I have an issue when connecting to a particular WiFi hub, after a while it disconnects and won't let me reconnect unless I remove my usb hub adaptor.
However if I connect it to a different WiFi network (I have 2 currently available) I don't have the same issue...
I've looked at all my router settings and there doesn't seem to be a problem there...
Thanks for reaching out. To confirm, have you hardwired your Chromecast to the USB Hub connector? Try to reboot your Wi-Fi hub and Chromecast device. Also, if the issue is isolated with your Wi-Fi hub, please contact your Wi-Fi manufacturer or Internet service provider for additional help.
