@JKeith what are the speeds you are paying for to your ISP? try maybe relocating your nodes... from the screen shot it seems they may be a tad bit too far apart.  also try rebooting your system, that includes all nodes. check if there is a firmware update 

lastly try connecting the back haul via Ethernet cable..

  @jake26 500MBPS is what I am paying for through WOW.  I believe this is an App issue.  When I run the speed test on my PC and my devices connected via wi fi, I get the relatively high speeds.  It just is not represented on the App speeds.  I have no issues with streaming, etc.
