Não é possível conectar-se à Internet usando uma placa Realtek Lan RTL8105TA

1

Eu fiz um LiveUsb para o Elementary antes de instalá-lo no meu notebook. Tudo funciona bem, exceto pela internet. Eu não tenho WiFi, mas uma conexão com fio. Não consigo me conectar à internet de forma alguma. Minha placa Ethernet é uma RT-8510 da Realtek Lan.
