The default IP address for accessing most of the Actiontec Modem and Routers is "192.168.0.1". The exceptions are the Actiontec Modems and Routers made and branded for a specific Internet Service Provider (ISP). The Modems and Routers made for a specific ISP will have a sticker on the bottom of the device with the default IP address on it. However, the IP address can be changed by the user, so it is important to document and save the IP address when it is changed. It is suggested that the IP address should be written on a label that is then attached to the Modem or Router. If this new IP address is communicated to technical support early in any relevant conversation, it will save time and confusion.
