I have an ASRock Z97 Extreme6 mobo with an Intel Ethernet I218-V LAN port and Realtek RTL8167 LAN port. I'm using Win10 and dual-booting between Windows and Ubuntu. I'm supposed to have 1000Mbps service to my home. I can get nearly that much (about 900Mbps, according to my provider's speedtest website) when I boot to Ubuntu. However, when I boot to Win10, the best I can get is about 25Mbps on either port. I've updated all LAN drivers that I can find, and I believe I have the latest bios (not updated since ~2015, however). I'm currently using a USB wifi connection that's getting about 40Mbps for Win10. Can anyone provide any clue as to why I can't get the full speed? TIA.
Sorry to cross-post this, but I haven't found a solution in networking. Here is my original question in the networking section. The tl;dr of it is that my desktop is an ASRock Z97 Extreme6 dual-booting between Win10 and Ubuntu. I have 1000Mbps service run to my home. Every other PC in my home gets full bandwidth from the LAN (~920Mbps). When I'm running Ubuntu on this desktop, I also get full bandwidth from the LAN. When running Win10, the best I can get is ~90Mbps. I've updated all bios and LAN port drivers (the mobo is no longer supported). I've followed all advice in the other thread. I've also contacted ASRock Tech Support. They say the LAN ports are working and suggest a reinstall of Windows. I agree that it seems to be a software rather than hardware problem, but am loathe to do a Win reinstall, especially on a dual-boot drive. Anyone have any other ideas?
