PPPoE is short for Point-to-Point Protocol over Ethernet. This means you need a specific username and password from your Internet service provider (ISP) before accessing the Internet. This is typical for many DSL connections.
If you’re not sure what your username and password are, contact your ISP and ask for your PPPoE account name and password. You’ll need to enter these when manually configuring your WAN settings.
Once you have your account name and password, here’s how to enter your PPPoE information.
Open the Google Wifi app.
Tap the tab, then Network & general.
In the ‘Network’ section, tap Advanced settings > WAN > PPPoE.
Enter your account name and password. Verify the password, then tap Save.
Reconnect the ethernet cable to your Wifi point.
