I've done all these to get my computer to play fortnite smooth. My other games played fine by old settings but fortnite wasn't playing smooth and was kicking me.

modem/router reset: unplug for 1 minute, plug back in let it fully start up and then plug in router.

badmodems.com shows you modems that cause issues with your internet. make sure you don't have any on list if you do save up for a new one or rent from isp.

look into ddwrt and flashing router to give you more control of your internet. go to dsl reports and check your internet for bufferbloat by doing speed check. bufferbloat and using ddwrt can help with that.

drivers: make sure all drivers are up-to-date exception to graphic driver make sure it's 1 prior to latest

make sure all hardware is working by testing each part if you can.

Google dns was mentioned on epic tech page by fortnite dev.

This is a lot of tech trouble shooting to play fortnite.

Hope something helps for you guys.
