first of all, this is my router:http://www.tp-link.in/products/details/cat-9_Archer-C20.html , it says that on the website that the 5GHz band has 433 mbps wireless speeds, so I tried wireless LAN file sharing but I get a max speed of 100mbps or somewhere around 9MB/S, am I not supposed to be getting at least 30MB/S? thanks in advance!
