I can only connect to my router's (Cisco-Linksys E4200v1 running dd-wrt) NG-Mixed radio running on channel (11 - 2.462 GHz. / 20 MHz Channel Width / AES) not the 5Ghz N-only channel (161 - 5.805 GHz. / 40 MHz Channel Width / upper Extension Channel / AES). I can get max 6mbps connection speed. Anyone able to connect at N speeds?
