Post your modem SB6183 modem readings. Downstream, upstream and error logs. Also was the tech at your house a Cox contractor?
There are 3 modem screenshots, ping tests showing packet loss mild example, and an error log screenshot in the album linked
It was a tech sent out by Cox, however they did not appear to be an actual Cox employed technician.
Your downstream power levels are too high. If you are seeing 7 or higher you will have internet issues. The closer to 0 they are the better.
You will see information online reference acceptable power levels for qam256 - 15 dBmV to + 15 dBmV. It just means cable modems are required to support these power levels. These numbers are bogus. If you are seeing 7 or higher they are too high.
Reference the Cox tech that was at your house. Most likely you had a Cox contractor and not an actual Cox employee that gets paid hourly by Cox. These contractors get paid by the job. The quicker they get finished the better it is for them.
I had one recently come to my house and he tried to cut some corners. I asked him countless questions and a lot were work related. He specifically told me he gets paid by the job. He said he looked into getting employed by Cox but he said he makes more money as a contractor but doesn't get the benefits (medical/dental etc) that an actual Cox employee would that gets paid hourly.
