Looks like an Atheros AR5212. Same as the one in my Thinkpad.

How are you configuring this? The netmask is bogus. e1ffff00? Very
weird! If it is a static address, try "ifconfig ath0
192.168.1.111/24". You may also need to set the default route with
"route add default 192.168.1.1" (The last digit may need to be changed
if your router is not at .1) If it is DHCP configured, fix your DHCP server!

Nope, turning the bluetooth off and on will have no effect on the
atheros and, unlike on Windows, the ath driver only turns on the LED when
it is transmitting, so, if it's misconfigured so that it does not
transmit, the LED will not light at all.

With that configuration, I would not expect it to do so.
