Hello and thanks for reading!
PC
NIC 1 (onboard) = 2.5 GB (directlink unraid)
NIC 2 USB = 1 GB (tried 2, one realteck, one linksys) - internet
NAS (unraid)
NIC 1 (onboard) = 1gb - internet
NIC 2 = 2.5 gb- direct link PC
LAN internet is /24 192.168.1.x (multiple devices, some static, some not)
direct link is /24 10.0.0.x
The issue stands like this. If on the PC, windows 11, i disable the "internet" nic, the USB one, the transfer is as expected 220-240 mb, but if the USB internet NIC is on, it caps between 20-40 mb.
I`m 100% the "internet" NIC is at fault, because i was transfering to the Unraid to 30-40 mb, and once i disabled the USB NIC it skyrocketed to 230-240 mb
Does anyone on this planet know how and why activating the secondary NIC throotles down the direct link NIC ?
