I installed a DWA-552 on a recently rebuilt Windows Vista Home Premium machine (specs below). I immediately started having system lock-up issues. Based on what I'm reading on the web, I figured this was a driver issue. I decided to start playing with different installation options, doing a complete uninstall after each one. I tried moving the card to a different PCI slots, installing with the D-Link installer, and installing by just updating the driver in Device Manager. In each case, the lock-up problem persisted.
After looking around the web, I found and installed the Atheros 7.3.1.73 driver. (The D-Link driver V1.30 includes the Atheros 7.3.1.42 driver.) This one seems a lot better, I have had only one lock-up (while running a full anti-virus scan) in the last eight hours. I have some lingering weirdness with acquiring an IP address after reboot and/or dropping the wireless connection requiring a reboot before being able to reconnect. However, I can't seem to get a handle on the specific steps to recreate either problem at this point.
This lock-up problem seems definitely related to the Atheros driver.
I hope Atheros and D-Link resolve this driver issue ASAP and get a supported driver out to us all. Since loading the 7.3.1.73 driver, I am getting really good throughput (Vista reports an up-to-300Mbps link) and the connection with my DIR-655 has been mostly stable.
