1802 error on T60P

[vag]

My T60P got the Intel 3945 wireless adapter and I always wanna replace it with a Atheros card. Since there's no ThinkPad 11a/b/g Wireless LAN Mini-PCI Express card (AR5006EX, AR5423) in stock of Lenovo, China, I'v purchased a non-Lenovo AR5006EXS (AR5424) for $22. So after I replaced adapter, the 1802 error bumped out.

the bios version is 1.09, and it seems all no_1802 utility i can find have no use on T60P. I wonder is there any way to make the new adapter work?
