Comcast Troubleshooting
Testing Notes:
1) Resetting the modem has done nothing
2) Connecting my computer directly to the modem has done nothing
3) Line test shows some packet loss: http://www.dslreports.com/linequality/nil/2579328
4) Bandwidth tests show normal for local sites and less than 1/10th normal speed from the east coast
5) Surfing is hit of miss. Sometimes the site loads sometimes i have to refresh the page a couple times to get it to load.
6) Steaming video or flash is impossible. Worse than dial up. Its not slow to stream it just stops streaming the middle never to continue
7) Traces are hit for miss. Some work some timeout after 64 hops.
