Legacy777 Posted January 30, 2016 CID Report Share Posted January 30, 2016 (edited) Hi everyone, I am looking for some help or input on troubleshooting my slow upload speeds. Some background on my issue; I am in the Houston, TX area, have Comcast, and I currently have the 25 mb/s download and 10 mb/s upload package. I've had cable internet at this address since 2003 with Time Warner before Comcast bought them. Overall I've been happy with the service despite a few issues here and there. When Comcast blocked port 25 I was forced to move to their business service since I run a server do work out of my house. Because of this I use upload speeds a lot more than your normal user. When I moved to the business service the package level I had was 19 mb/s download and 3 mb/s upload. I had been on that package for over 2-3 years and it was fine for my needs. Beginning this past November (2015) around the middle of the month my upload speeds just hit the floor (400-500 kb/s). When I called I was told there were a lot of outages in the area. I continued having issues and had a tech come out in early December. He checked everything, verified all the connections and lines, and told me that there was noise in the line which was affecting the upload speeds. I also found out that Comcast added a fourth upload carrier signal around mid-November. I was told by a couple of the techs that they knew there was noise in that frequency range. I have had several techs come out, and that the maintenance department has been working on the lines to reduce the noise. However, I still have intermittent times where my upload speeds are below 1 mb/s. Even those times that it is above I find that the speed is very inconsistent. Yesterday morning I had a very short period where speeds were good, browsing was "snappy" again and upload speeds to my off site server were good. The techs have escalated my issue to their supervisor and I've been communicating with him and they are trying to resolve things. Where I'm at now is that they've come out and run speed tests from Ookla or their own speed servers and speeds were fine. So I need to try and explain those test aren't an accurate representation of my speeds. I currently have my own modem, a Surfboard SB6183. The modem is new as I replaced an older surfboard to eliminate that as a possible cause. My normal network runs through an older Linksys WRT54GL router running dd-wrt firmware. However I have direct connected multiple computers to the modem to see if that affects speeds and it doesn't; I still get the same results. If the techs tell me they've done everything they can do, then my next option is to try one of the Comcast modems as a last ditch effort. If that doesn't work I'll have to find another ISP because I can't continue to deal with the intermittent slow uploads. It's affecting my work, and I've spent a lot of time trying to troubleshoot and don't seem to be making any progress. If there are any diagnostics or tools I can use to try and help pin point the issue to pass along to the Comcast techs I would be extremely grateful. Here are my test results for the past 90 days. https://testmy.net/stats/?&t=u&d=01302016&x=90&l=25&q=Legacy777 https://testmy.net/stats/?&t=u&d=01302016&x=90&l=25&q=Legacy777 I've also attached my modem status, event log, & configuration pages for review to see if there's anything in there that may be useful in troubleshooting my problem. Any help would be extremely appreciated as I'm nearing my wits end.
