Ubuntu Networking :: Hardware Switch Doesn't Work For Atheros WiFi

i'm running Ubuntu 10.10 32-bit on an Acer Aspire 3050 laptop with an Atheros AR5BMB5 WiFi card.

The problem i'm having is that the hardware switch to turn the WiFi on and off isn't working right. When I hit the switch to turn it off, the light doesn't turn off, and Ubuntu just disconnects from the network and searches for more WiFi networks - it doesn't say that the WiFi has been deactivated, and I don't think it is. When I hit the switch again, it finds my network and connects to it.

The lspci -v | less command gives me the following information for the WiFi:

Code:
08:04.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)
Subsystem: AMBIT Microsystem Corp. Device 0418
Flags: bus master, medium devsel, latency 168, IRQ 21

[Code]....

It lists a different model of card, but it's using what I assume is the correct driver, so I don't know if that has anything to do with it. I've checked the card itself and it is a AR5BMB5.

I would like to fix it so the switch actually turns the WiFi off instead of just making it search for more networks (I assume it's not actually turning off), and perhaps make the light turn off as it should as well.
