With, for example FTTC, where a modem is provided for you, or with BT FTTP or a CityFibre service you would usually plug in a router and configure the router with your username and password. However, you can use a computer instead of a router, and get online by just plugging the network port of your computer in to the modem and set up a 'PPPoE' connection...

General Settings

PPPoE Service Name = Blank
PPPoE username = as supplied, e.g. x@a.1
PPPoE password = as supplied

Some services - eg CityFibre require a VLAN to be configured on the network card - not all computers will support tagging with a VLAN. eg, on windows, you may be lucky and see a VLAN ID option in the network adapter properties.

Windows 10/11

To set up a PPPoE connection on Windows, follw these steps:

PPPoE Settings in Windows

VLAN ID on Windows

If needed, eg for CityFibre, You will need to set the VLAN in the Ethernet Adapter to 101. If your network card supports it, you can find the setting under:

Start -> Settings (cog icon) -> Network and internet
Change adapter options
Right click on the network adapter (eg named Ethernet), click Properties
Click Configure button
Click Advanced
Scroll down to VLAN ID, if it's listed, and set the Value to 911 (image opposite)
Click OK

Set it back to 0 when you've finished testing.
