Hi there

Please try this


The new OS update imposes strict local network protections that accidentally throttle certain third-party controllers. 


  1. Go to System Settings > Network > Ethernet.
  2. Click Details... next to your active 2.5Gb adapter.
  3. Turn off the toggle for Limit IP address tracking.
  4. Click OK to apply.
