Cuando tu contratas una conexion a internet con un ISP (Proveedor de Internet) tienes 2 redes. Una la que realiza tu proveedor contigo a traves del "modem" que ellos te instalan y otra la que se realiza entre el "modem" y tu equipo.
La primera red esta definida segun sea la tecnologia de conexion que usen ADSL, cable, radio, satélite..... y yo añado RDSI, modem analogico (RTB),etc...
Y la segunda red según la tecnología de red que se use (Ethernet, Wifi).
Se pueden hacer combinaciones entre ellas, es decir, una tecnologia de conexion de internet se puede combinar con cualquier protocolo de red. P.e. una conexion RDSI puede establecerse en un ordenador que luego la reparta por Wifi.
Bien, ahora tu duda. En realidad esas 2 redes separadas forma una unica red, y como en toda red la velocidad maxima que se va a alcanzar la va a determinar la maxima velocidad de el mas lento de sus componentes. Pues en este caso SIEMPRE, SIEMPRE va a ser mas lento tu proveedor de internet que la tecnología de red que uses. O sea, que por usar Wifi o Ethernet no limitas tu velocidad de internet.

en.wikipedia.org/wiki/ADSL_modem
A digital subscriber line (DSL) modem is a device used to connect a computer or router to a telephone line which has the digital subscriber line service configured, to allow the computer to connect to the Internet. Put simply, a DSL modem or DSL router is what you need in order to connect to DSL broadband.
The term DSL modem is technically used to describe a modem which connects to a single computer, through a USB port or is installed in a computer PCI slot. The more common DSL router which combines the function of a DSL modem and a home router, is a standalone device which can be connected to multiple computers though multiple Ethernet ports or an integral wireless access point. Also called a residential gateway, a DSL router usually manages the connection and sharing of the DSL service in a home or small office network.
