I keep losing connection to connected franchise

I swear to god I can't play this game anymore, I can't play any game mode relating to online gaming comfortably, literally everytime I play a game, ONLINE, i'm either constantly waiting for a disconnect, or it disconnects right away. I swear if someone mentions a Internet problem relating to my WiFi router, I will sue someone. At the moment I am watching a 4K video on my computer, watching Psych on amazon prime video, and about 10 total devices are connected to the router, and no problems what so ever, I only play madden when there are very few devices being used on the router. I tried all the workarounds to avoiding this, and it ain't working. The youtuber MrHurricane is also having this problem. I can't even give anyone a code because it's because of "The EA servers are currently down" and literally 5 seconds later I'm back on the servers.
