Since few days I had a slow internet problem. After diagnostic I find that the problem was the upload speed for my Realtek PCIe GBE Family controller upload problem. Speed Test give me 16ms ping, 32 mb/s download speed and 0.00 mb/s speed. I test my modem and router with another computer and I have 10 mb/s upload speed on the other computer.
I've upgrade the driver to the last version from realtek site (to version 10.3.723.2015) but it didn't solve the problem.
My computer is a HP H8 1020
Thank you for help
