Forgive my poor English, please.

 

My laptop model: Samsung R428, CPU: T4400 2.2MHz, Wireless: Atheros AR9285

 

I installed Lion 10.7.5 with chameleon boot. To drive my AR9285, I modified the S/L/E/IO80211Family.kext, find AirportAtheros21.kext&AirportAtheros40.kext, patched the device id from 168c,2a to 168c,2b. Everything seems OK.

 

But the problem I found then: When I switched the power of my laptop, from AC to battery or from battery to AC, the wireless connection broke in a few seconds while the WLAN icon changed into grey. The connection can't be restored unless reboot the system.

 

I guess the problem caused by power management, so I patched the DSDT file to make AppleInterCPUPowermanagement work. The problem remains.

 

Any comments? Thanks again.
