need help to make DWL-G650+A working

[Apphome]

my laptop isT42 2373 8zu working under 10.4.5 T42 2373 KH6/KB6 P M 725 1.6G(2M cache), 1.25GB RAM, 60GB 5400rpm HDD, 14.1SXGA+(1400x1050) TFT LCD, 64MB ATI Radeon 9600, 24x24x24x/8x CDRW/DVD, Intel 802.11b/g wireless(MPCI), Modem(CDC), 1Gb Ethernet(LOM), UltraNav, Secure Chip, 6 cell Li-Ion battery, Everything is working under 10.4.5 except wireless support.

 

I bought a DWL-G650+A and install 10.4.5 with patch. the card can be recognized as Atheros Communications.inc, AR5001-000-0000, h/w ver:D1, f/w ver:4.10.

 

My problem is :

 

when I plug in the card, the "act" light blinks, but the "link" light doesn't work. I'm a fresher of mac osx86,

is there any nice guy can help me to figure out how to make the DWL-G650+A works ?

 

thanks so much.
