Not plug and play. It has to be activated by your ISP. Connect it and then call your ISP by phone. Have the MAC address ready to give the ISP rep. This is true of all brands. The MAC address of the router is its ID and each modem has a different MAC.
Sorry, there was a problem. Please try again later.Yes, your cable provider must have the new MAC address on your new modem.
