If you have slow download speed due to connection issues or because there is a speed limit applied on the hoster side, I can recommend to buy and install a cheap raspi 3 with some extra ssd space. All you need is a remote connection (SSH) to the raspi, and then you can copy&paste the download URL to the pi and use wget to retrieve the file. Whenever i download something from one of these free file hosters I use this approach, and then it doesn't matter if i try to pull a 6gb file from a source with a 60 kb/sec bandwith limit. The Pi4 draws around 5W, if you can get your hands on a Rock64 you can build a system which only uses 2.5W
