I have had the gigabit service for about a month now and over the last week I have had intermittent internet connection. The modem has restarted several times. There are no splitters in the connection path. See the signal levels below. I have a technician coming out tomorrow.
What exactly should I be asking the technician to check? I don't want to get into the situation where they start blaming the modem because this is an intermittent problem. When I first had the service installed, they told me I had to lease a comcast modem, I don't want to get in this situation again, so let me know if there are specifics I can ask.
Please re-read my second sentence in my last reply to you. As stated, checking the return path for integrity should be an automatic part of their troubleshooting. Good luck ! Post back with how things turn out.
