I am using the Intel Ultimate N WiFi Link 5300 wireless adapter with the E4200. I am only able to connect at a maximum of 300Mbps on the 5GHz band - even when I am only 5 feet away from the router. My understanding is that both this wireless adapter and this router support 450Mbps. Is there something that I need to set to enable this feature/speed?

I have a Lenovo X201T with Intel Ultimate wifi and have seen very brief moments at 450mbps, but I didn't configure anything special. In the end I would not expect a connection at that speed to be consistent and even then...only at very close range.

I have been able to achieve a consistent connection at 450Mbps (at close range) using an Intel 5300 adapter. After much testing, I realized that the Channel does not really matter (i.e. you can leave it set to "Auto"); however, the Channel Width MUST be 40MHz (whether you set it specifically to "40MHz only" or leave it set to "Auto" and hope that it will use 40MHz).

Also make sure that the client card isn't locked to 20MHz (mine was). Go to Client Card >settings >Advanced >802.11n...5.2 band - set to "Automatic". (In addition: If you have Intel PROSet/Wireless WIFI software you can lock your SSID profile to 5GHz under "Advanced settings") After doing this i now have 400 - 450 Mbps in close range.
