Description (Last modified by mrenzmann)

Hi,

I have an atheros based card in my x86-64 box configured as AP for the dell d610 laptop with winxp32 onboard. Here's more details...

hardware:

01:06.0 Ethernet controller: Atheros Communications, Inc. AR2413 802.11bg NIC
        (rev 01)
        Subsystem: Atheros Communications, Inc. TP-Link TL-WN510G Wireless
        CardBus Adapter
        Flags: bus master, medium devsel, latency 168, IRQ 18
        Memory at fdef0000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [44] Power Management version 2

tested software:
