Resolving PPPoE error messages when setting up router
Point to Point Protocol over Ethernet (PPPoE) is a type of broadband connection that provides authentication (username and password) in addition to data transport. Most DSL providers use PPPoE to establish Internet connections for customers.
This article will enumerate the possible error messages when setting up your Linksys router with PPPoE configuration and how to resolve these errors.
There are four error messages that you may encounter when setting up PPPoE on your router:
PPPoE Authentication Failed
You are getting this error message because you have entered the wrong username and/or password for your PPPoE account. To resolve this, you can either check your username and password provided by your Internet Service Provider (ISP) during the installation of your Internet or you may contact your DSL service provider to verify. Once you have verified your PPPoE account, you may now enter them on the router’s web-based setup page.
NOTE: Some ISPs require the extension @isp.net, where isp is your Internet Service Provider.
PPPoE LCP Negotiation Failed
You are getting this error message because there is a problem with the account you entered on the router’s web-based setup page. To resolve this, check if your account is active and verify your username and password with your Internet Service Provider.
Cannot connect to PPPoE Server
This error message appears when your ISP’s server did not respond to your request. To verify if your ISP’s PPPoE server is online, connect your computer directly to the modem and see if you can connect to the Internet. If you’re online, connect your computer and modem to the router and perform a powercycle.
Can’t get an IP from PPPoE Server
This error message means your request was received by your ISP’s server but did not assign your router a public IP address. To resolve this, perform a powercycle.
Powercycle is one way of restarting your network. This process will include having the modem re-establish connectivity with your ISP’s server.
Shut down your computer.
Unplug the router’s power cable.
Unplug the Broadband modem’s power cable for 30 seconds.
Plug in the Broadband modem’s power cable and wait for the lights to become stable.
Plug in the router's power cable once the modem’s lights appear stable.
Power ON the computer and test the Internet connection.
NOTE: If the router is still receiving the PPPoE Error messages, verify if the Internet connection in the Broadband modem is active by connecting it to the computer using an Ethernet cable without the router installed. If you cannot access the Internet, contact your Internet Service Provider.
