HELP! Received a new Hub and have set it up. How do I connect new network and password? Thanks

Alternatively, rename the new SSID and password to be the same as the old Hub.  This will save you having to reconnect your devices to the new SSID and password.

If you mean how do you connect your devices to the hub, there should be a sticker underneath with the wi-fi network name and wi-fi password.
