Comcast Corporation Complaint - DSL Service not as advertised
Comcast publishes DSL response times that are inaccurate. We've spent hours on the phone with Comcast about our slow service only to have them point fingers at our router, or other service providers. What we learned was that if you ping a site such as Apple or IBM, or Costco, our service times out. But if you ping one of the national organizations who report Comcast service, the ping goes through really fast.
If you're having a problem, try this test yourself. Go ping any site and see what the speed is, and then ping Comcast directly.
