When I test on speedtest.net, I get 100Mbps download speed and see the network saturation skyrocket in Task Manager. When I download Steam and Battle.net (at the same time or separately) I don't see more than 16mbps. If I stop one, the other increases. If I run both, they split that speed. If I run Speedtest.net while downloading, I get maybe 1mbps download and see a minor bump in task manager.
In Task Manager, I see 16 Mbps consistently. Not quite a flat line, but close, it never goes above or below that range by more than 1mbps.
I am using a brand new Netgear R9000 router. Other computers earlier in the day were getting super fast Steam download speeds. I reinstalled windows, and am seeing the same speeds. I have updated the drivers from Asus' website. Downloaded the Intel Ethernet drivers. Not using wireless.
I have checked and there are no limits on downloads in the steam download settings.
I am using a static dhcp lease on this computer. I am running Windows 10.
Any ideas? Sure seems capped, but can't figure out how or where.
