    I had a service call today. The tech found that the line from the pole to my house was causing over 10 dB of downstream signal loss, and also found an issue at the pole related to upstream power. He replaced the cable and opened a maintenance ticket for the other issue, and said it should be fixed in a few days. My signals look a lot better and I'm very happy with the quick response from Cox.

I sent the e-mail yesterday at 12:21 PM with a subject of "Question about modem errors". Please note that I don't use Cox for my e-mail. Does the e-mail need to be sent from a cox.net e-mail address in order to reach you?

      Very strange. I checked the logs on my mail server and I don't see any traffic to/from cox.com other than the message I sent yesterday. I'm not seeing any incoming messages or connection attempts. Could you please re-send the reply?
