Client Adapter? I ready that i need gygabit port for lan cable to my pc and ps4 to get internet connected on maximum high speed! Isnt it ?
Ah, you are talking about wired connectivity - i had assumed wireless.
That router only has 10/100 Mbps Ethernet ports; indeed you will need one with gigabit ports.
Lots of choices with TP-Link, just go here:
