C3000 N100 and Intel 4965AGN compatibility

2008-05-13, 10:54 AM


I have a Lenovo C3000 N100 notebook (0768-BQG) which comes with an Intel wireless 3945ABG mini-PCI express adapter. I would like to replace that card with Intel 4965AGN (the same form factor) to use the 802.11n standard at home. I am aware that wireless adapters are authorized by some manufacturers and to avoid error 1802 “Unauthorized network card is plugged in. Power off and remove the mini-PCI network card.” I would purchase a card with the Lenovo FRU number 42T0865 (Intel 4965AGN MM1) which is used in some ThinkPads.

Here are my two questions:
1. Is any BIOS version for 0768-BQG machines compatible with the Intel 4965AGN adapter?
(TV Access Connections from version 4.40 seems to be).

2. Has someone already made successfully such upgrading?

I would like to avoid no-1802.com-like solutions.

Thanks for any help, Peter

I am having the same problem with Lenovo 3000 V100. I tried applying a patch on the BIOS provided on ThinkWiki. Howeve, it didn't work. Any help would be appreciated.


I understand that Lenovo maintains a Whitelist on the BIOS, which checks the devices at startup. And there are patches to bypass this option. However I haven't found one for 3000 series V100. 


Thank you.

I would also like to upgrade the wireless card in my laptop, which is a 3000 C200.  Currently has the Intel 3945ABG which barely works - always dropping connection even when sitting right next to the router.


Does anybody know which cards are whitelisted in the BIOS?


I suppose getting any help from Lenovo on this front would be out of the question?

Get hold of the manual for your model and they should all be listed there...
For instance, manual for N200 lists FRU no. 42T0865, 42T0867 and 42T0871 for
Intel Wireless 4965AGN
