Iy sounds like you are saying that your Mac is able to connect with a Wi-Fi network but the network device is not connected to the internet. Would try directly connecting via a wired Ethernet connection to see if internet access is available there. Try restarting the modem to reset it. Otherwise, be sure that the modem is securely connected to the internet. If so, then contact your internet provider for assistance.
