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

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.

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.
