I honestly think that I've solved all the problems with my DWA-552. Ever since I purchased it I had all kinds of trouble with it, to the point where I was going to box it up and return it. So I was trying all kinds of drivers and messing around with driver settings and I think I found a solution. At first I was never able to hold a connection for more than a few minutes and would get maximum 2 bars. Now I get full bars and get the maximum possible speed, mind you I’m using G.
What I did first was delete and uninstalled previous drivers and Dlink software I was using. I went to http://forums.laptopvideo2go.com/topic/15297-latest-atheros-modded-driver-for-windws-7-vista-and-winxp/ and downloaded the latest atheros drivers. After installation I found no improvement at all and found it was worse. So I played with the driver settings in the advanced section.
So here’s my setting if it can help anyone else out, but to be honest I couldn’t deifier what a lot of the settings mean so I just did some trial and error until I had it working the way I wanted it to.
11d Mode Switch: Enable
802.11 Bluetooth: High Speed Enable
802.11b Preamble: Long and Short
AdHoc 11n: Disable

RSSI Threshold: Normal
Scan Valid Interval: 60
Transmit Buffers: 512

Wireless Mode: 11(2.4GHz) and g and (doesn’t show rest)
So if anyone can understand what all of these modes mean and improves the settings I’m using I would be pretty happy to hear some feedback.
