T61: WIFi card atheros ar5423a under Ubuntu

[slungu]

Hello everybody,

I'm having a problem with my new WiFi card in my T61. I have flashed the Middleton BIOS in order to install my new Atheros AR5423a WiFi card. Prior to that, I had tried to run the normal BIOS and it reported some unauthorised card. Changed back, flashed and changed the WiFi card again. Now, the original card was running just fine, but I wanted to get OS-X to work too, that's the reason for the change. Unfortunately, now I have no working WiFi card anymore, since the new one seems not to work or I have done something wrong. The strange part is the card does not appear in the lspci listing at all, nor do I see the LED active. Any idea how I could find out more about the card state ?

The card hat two antenna connectors and the T61 has 3, so I took grey and black and skipped the white one.

Regards, Stefan
