| Those are good signals. I would not expect trouble owing to your cable connection (the black wires carrying cable signals). So we'll focus on your IP connection.
Okay, do a traceroute and notice your first outside hop that responds, then ping that 100 times and see if there is any loss.
Windows command: tracert www.google.com
linux command: traceroute www.google.com
Okay, first outside IP that answered was 71.111.112.1 so I'll use that
Windows: ping -n 100 71.111.112.1
Linux: ping -c 100 71.111.112.1
This will take under 2 minutes to complete -- the final lines will tell the loss and the delay statistics.
If these are nearly perfect, then that suggests the problem is upstream from you. We should confirm the theory and repeat this test, but this time choose some point further upstream (maybe the 5th hop instead of the first). If we can find it, then we have something more solid to tell Comcast about.
If the first-outside-hop tests were problematic, then I would start by checking everything from the ethernet connection to your broadband modem up to the computer performing the ping test. Change cables, bypass your router (connect your computer to the modem directly) or try a different modem.
Typical issues include a poorly-matching connection between the modem and the cable itself or the device on the other end of it, a failed ethernet port in the modem, a failed ethernet port in the device.
Post back and let us know.
