Your levels seem a little low at 2 -2 and 74 -5 this means your quam is usually 10 db below your highest analog carrier depending on your MSO and whether or not they are running 64 or 256 quam downstream. With the levels you provided and am pretty sure that your docsis carrier is borderline or even out of the specified window. Your modem is probably receiving low and transmitting high causing dropped packets. You need to escalate your concerns to the local technical supervisor and tell him/her that you want a maintenance tech to come out and certify from the node to your house and to provide you with some MER and BER measurements. If the downstream is 256 quam your MER needs to be between 32-38 with a tight grouping and your Bit Error Rate needs to be E-9. Click on start go to run and type in command. Type in ping yahoo.com -t this will start a continuous ping to yahoo.com and in order to stop the ping for your test results hit ctrl c once you have let it ping for a while. Depending on your to the server will play a role in your ping response times but you should not see ping responses of more than 50ms. Yahoo is huge and is consistent so I use this site daily as I deal with the same issues and customer complaints day in and day out. A good tech with a good meter will solve your problem. You will need a tech out there with a DSAM 3500 or 6000 or a Hukk meter in order to read the MER and BER. In these days of bandwidth you need good tools to read what your packets of information are doing. Some of the MSO's do have congestion problems with specific line cards and work every day to balance the amount of active modems per card on the CMTS chassis and the goal is to be below 200 modems per card.
