I finally found the problem!  Killer Performance Suite - even thought I have never used it or set it up. I deleted  the killer  performance app and only installed latest drivers.
Hi All, Have you noticed and/or experience slow speeds with the new drivers for the E2600 Killer Network Card (integrated network card) on the Aurora Ryzen Edition R10? I rolled back to the 10/1/2021 10.53.1001.2021 and my speeds are back. Roll forward to couple of new ones and my speed decreases. This degraded performance is only with drivers after the 10/1/2021 10.53.1001.2021. Newer Drivers: I installed the Open Speed Test Server and did multiple runs. With the latest and greatest I see a degradation of almost 20%. ~ 780 Mbps bouncing up an down I have a NAS and uploading files from the Aurora to the NAS I see a degradation of almost 40 % ~600Mbps bouncing up and down 10/1/20/21  10.53.1001.2021 Driver.  I see ~980Mbps steady. I would like to run the newer driver, any advice?
