I just bought a Buffalo WZR-HP-G300NH-AP, firmware v1.74. I have one laptop with Intel wifi 5100, two laptops with Atheros wifi. All of the three laptops are stuck at 54mbps and I dunno how to enable to reach 300mpbs. Below are my wifi settings:
wireless radio-ENABLE
wireless channel-6(manual)
300mbps mode: bandwidth-20Mhz
separate feature-DISABLE
wireless authentication-WPA2-PSK
wireless encryption-TKIP
mode of acquiring IP address-acquire an IP Address Automatically from a DHCP Server
My ISP is i-Cable from Hong Kong. I'm using a cable modem. I'm frustrated about the connection speed since my old router can reach 150mbps without any fuss
