Packet Loss Issues - 300mbps speed now down to less than 40mbps for 5ghz, 20mbps for 2ghz

https://forums.cox.com/forum_home/internet_forum/f/internet-forum/21209/cox-ruining-fortnite-and-live-streaming-experience-with-packet-loss?ReplyFilter=Answers

Saw this post from last year but doesn't seem to have a solution to it. Pretty much experiencing the same thing. Got the COX 300mpbs subscription in March using their panoramic modem. Got my own modem/router - Nighthawk AC1900 C700- 2 months later. Also have another router hooked up to it straight to my room. A month and a half later, I just started getting slower speeds. Reached out to COX support and pretty much told me that this slower speed is caused by the additional router then shifted to that my modem/router is defective. Support then told me to reach out to NETGEAR support for troubleshooting.

Reached out to NETGEAR twice already with a 24 hour gap where they had me 1) change the channel for the 2.4ghz from auto to 11 and the 5ghz channel from 153 to 161 and then 2) factory reset the router/modem then change the MTU size from 1500 to 1472. Also, just to satisfy the issue with the additional router, I removed it from the main router/modem right before I reached out to NETGEAR.

Again, I was running this set up for more than a month and a half before i started experiencing the slow internet issues. Verified that the router is running the approved COX firmware, replaced cables, verified connections -etc. Still to no avail.

Any help?

    Hi Clevertrumpet323, we're truly sorry you're experiencing slow speeds, and I understand this can be extremely frustrating to deal with. Are you able to perform a hard-wired speed test, using the Cox Internet Speed Test tool, http://bit.ly/2VsdGbX?

    I am including an article which provides ways to improve the internet experience and I hope you find this useful, http://bit.ly/2Kq4uR5.

    Hey man, unfortunately anyone who responds to you here is flat out lying to you. You will not get help for this. COX bought faulty hardware that reorders packets to all AWS servers and disrupts gaming, streaming, etc. Bursty UDP packets get reordering, causing you to experience what seems like packet loss. I would know - I'm the one who worked with amazon, epic, and cox to figure it out. The only solution is COX buying brand new hardware, which who knows if they will. Epic and Amazon were super helpful and got customers off COX's back when they released a huge packet reordering update here -  https://www.reddit.com/r/FortNiteBR/comments/awagpo/packet_reordering_technical_post/  

    This specifically targeted customers of the COX isp to allow us to keep playing, although Epic didn't single them out. Unfortunately, the issue has returned. You will receive 0 help from anyone on this forum. I had to make an actual packet loss montage to get help from JShredz on reddit. Your efforts are futile, sorry dude.

    This was one of my 3 posts:  https://www.reddit.com/r/FortNiteBR/comments/9wiwxm/i_made_a_montage_showcasing_the_connectivity/
