Works great with madwifi drivers under Fedora Core 4. Haven't tried WPA. Apparently some cards with the exact same name may use a different chipset (Europe vs. USA - mine is the USA version).

Works great with the Atheros drivers, Ubuntu was the first OS i saw that included the correct drivers out of the box.

I am using the card for a couple of years now, and it works seamlessly well. I use it with WPA2-PSK with AES encryption, and the card has shown to be very stable even with low signal levels.

Very happy with this card, the box saysHW ver. B4 , lspci reports : DWL-G520 Wireless PCI Adapter(rev.B)
Works as hostap which hostapd, good signal.

I have this card and install the driver and I can make iwlist scan take out keys, but the problem that this card is not connected to the ap in free way and WEP it uses the madwifi.
