I just bought a new wireless setup, consisting of a Cisco E2000 router, Edimax 7718un USB adapter for my laptop and an Edimax 7728in PCI adapter for my HTPC (which isn't in a location I can run cat5 to).

I have to stay in the 2.4GHz band because I have an iPhone and a Wii that will need to connect. I'm aware that 11g devices will drop speeds for 11n devices, but they aren't connected yet.

The fastest connection I've been able to get, with the router within 5 feet of either the laptop or HTPC is 144Mbps. The router has settings for "20MHz" and "Auto (20 MHz or 40Mhz) channel width, which I've set to the "Auto" setting. I haven't been able to find anything similar for either of the Edimax adapters.

This is the first I've dealt with 11n, so I'm not even sure what else could be causing a problem. How do I get up to 300Mbps, or at least a fair bit closer?
