my Thinkpad X61s and new WM3945ABG dosen't work ERROR1802

[anostapchenko]

Good day!

Some days ago I have bought INTEL WiFi WM3945ABG MOW1 on Ebay.com from Honk Kong. But when I inserted this board in my X61s and restart it I have seen next message – ERROR1802 unauthorized mini-PCI wifi card pleas switch off your PC and remove it.
In this form I found a lot of discussion about the same problem with ERROR1802 and PCI wifi cards but unfortunately I still don’t understand how to solve my problem.

Dose it possible to use this INTEL WiFi WM3945ABG MOW1 with my X61s or not?
What do I have to do?

Some authors suggest upgrade BIOS version of X61s other ones rewrite internal sub-system ID of INTEL WiFi WM3945ABG MOW1. Also I found information about pin 20 isolation of INTEL WiFi WM3945ABG MOW1.

Which way is right for me?

Unless you want to run a modified (hacked) BIOS on your X61s (plus tape pin 20 and the hardware wireless on/off switch may not work), you need the IBM/Lenovo version of the Intel 3945ABG. Other vendors or generic versions of the of this card won't work with the standard BIOS. I've got a few of these lying about as I've upgraded my ThinkPads to N-wireless cards (mosltly Atheros based). If you have PayPal, I'm happy to send you one for minimal cost plus postage. Send me a PM and we can work it out.

Cheers,

@Morkli! Maybe you know information about link to modified (hacked) BIOS. Zender BIOS will fit for my problem?

Sorry, don't know of any link. I believe you need to send Zender a PM with your ThinkPad details and he will reply to you in time. Taping pin 20 plus a Zender BIOS should make your WiFi card work.
