I have been having trouble with the broadband speed, (lack of), dropped connection, (regular), and Netflix seizing. Thought I'd try the recommended 'Connect App' but this does not find my Hub3!
Yes. Forget the Connect app.
Uninstall the Connect ap. and reboot your phone.
What speeds do you get at >> speedtest.net << with a direct connection using a Cat 5E or better cable between the Hub in Router Mode and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?
