Hi all, Im not sure if this is a motherboard lan port issue or a Windows issue. I recently upgraded my internet to a 1000/100 line and while the download speed is perfect on my pc (get about 900mb/s), which is connected via lan, my upload speed is only about 30mb/s. When I connect my laptop via the same lan cable I get the full 100mb/s for upload. I have enabled full 1gb duplex in adapter settings, this did not work. If anyone could please help me with this issue, it would be greatly appreciated. Thank you!
