I am typing "ping 12.250.16.25 -t 500" (without quotes) in the CMD line. Getting "Bad Parameter".

No problem, thanks, it's doing it now. How am I supposed to screenshot 500 lines, though?

My connection has been solid for the past day so far. Possible they have fixed the line by now.

Very possible they fixed the line. I peer through ATT as well and from 5pm-10pm my internet slows down significantly.

Would a more inconsistent / underperforming line produce more lost packets and higher ping, or just one or the other?

Looks like you actually captured the disconnect right there and looks like the router.

That's typical for Mediacom occasionally the second hop would respond with an internal 10.X.X.X address. There was actually a security risk I found that allowed you log into any Mediacom's customer modem with the internal modem address on the WAN side. It would also allow you flash firmware via TFTP so you could theoretically flash bad firmware to anyone's modem without actually having a provisioned modem.

It could really be causing a multiple issues, packet loss will attribute to higher pings. If the line is at complicity packets we start occurring bufferbloat (https://en.wikipedia.org/wiki/Bufferbloat) which should be address in Docsis 3.1. Mediacom simply has mediocre network and I think in your case upgrading to a new Docsis 3 modem would be a good start.

You said the replaced some cabling in your house? What are the signals at your modem now?

They gave me a new co-ax with no connectors (last one had like 4 seperate lines connected to each other) but that didn't help. However, one of the main lines in the city was damaged by squirrels. It was being worked on last week and was estimated to have been finished sometime this week.

Downstream Value
Frequency 165000000 Hz
Signal To Noise Ratio 34.3 dB
Power Level 3.9 dBmV

Upstream Value
Channel ID 2
Frequency 29500000 Hz
Power 40.2 dBmV

Speedtest is also giving me good, normals results of 30ms ping and 30 MBPS download. So far no disconnects from what I can tell in the last day and a half.
