    Intel NUC NUC8I7HVK AC 8265 Wifi Slow


      I'm getting pretty poor wifi on my new NUC with AC 8265 Wifi.   I've got 150Mb internet, and am getting around 25mb down consistently.  If I tweak some settings on the advanced settings of the NIC, I can get a little more than that, but not much.   With my macbook pro in the same location, I am getting close to 150mb down, which is what I typically get from all my devices, wired or wireless.


      I've tried 2 different routers to see if it follows, the NUC has slow speed regardless compared to all my other devices.  


      I've updated bios, updated latest drivers, tried enabling/disabling Intel Connection settings for the SSID, nothing really changes.  The best luck I have had, was to totally delete the driver from Intel thru device manager, reboot, and let Windows pick the best one, I was able to get closer to 50mb down.  Updating to latest intel drivers,, speeds go back to 25mb.  Copying files from my NAS on my LAN is also about the same speed, while other devices all much faster.


      Attached is the SSU output of my system.  Running Win 10 enterprise, latest 1803 release.


      Thanks for any advice.
