Download speed fine. Poor/intermittent upload speed.

Hi, Recently I've been experiencing issues with my upload speed. The download speed is fine. Sometimes when I run the cox recommended speed test, I'll have around 8Mbps upload, and 30 seconds later...

UPLOAD SPEED POOR PERFORMANCE

    Just to give some semi-closure to this, I've still been having the upload issues with Cox. Unfortunately I really need a consistent upload, so I had CenturyLink come out and wire me up so I could test both services in parallel. So far, the CL service has performed very close to the advertised speeds and I haven't had any upload problems whatsoever. Meanwhile the Cox upload is still bouncing all around the place. Such a shame, been with Cox for a long time now but it looks like I'm going to make the switch to the service that works. Here's the latest snip of the Cox upload speed jumping all around. 

    I've found testmy.net upload test to be very helpful as a sustained upload test just FYI for everyone. Choose the upload test at the top and I do a manual size that's larger to see the consistency.

When or if this happens again please run a few traceroutes one on google, twitch and any other site so we can take a closer look.

Thank you for replying. Is there a specific program/tool/site I can use to run a traceroute?

        Here are some basic steps on how to perform a Traceroute, and please perform this while hard-wired directly to the modem:

        1. Open a command prompt window using one of the below methods.
        a. Click the start button and type "command." Wait until "Command Prompt" with a black box appears. Click it.
        b. On your keyboard, press the Windows key and R key simultaneously.
        2. Type or "tracert www.google.com" without quotes or "tracert IP Address."
        3. Once the trace completes, press CTRL-A. This will highlight all text within the Command Prompt.
        4. Press CTRL-C. This will copy the text to your clipboard.
        5. Paste the text into a Notepad or Word document and send it to us.

        Please also ensure there are no loose or damaged connections between the wall and the equipment. -Kevin M. Cox Support Forum Moderator
