intel i219-V (Asrock Z170 Pro4S) performance on windows 10

[MMacu]

Hi,

I am having problems with my network performance.

If i leave it's speed at auto negotiation it works on 10 mbps.

if i set it manually on 100 mbps? download works nice but upload is as low as 0.03 mbps or it doesnt work at all, i think depending on driver i use (i checked one from intel and one from Asrock site).

I didnt have any problems prior to upgrading my os to windows 10 and another computer in the network works fine with download of arouind 100 mbps and upload around 40-60 (like it should be).

Any help please? If you need any addtional data regarding drivers or anything that could help identify problems just ask i will provide them ASAP.

Best regards,

ok i fixed my problem.

Seems like intel ethernet cards is more sensitive to network cable quality. I changed cable to better and now all works fine.
