I called Comcast and asked them to test the line. They did a ping test and found total packet loss. The modem test came in at @66.7 milliseconds. Comcast said that was very good. Now I am totally clueless what to do. They suggested deleting temporary internet files which I did. They said if that didn't work there is something wrong with my computer. I know enough about computer hardware to be really dangerous. I did the broadband speed test several times. Currently the download speed is 4393 Kb/s, upload speed 1427 Kb/s, latency 20 ms. There is a warning, "ISP upload compression was detected. Your upload speeds may be inaccurate." When I talked to Comcast I told them what the broadband test results were. I was using the NY, NY server for the test since I'm in NJ. The line quality test I couldn't access not being a member and haven't figured out yet how one becomes a member. All suggestions very much appreciated.
I did the Trace Route test and it is timing out after hop 12 and 14, with hop 11 being Chicago going west, actual timeouts being hop 13 and 15. I called Comcast again and they are going to send out a tech on Sunday after I told them about the timeouts. They did a 100 packet test and it was timing out around 80. Don't know why I'm getting it after 12 hops. My modem was replaced about a month ago but that was mentioned. I don't know if that would have an impact or not, it could be defective, who knows! Thanks for the suggestions.
do you still having disconnections, if you connect your computer directly to modem(with no router in between)?
I had similar problems with Road Runner in 2006 and 2007: frequent disconnections, over 75% package loss in the ping test, tracert timed out before reaching the designated IP address, etc. After tons of phone calls and a lot of testing, Time Warner Cable ( NY ) found that I had signal problem ( too high ) in 2006. It was fixed by adding one extra splitter. Then, I experienced similar problems in June 2007. It turned out that they forgot to give me a new cable modem !!! (The old one no longer worked due to network, hardware upgrade, etc.) The internet connections to IB have been rock solid since then.
