It is not my internet provider, all my other pc's and devices download things just fine. I will get about 1 - 2 GB into the download and then my download speed goes to 0 B/s and never goes up. So basically anytime I'm downloading games.

It wasn't working for me until I used the task manager. Once you open the launcher resume the download. Change the throttle speed (100,00) > go to task manager > right-click the launcher and click end task. I should also note that all the other devices that disconnect from internet are using a wireless connection, where as my laptop is using a wired connection. It happens on Steam, Origin, Riot Games Launcher, and the Epic Games Launcher. However, you will have to restart the launcher from the task manager. flush, renew commands and i did a full reset to my laptop. I even turned off firewall completely and that didn't work, i tried the ip config release. Whenever i start a download on epic games, the internet stops working on all other devices that are connected, this used to happen when i downloaded files with torrent, but it stopped happening there itself (issue came back every now and then but went when i unplugged the ethernet cable and re plugged, however this doesn't work with the epic games launcher.) i tried allowing the launcher on firewall, the epic games website gave 2 different paths to use and even after doing that the issue remained.

I have had this issue for a while now but i did not really try to fix it since i rarely downloaded anything from the epic games launcher, however recently i started to use it more and its getting annoying.
