  1. Now I'm having the same problem again after two months...
  2. They finally seemed to have resolved the upstream issue. There was line noise coming from nearby locations that they resolved.
  3. Well it's not doing too much so far because these network people are lazy or incompetent or both.
  4. Apparently the FCC actually does something if you report things to them.
  5. I know is the tap itself is in a closet on the side of the condo next to mine and the pre-wired RG59 coax runs directly from there to my house. The heavy cable (don't know what it's called) that feeds the tap is coming from underground (or maybe an amp first?) I think. There are no telephone poles in my neighborhood. Last night they ran a temp RG6 line directly from the tap to my modem to see if there was any difference. There wasn't. So it must be an issue before the tap.
  6. Yeah I'll have to take my computer over there and check it out some more. Seems like this may have something to do with temperature fluctuations and the copper lines. The issue goes away when it's warm out and occurs again when it cools down. The past couple days I've had the problem 24 hours a day and it's barely gotten above 70 degrees. We'll see if it gets better at all in the next couple days when it's supposed to be warmer.
  7. My brother has Comcast and lives on the other side of town. He did the pathping to the same comcast server and got 0 lost packets...
  8. Another upload to YouTube... https://www.youtube.com/watch?v=40moQhc0tk0&feature=youtu.be
  9. Strange. I was figuring they might be just dropping ICMP packets because they're not high priority but you didn't have any lost. Here's the test to the Comcast speedtest in San Jose. I'll run another to the gateway.
  10. So here's the pathping to the Comcast speed test IP. Not sure how significant this is. ComcastSpeedTestIP.txt
  11. Now Comcast network techs asking how to read the wireshark capture and how it indicates packet loss.
  12. So now the upload speed returned to normal for the time being. It looks like the number of duplicate ACKs are at least double when I'm having the issue compared to when I am not. Also the upload speed hits 24 on the speed test. Here's the vid... That's crap. I feel for you. I've wasted a lot of my time on this when they should be taking care of it. ComcastSpeedTestUpstreamWireShark.mov
  13. Yeah I'm on the 150/20 residential plan. Yours doesn't look as bad as mine. I don't understand it either nor why it goes away for me during odd times (non peak usage periods). I read somewhere that re-transmissions without a lot of duplicate ACKs probably means the packets were out of order when they were received and not packet loss. It seems like mine is definitely excessive packet loss. This is so frustrating! Especially since Comcast is so clueless.
  14. Let's see if they try to deny their way out of this! ComcastSpeedTestUpstreamPacketLoss.mov
  15. What was the problem with your connection, how did they fix it, and how long did it take?
  16. I sent them screenshots of a transfer from my SFTP server at home to a client on my corporate network at work showing the issue as well. I guess I can do the same with wireshark. I feel like I'm being forced to do their job because they're incompetent.
  17. Yes that was during problem time. Here is the same file being uploaded a couple minutes ago during "non problem time." I let it run until 3% instead of 2% like the initial test.
  18. I haven't used wireshark in a long time so I'm not sure what I'm doing. Here's a screenshot of the expert screen while I'm uploading to YouTube.
  19. I haven't tried the pingpath test yet. I didn't notice any difference with tracert. I was thinking about trying Wireshark but I've just been too lazy to try that I guess. Let me try both those things and let you know... Thanks
  20. Yeah it was happening every day between ~11pm and ~2pm the next day. However, the past few days the timing has not been consistent. For example, this past Tuesday and Wednesday i was having the issue at least the whole day and it was still happening when I went to sleep at around 10 or 11. I've tried connecting the modem directly to the computer and I've tried multiple computers. It didn't make any difference. I also replaced the cable modem and have had around 4 techs look at the tap outside, and replace coax connectors & the splitter. They also claimed to have removed some Uverse connection down the street that might have been causing noise. Lately they're trying to place the blame on the other networks that I'm connecting to. The strange thing is that my tests to speedtest.net and the "comcast speedtest" don't really change. I'm assuming those are multithreaded tests? However, my test to San Jose on testmy.net and all my upstream transfers to various networks (e.g. youtube, SFTP client at work (both with and without a VPN established to my home server)) show the drop off for individual connections. ShaperProbe also returns a messages saying the upstream test was aborted due to high packet loss during the time period when I'm having the issue. I also noticed that the speedtest.net app on my iphone does show the upstream drop off so maybe that app is not running a multithreaded test? Here's some more screenshots. There's a youtube test during the issue and one when I'm not having a problem. Also the shaperprobe screenshot.
  21. The downstream is high at +10. the upstream power is 38 which is lower than yours.
  22. Isn't my upstream power level low when I remove the -10db attenuator?
