Not Enough Lan Outlets On My New Gateway

Hi

Maybe a silly question but here goes,,,  I just recieved my new Gatway modem as im connecting to the NBN this week ( Fibre to the node )

I have noticed it only has two LAN outlets ( yellow ) i have four devices that are "harwired" in my current adsl router.. i dont want these devices to use wirless as its slower (PS4) and some dont have wirless like my two desktops.

I would have thougt a 4 port router would have been standard not a 2 port one :/

Thanks For your time !
