I'm running a 2010 MP and have recently upgraded to a Cisco E3200 802.11n router. Doing an Option-click on the Airport menubar icon shows a Transmit Rate of 54 consistently; sometimes lower briefly. I have a MBA sitting right next to the MP reporting a Transmit Rate of 108 (still slower than expected on an N-network). Doing a wireless transfer between machines maintains a steady 3.4 MBps (~27 Mbps) throughout. I've tried multiple configurations of wireless security, channel frequencies, and bonding. None can get the MP above a rate of 54 Mbps. System Profiler reports 300 Mbps link speed, so it's recognizing that it's on an N network (I know the real speed is much lower, but it should be faster than I'm getting). Any suggestions? Thank you very much. EDIT: sorry, I should have stated that it's a dual-band router and neither 2.4 GHz or 5 GHz improve matters much.
