So on a clean boot i see over 1gbit on wan down, but after a while it slows down to about 100mbps. LAN never slows down. My other devices on my network do not have this issue either. When my primary device’s wan slows to a crawl the others are fine. I have to reboot every few hours when downloading stuff.
I have disable energy efficiency. Not bad cpu thermal or busted drive. When slow down happens I see nearly fully lan speeds. But wan is at a snails pace. Only on this single device. Task manager does not show any incoming bandwidth beyond what I am attempting to download. I am switching out my nic. I have had issues with aquantia specifically over the years. I have a intel x540. Going to see if that has the same outcome. Taking it out of a defunct server. X550-t2
