Hello, I have an Asus Router RT-n66u router and updated with latest merlin firmware (65) when I am connected wirelessly to 2.4 MHz I receive very lousy speeds compared to 5 MHz. I can't get over 144Mbps. Pretty much set to Auto on router except for wireless channel set to 11. Also have Comcast and should be receiving 200 Mbps download and barely receive 85 Mbps on 2.4 MHz. What is wrong or what should my Asus Wireless router settings be for 2.4? Thank you
