The Advanced Setup area of your modem's user interface lets you change several settings that give you greater control over your modem's operation. These settings are best for tech-savvy folks who understand a bit more than the typical user about modems and networking.
You can access the Advanced Setup menu by following the steps below:
1. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.
2. Open a web browser and type http://192.168.0.1 into the web address field.
3. Log in to the modem's settings interface (Modem GUI) using your Admin Username and Admin Password. Note that these are different from your wireless network name (SSID) and WiFi password (security key).
You can find the Admin Username and Password printed on the sticker attached to the side, back or bottom of the modem.
CAUTION!Do not remove or lose your modem sticker, which includes your default admin username and password. These preset credentials cannot be retrieved, and your modem could become unusable without them.
DNS Host Mapping: Creates a static hostname for the specified IP address in the DSL router. WAN and LAN IP addresses are supported.
LAN Subnets: Your modem can support multiple LAN subnet settings. Use the DHCP Settings page to configure the default IPv4 subnet.
CBRAS configuration:CBRAS is a specialized CenturyLink remote access server that allows multiple sources of internet traffic (cable, DSL or broadband wireless) to converge in a single network.
QoS: Prioritizes traffic types (such as VoIP) before standard data traffic. Traffic shaping your network with QoS can increase application performance and prevent your network from becoming overloaded.
Remote GUI: Enables access to the router from a WAN connection. To access your modem remotely you will need to use https:// followed by the modem WAN IP address. You can manage the Administrator Username and Password for the modem GUI here.
Remote Console: Enables telnet or SSH access to the router from a WAN connection using the WAN IP address of the modem.
Static Routing: Adds routers manually to the routing table. If a change or a failure occurs between two statically defined nodes, traffic will not be rerouted and must wait for the failure to be resolved by the administrator.
Administrator Password: Prevents outsiders from accessing the firmware settings of the modem. After creating a username and password, you will need to enter them every time you access the modem firmware GUI located at http://192.168.0.1.
Port Forwarding: Allows you to enter ports or port ranges to forward Internet applications to a LAN device.
DMZ Hosting: Enables a LAN device to use the modem WAN IP address as its own. DMZ places the LAN device outside the firewall.
IPv4 Firewall: Activating the firewall is optional. When the firewall is activated, security is enhanced, but some network functionality will be lost.
IPv6 Firewall: Activating the firewall is optional. When the firewall is activated, security is enhanced, but some network functionality will be lost.
NAT (Network address translation): Turning off NAT will open your Broadband Modem to outside intrusion, creating a security risk. These settings should not be changed unless instructed by your ISP.
UPnP: Simplifies the connection and implementation of devices to your network.
SIP ALG: Enables or disables the ability to pass SIP sessions to the LAN.
NOTE: Depending on your modem, your settings interface may appear slightly different from the images below.
On modems that have Secure WiFi, some advanced features in the modem settings will be disabled, including:
Instead, you can easily access these same network controls through My CenturyLink or the app. Secure WiFi is available on leased modems with model numbers 1100, 3000 and 4000. Review our FAQs to learn more.
