a NUMBER of reasons why this can happen. Since I have a good modem, and an ethernet connection, here is my speedtest - Which btw I will run at 7 pm, and tomorrow, at several intervals and post here.

I am in Virginia beach, and the test ran to Fairfax, Va. I am on the 500 down, 50 up speed and as you can see, I am easily getting what I pay for. Of course, my equipment is up to date, as is my computer.
So - Instead of believing what the OP posted, There are some things that can help if you are not getting good speed and you are having issues. I am in the forums quite often, and will help you out as much as possible. You would be surprised how easy it is to fix MANY issues.
You aren't wrong, but OP's post was 4 years ago. Cox has made a lot of infrastructure upgrades since then that improved performance. Cox installed fiber in my neighborhood. The node is about 100 feet from my tap. My speeds are virtually identical to yours.
I am 100% positive that you and your associates are scamming people. I have found a loophole however. Stop your plan every 3 weeks or so and then restart a new one. That's the only way to get good wifi. Otherwise you get the best wifi in your neighborhood or hood when you first join for a couple weeks or even a month some times and then it drops to 1/10 the download speed, latency goes up 1,000%, everything flips on a dime. I'm not sure if the motums are only good for a couple weeks then brick causing this or what but I cancel and resign for wifi every couple weeks, never change wiring or nothing and jt has solved the issue. Before that I ran into this issue every one of the 5 times I signed up as I kept switching between providers. Now the problem is solved.
You and your associates? I am retired my friend. I am a network engineer, holding certs in Novell, Micom, and Bay Networks, as well as in digital and analog communications and other disciplines. My last job in the military was AIS security at NSSF New London.
Additionally, my speeds are https://www.speedtest.net/result/16429499277 for my desktop computer, and my WiFi 6 Laptop without having restarted my modem, or my router, (CM2000 and RAXE300), https://www.speedtest.net/result/16429509520 for my laptop. It's been so long since my equipment was restarted I couldn't tell you when it last was. My plan I am signed up for is the 500 down and 50 up plan.
Novell certs? Oh wow, were you Master CNE by chance?
