@ACMiller Here's what you need to do... with every special option disabled... Make it a vanilla wireless. Click on the client list and click on the THREE dotts on the right. Enable Customized...

@Eisen Which APs did you install for this client? How many wireless devices does he have running?

@Eisen Can you give us more details on your clients setup? Whats the WAN speeds? Thanks, KG!

@djsdjs Also update the firmware to the latest version...

@djsdjs Yup its in the Router Admin GUI and or in the Omada Controller (if you using it). I think its in the WAN/LAN setting side of the router admin gui.

@djsdjs Do you have hardware acceleration enabled on the 605? If not, enable it, and retest.
