This afternoon I ran some additional tests of my DSL circuit and to my amazement I started receiving over 2Mbps down and 600+kbps up. Hmmm so the day after I post the displeasure I have been experiencing for at least a week with the circuit they miraculously resolve themselves. I contacted Covad and cancelled the need to have a tech, telling the rep that they must have done something to fix the speed issues because I can now actually use the circuit. The Line Attenuation according to the Zoom modem still hovers around 47.3db so nothing has seemed to change with relation to the signal strength. Just have to keep an eye on things.

I have been having a lot of trouble with the Covad DSL circuit where the main parts of Vazoom are (other equipment resides on Verizon FiOS circuits). The circuit has even gotten to the point of being so slow that I cannot even watch a youtube video. Typical download rates are about 300kbps down and 600kbps up. My connection is currently provisioned for 3Mbps down / 768kbps up. I have troubleshooted everything and believe the line is at fault. With nothing even plugged into the line and the modem plugged right to the NID I receive nearly 50db line attenuation on the downstream link which is a measurement of how weak the signal has become from the DSLAM at the central office to when it finally arrives to the modem. The roughly 50db measurement I am receiving is not good at all especially given the fact that the central office is within a 10 minute walking distance. I have even tried a couple different modems and changed out cables etc… A Covad technician is supposed to be here Monday although I am sure they will just have to pass the buck to Verizon who can actually do the work on the line with regards to health checks. If they cannot resolve it I am going to be forced to drop Covad.
