I need help with WAN Miniport Network Adapter

Hello everyone,
I've got some network issues on my Toshiba Satellite laptop. The Network Adapter does not appear on the Device Manager. This is just the first time that I am going to use my Ethernet port, yet it doesn't work. I can use the wireless connection with no issues but the not the Ethernet. The network adapter I am using is WAN Miniport L2TP. I tried searching on the Internet for some help but there is no such issues that matches my query. If there is someone here who encountered the same issue and managed to resolve it, kindly please help me. Thanks.
