    FWIW there is one major problem with an on-net test, whether it's Ookla-based or not. An on-net endpoint is going to be low-latency to the customer (~ 7ms or so), and *if* there are packet loss problems within the last mile, those will be masked by a low-latency test because the TCP retransmissions will "recover" so quickly. When performing a low-latency test, it needs to be done in parallel with a packet capture to ensure there is no significant packet loss.

    Upload Speed Issue - Comcast

    The problem with our office connection is excessive packet loss in the "last mile," which makes single-threaded transfers max out at around 8Mbps on our 30Mbps symmetrical circuit, unless we are transferring files over low-latency routes (directly from our ISP or from providers whom they peer with), in which case we can hit 27Mbps. It has been a long struggle, but we are in the process of ditching the last mile provider (XO Communications). Our [local] ISP is either going to resell us a Comcast Business 150Mbs connection, or we're going to get that directly. It's a long story in another thread; this is the short version.

    Comcast is screwing me! Please help!

    Apparently this is the newest modem they have. Yet even with my last modem, these same exact results were happening.

    Since you are getting your provisioned speeds with our on-net test, my hypothesis is that the problem lies beyond your equipment. I'm working on finding that "beyond".

    I'm actually somewhat intrigued by the site and what the TMN platform may be capable of. CA3LE, I sent you a PM.

    To be fair, CW found me on another forum and reached out to me just last week. I pointed him here after making this post in hopes of being able to shed some light on the situation. He personally hasn't made any negative comments towards TMN to me.

    glad to hear... please spread the word. ISPs often try to blame TMN, I'm used to it. I'm glad that you didn't take their word at face value. I bet that you are too. Note to others that read this... the people you talk to at your ISP are normal people and they rarely "know it all". Often you will know more about your situation than they do. Use this site as ammunition to keep them honest and get what you're paying for. If someone tells you that it's TMN's fault... tell them you want to talk to the next level of tech because they don't know what they're talking about. Remember, this site has been a trusted resource probably longer than your ISP has existed. Testing broadband is all that TMN does. Really happy that you're running more consistantly, that's what we're here for.

    Hey CA3LE, just letting you know that they finally resolved the isslue. Tech support was useless even with the new information, and it took multiple calls to get them to send a technician out. When I complained, someone changed a setting on the line that made it stop working at all, and tried to tell me it was still working. "We cannot change it back. Your line is good sir!" They even tried to say that if it's not the modem, the testing sites must be at fault, even though other people were getting good results in the logs. Your explanation gave me confidence that it wasn't a problem with my modem, and we were correct. After a couple hours of troubleshooting, working on the equipment outside, and the tech having people on the phone do things like "change the atm path", he finally realized it was a bad line card in the box where the fiber and phone line connect. After replacing that card everything is working again. Here are the new test results: https://testmy.net/compID/992214742650 Not as fast as I'd like, but probably as good as it will get with the current setup. As you can see there are still speed differences between servers, but nothing drastic. Thanks again for this website.
