Nope, not seeing this. Windows machine? Try resetting the network settings/running the network repair thing, as sometimes Windows networking just breaks, for no apparent reason.I am fully updated, FW and Driver, but my upload speeds are severely limited. I have a 10Gig link between my desktop and my NAS. Gigabit service from Verizon Fios. My upload speeds peak at .5 to .6 Mbps. My local copies from my machine to my NAS are also severely limited, upload speeds to the NAS are limited to about 100KB/s. If I switch out to the a 1Gig NIC, everything works as expected. Anyone else experiencing any issues?
