I called Comcast to complain again. Had a tech scheduled for the next day. Before the tech arrived, I got an automated voice mail that said this: "Hello, this is Comcast. We are calling to advise you that our technicians identified an issue in your neighborhood that may have caused the service issue that you reported. We would like you to know that this issue has been resolved and that you may no longer need the service appointment that you have on Wednesday, February 10th between 4 p.m. And 6 p.m. If your services are restored and you no longer need your appointment, please call us back at 801-964-7576 to cancel your appointment. Thank you for choosing Comcast." This is what comcast considered as resolved issue. https://imgur.com/1QxKmVF When the tech arrived, he check the signal, node, the outside line. He said everything is fine. Then I show him the live high ping, packet loss result. He went outside again to check the line again, and said there's high voltage in the line. Recommends that I hire an electrician to ground the house. So I said eliminate the voltage by plugging the modem into a backup battery, remove all the ethernet cables, and use a laptop to test. Same result, ping spikes, and packet loss. This is happening through out the whole day. https://imgur.com/KZg9fum As I am writing this post, I got a text from the tech saying there is intermittent noise interference and network team are working on tracking it. I hope they fix it, but it's comcast, so my hope is the same as winning the lottery.
