I would be very grateful for some help with improving my download speeds on my Windows 10 laptop. I have a 1 Gbps FTTH broadband connection, which has an average download speed of 900 Mbps. If I use a bootable Ubuntu USB stick on my laptop, I can consistently get download speeds of 800+ Mbps on a wired connection to my router, but when I am using Windows 10, the fastest download speed that I have achieved is 280 Mbps. I have run the TCP/IP Optimizer and chosen the optimal settings, tried both normal and experimental for TCP Window Auto-Tuning, and also tried disabling all offload settings on the NIC. Is there anything else that I can try? The NIC in my laptop is a Qualcomm Atheros AR8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30), and I am using driver version 2.1.0.27 dated 18/09/2017, which I believe is the latest driver version available.

Thanks,

Tim
