It may be caused by the fact that the wifi configuration cannot be automatically upgraded You can try to modify the settings of the router Please cancel automatic in the router's LAN settings, and change it to manual IP (if only HDCP& NAT options are available, please change to manual IP/Static IP), and change the Subnet mask to 255.255.255.0 After the change is complete, the app configures the hub to connect to wifi, and then see if the hub can be found. If it doesn't work after trying, please contact us for a replacement
