Use the Wi-Fi name and password on the card supplied with the service, or on the label under the router. A printer or till that can use a network cable should use a LAN port on the router instead of Wi-Fi.
If the device says the password is wrong, check for a space at the end and that Caps Lock is off. If it still fails, forget the network and try once more. If the password on the card does not work, email the network operations centre. Do not reset the router.
