Works perfect. From screen resolution to usb devices. Installed directly to drive from LiveCD.
The AR5007EG card had no issues whatsoever using aircrack utils. Also, no issues connecting to the internet as some have posted in other threads.
Remember, the 4720Z is a Wal-Mart branded model, so it's possible that it's the same exact setup as other Aspires, just a different model number.
Best of luck in your installs.
