Poor Upload Speeds

Hi,

I subscribed to Cox two weeks ago on the premier package, did the self-install with my SB6183. Though it took them sometime to provision, I got it working. The download speeds was suffice but upload is very poor. I averaged at 5 Mbps (it should be at least 10), sometimes it was as low as 1, and other times it reached 8-9 but it was still very poor. Even at 8-9 mbps, FaceTime./Skype was horrible. I contacted Cox and they told me they noticed packet lost so they advised I have a tech come over. 

The tech said the signal was strong and stated that Cox just says they noticed packet loss when they don't know how to resolve the problem. He did replace the coaxial connector though. After he left, I called Cox to upgrade to ultimate. My download speed jumped to 320 but upload is the same. I contacted Cox again and they told me it was packet loss and that I need to invite a tech yet again, just 15 minutes after he left!!!! 

I also ordered the SB8200 which will arrive tomorrow, will that make a difference?

Video from my Ring doorbell: https://ring.com/share/3165785342 you can see the upload lag! Router (AirPort Extreme) is 5 feet away.

This is very frustrating!!!

    Can you try signing into your http://www.cox.com account and testing your speeds there both with and without the router?

    Ran the speed test, results aren't good. 

    I also  got the SB8200 hooked up, it took Cox an hour to provision it. Went to speediest, download is the same (320) and upload is sometimes slightly better at 12 mbps. The tech said their is one packet lost (when he sent 50). So a tech has to come again next week!!!

    Here is the new modem status: https://www.dropbox.com/s/u673lm89yu1repv/Status.pdf?dl=0

    I did this speed test, it was 220 down (per my recollection) and 14 (up). Still not ultimate speeds...

    The Cox tech just left, he was more knowledgable than the last tech and ran some test. He connected his gadget to the modem (it is DOCSIS 3.1 ready) and it provided slightly better speed test results but it wasn't a significant difference. My internet speed is the same. He said that he will notify his supervisor to keep the case open and monitor the connection...not sure what that means.

    He did add something to my modem to lower the signal and here are some updated results. Any feedback on it would be much appreciated.

    Here are some speed test results and other info: Dropbox

    I'm still seeing some packet loss at the modem. It looks like a tech may need to come back and take another look. If the problem is confirmed to exist at the tap servicing the home he/she should open a ticket with our maintenance team to investigate a possible plant problem.

    Did a speed test at the apartment and got perfect speeds! It seems the maintenance they did earlier today resolved the problem!
