Maybe your network environment, wifi configuration cannot be automatically upgraded
You can try manually modifying the router's settings
Please cancel automatic in the router's LAN settings, and change it to manual IP (if there is no LAN setting option, but there is HDCP& NAT option, please also change to manual IP/Static IP), and the Subnet mask is changed to 255.255.255.0, refer to the right picture
After the modification is completed, the app configures the hub to connect to wifi, and then see if the hub can be found.
