CM Errors and Low Upload Signal? CONSTANT low upload speed and random disconnecting

Below is all the info from my router that I believe is pertinent. I currently have the 500Mbps Down and 10MBps UP package. I recently moved to the area from Fiber internet that I used to get 1GBps UP/Down (for $95/month and LOVED IT). Anyhow... I am currently getting 550Mbps Down and 1-3Mbps UP. I have replaced all the fittings and made sure my connections are snug to ensure 10Mbps UP. I am using the Cox provided Panoramic router/modem.

I play games and like to stream. CONSTANTLY my internet is lagging or dropping connection. IF I decide to use a lot of bandwidth my entire connection will choke and cause a disconnect instead of properly throttling me. HELP ME!! These disconnects are frustrating and I am missing my Fiber internet by the day...

Thank you for any input or assistance!
