It doesn't look as if Microsoft has fixed their Samba upload problem with win10 yet.
I try a Win7, another laptop but HP, with the same network card (different driver).I disabled the LSO and everything works perfectly... upload and download...
This is what I had to do on my laptop Win7. Disable LSO. Why do you want to keep it enabled?
