Lenovo G455 notebook, atheros AR9285 wifi problem

[Mikhail TSaplin]

Hello All!

I have Lenovo G455 notebook with FreeBSD 8.1 installed on it.

Notebook has an Atheros AR9285 WiFi card that normally attaches to the ath driver. But i cant to enable it.

I do the following steps:
1) Turn on WiFi switch on the notebook front panel;
2) Powerup notebook - WiFi led is on;
3) System loads BIOS, bootmanager, FreeBSD system boot loader - WiFi led is on;
4) System starts kernel booting - and WiFi led turns off within kernel loading process (probably when acpi driver is loading);
5) Dmesg and ifconfig - shows successfully attached ath device;
6) I enter following commands:
ifconfig wlan0 create wlandev ath0 - wlan0 device is created;
ifconfig wlan0 up scan - and this command hangs - probably that the WiFi is disabled;
7) I tried to enable/disable WiFi front panel switch, push Fn+F5 (wifi enable conbination) - the WiFi led is still off;

Can you help me to enable it?

Thanks for any advice.

Mikhail.
