Hi,
Just purchased the DWA-556 for my desktop as I can't run a cable to the router from where the desktop is. The performance is horrible. My Lenovo T510 gets a better connection and faster speeds in the same location. The distance between the router and the computer is ~30 feet or 10 metres.
First, here's the details and settings:
* Win7 64-bit
* DWA-556 driver 9.2.0.105 (Atheros AR5008)
Settings for the adapter:
11d mode switch: disable
802.11 BT high speed: disable
802.11b preamble: long and short
AdHoc 11n: disable
Adhoc Channel: 11
AntennaSwitch: Auto
Auto Transmit Rate: Enable
Backgroundscan: Off
Dynamic MIMO power save: disable
Green Tx: disable
Map registers: 256
MFP: Enable
Network address: Not present
pcieAspm: Off, Off
Power save mode: Off
Receive buffers: 256
Roaming policy: Normal
RSSI threshold: Normal
Scan valid interval: 60
Transmit buffers: 512
Transmit power: 100%
Wireless mode: 11nbg (40Mhz)
Settings on the DIR-655 router w/ Firmware: 1.34EU, under Advanced Wireless:

So basically, how can I improve this? Thanks!

Aw, no one?
Edit: I'm now seeing about 21.5 mb/s or ~2700KB/s. Not really "N" speeds. I've changed the settings to these:

And here you can see the statistics on the DIR-655, about every other time I refresh the page the errors goes up, so something's not right:
