On the 'Wired' page, under 'ISP authentication (PPPoE / PPTP / L2TP)', enter 'PPPoE' in the 'Type (Protocol)' field.
Then, in the 'Username' and 'Password' fields, enter the login and password for the Internet connection provided by your ISP.
Click on 'Show additional PPPoE settings' to display fields with advanced settings.
The 'Service name' and 'Access concentrator' fields are optional, leave them blank if your provider has not given you additional information.
Leave the 'IP configuration' field set to 'Automatically' if your ISP assigns an IP address for Internet access automatically.
If your ISP has provided you with a fixed (static) IP address, select 'Manual' in the 'IP configuration' field and specify the IP address and gateway address in the fields 'IP Address' and 'Remote IP' that appear. For example:
If your ISP neither issues nor requires an IP address to be assigned to your router's WAN interface, i.e. if it's network does not have automatic IP address assignment, disable automatic IP address acquisition via DHCP on the WAN port. To do this, in the 'IP and DNS settings' section of the 'IP configuration' field, specify 'No IP address'.
