Re: Losing connection to matches with good internet (100 Mbps)
Sounds tough what you're going through, @MrBopee. Situations like that can definitely lead me towards the Dark Side at times, let's see what we can do to get that fixed for you.
I recommend the basic troubleshooting steps below as a good starting point. If you're still having disconnections, consider opening up the ports listed for Star Wars Battlefront II. That should help improve connectivity to the servers. There is also an option in game where you can select the server ping site under settings. If you're constantly getting disconnected from a server site, toggle one spot to the left or right.
Keep in mind that if there are multiple devices on your network streaming or downloading content it can slow down connection speed. I'm not sure if that could be the situation if multiple people in the house are streaming Netflix or downloading at the time when this happens.
