I have tried a new ethernet cable and it did not help. I also tried rebooting the main Deco and going wired from the main unit. I am getting download speads, less than 10MB sometimes dropping below...

Please note my Deco W2400 is not listed in the model list. I do not know what hardware version it is. I know the firmware is the latest version. I have spectrum 100MB internet I setup mesh network...
