How to Change the WAN Connection Type on Your Router

What the WAN Connection Type Means

Your router has two main jobs: it builds your local network and it connects that network to the internet. The connection to your internet service is the WAN, or wide area network. The WAN connection type controls how your router receives its public IP address and how it talks to your provider's equipment. This setting lives in the router's internet, WAN, or connection type page. It is different from the Wi-Fi settings that control your network name and password.

Most consumer routers label this option with terms like connection type, internet connection type, or WAN type. The common choices are DHCP, PPPoE, and static IP. Choose the one your internet provider supports. Selecting the wrong mode can leave your router with no public IP address, or with an address that does not work for internet traffic. Before changing anything, find the exact requirement from your provider.

Check What Your ISP Requires

Your internet service provider is the only source that can tell you which WAN type to use. The information is usually in your welcome email, on the provider's support page, or on a label attached to the modem or terminal. You may also see it when you log in to the provider's account portal. Look for terms such as dynamic IP, automatic IP, DHCP, PPPoE, or static IP.

If you are moving a router from one home to another, do not assume the same WAN type will work. Providers use different connection methods depending on the technology and the plan. A fiber service often uses PPPoE or DHCP over a physical terminal. A cable service usually hands out an IP address by DHCP. A business line may include a static block. Confirm the method for the current location before you reconfigure the router.

• DHCP: the provider assigns your public IP automatically.
• PPPoE: the provider expects a username and password, usually over a point-to-point connection.
• Static IP: the provider gives you fixed IP settings that do not change.

DHCP: Automatic Address Assignment

DHCP stands for Dynamic Host Configuration Protocol. In the WAN context, it means your router asks the provider's network for an IP address and receives one automatically. This is the most common setting for home cable and many fiber connections. The router also receives the subnet mask, gateway address, and DNS server settings from the provider as part of the same exchange.

To choose DHCP, open the WAN settings page and select DHCP or automatic IP. Save the setting and let the router renew its lease. On most routers this happens within a minute. If the status page shows a public IP address after a refresh, the WAN connection is working. If it shows zeros or a local address, the provider may require a different mode. See DHCP explained for more about how the protocol works.

PPPoE: Username and Password Login

PPPoE means Point-to-Point Protocol over Ethernet. Some providers, especially fiber and older DSL services, require your router to log in before it can get a public IP. Your provider gives you a PPPoE username and password, not the Wi-Fi password. The router keeps that session active and uses it as the first step before requesting an address.

In the WAN settings, choose PPPoE, then enter the username and password exactly as the provider wrote them. The password is case-sensitive. Some ISPs also ask for a service name, but many leave it blank. If your provider uses VLAN tagging for the internet connection, you may also need to set a VLAN ID on the WAN port. A wrong ID can prevent PPPoE from connecting. See VLAN tagging explained and PPPoE explained for the details.

Static IP: Entering the Address Manually

A static IP plan means the provider reserves the same public IP address for you. Instead of requesting an address automatically, the router uses the fixed address and other values you enter. The provider should supply the IP address, subnet mask, default gateway, and DNS servers. Without all four values, the router may connect to its local interface but fail to reach the internet.

Select static IP in the WAN settings and enter each value into the matching field. Double-check the subnet mask and default gateway, because a typo in either one can break routing. The gateway is usually the address of the provider's equipment on your connection, not the address of your router. If the router supports it, you can also enter the DNS servers supplied by the provider or use a public DNS service.

Steps to Change the WAN Setting

The exact menu names differ by router, but the workflow is similar across most brands. Use a wired connection from your computer to the router when you make this change so a Wi-Fi dropout does not interrupt the process.

• Log in to the router's admin page using its local IP address and admin credentials.
• Find the internet, WAN, or connection type section. On mesh systems, look in the app or web portal under internet setup.
• Write down the current settings so you can restore them if needed.
• Select the WAN type your ISP requires: DHCP, PPPoE, or static IP.
• Enter any extra values, such as PPPoE credentials or static IP details.
• Save or apply the setting, then check the WAN status page for a public IP.

Troubleshooting After a Change

If the router cannot reach the internet after a change, return to the WAN settings page and check the status. A WAN IP of 0.0.0.0 often means the router has not received an address. If you selected PPPoE, confirm the username and password, then reconnect the session. If you selected static IP, verify every number against the sheet from your provider.

Another common issue is a physical mismatch. The WAN cable must go to the WAN port on your router, not to a LAN port. Use the correct Ethernet port on the modem or ONT as well. If your router has a multi-gig WAN port, plug the provider link into that port when the plan calls for it. See WAN port types and how to connect a router to an ONT for guidance.

Security and Good Hygiene

Changing WAN settings is a small change, but it touches the boundary between your home network and the internet. Keep the router's admin password strong and change it from the default. Use the latest supported wireless security, such as WPA3, if your devices support it. The Wi-Fi Alliance describes WPA3 as a security protocol that protects against password guessing and requires protected management frames. For general guidance, NIST's cybersecurity work emphasizes protecting connected systems and managing risks.

Open or enable remote management only when you have a specific need, and disable it when the task is done. If your provider uses PPPoE, the credentials are sensitive because they allow the connection to the internet. Store them in a safe place.

What to pick for your use

Questions

What does WAN connection type mean?

It is the setting that controls how your router obtains a public IP address from your internet provider. The main choices are DHCP, which assigns an address automatically, PPPoE, which requires a username and password, and static IP, which uses fixed values you enter manually.

Should I use DHCP or PPPoE?

Use the mode your internet provider requires. DHCP is common for cable and many fiber connections. PPPoE is common for some fiber and older DSL services. Check your provider's setup instructions before choosing either one.

Where do I find the WAN connection type setting?

Look for a section called Internet, WAN, or Connection Type in the router's admin page. On mesh systems, the same setting is usually under Internet Setup in the app or web portal. The exact wording depends on the router brand.

Why does my router show 0.0.0.0 after changing settings?

A WAN IP of 0.0.0.0 usually means the router has not received an address from the provider. Confirm the WAN cable is connected, the router is in the correct mode, and any required PPPoE credentials or static IP values are entered correctly.

Can I change the WAN connection type from a phone app?

Many mesh routers and newer routers let you change the internet connection type from the companion app. If the option is not visible in the app, log in to the router's web interface using a browser to access the full WAN settings.

Do I need a static IP for gaming?

No. Most home gaming connections work fine with DHCP. A static public IP can help if you need to host a server or want more predictable remote access, but it is not required for normal online gaming. Your local devices can still use DHCP reservations for a fixed private address.
