window 10 local network file transfer broken?

[Wilson Yu]

So I been having issues with my local network sharing with window 10 for a while now, my file transfer speed can sometimes goes from a normal 70-80 MB/s down all the way to 7-10MB/s. The only way to solve it is by resetting the network but it's only temporarily. I have tried to reinstalling windows 10 by fully wiping the drive, reinstalling all the necessary drivers, and swap out the Ethernet cable, but still it happens from time to time... Does anyone have similar experiences with this on window 10? I am running the newest window 10, version 1903. Any help will be greatly appreciated!
