I am looking to get a 600Mbps connection from my Wifi Extender if possible. I am currently getting 100Mbps. When on a Wifi connection I get 150Mbps. I have the TP-Link PA4010 kit. My Wifi card is the ASUS PCE-N10 11n Wireless LAN PCI-E Card. My ethernet is Realtek PCIe GbE Family Controller. My router is the Virgin Media Hub 3.0. I am using Cat6 cables.
