Lenovo T400 - 1802 unauthorized network card is plugged in

[Arek]

Hello Everybody!

I have got a little problem, and if somebody could help me, I would be very-very grateful!
I bought a 4965 a/g/n WiFi card to my T400, and very precisely and correctly I have connected all 3 antennas to the WiFi card.

Everything if fine, but when I start up the notebook, the famous "1802 unauthorized network card is plugged in" just appears. Due to I have found some solutions but NOT to T400, I would like to ask how can I solve the problem to allow my T400 the WiFi card (because this is not an original - when I bought the notebook, there were NO WLAN inside of the machine ...)
Thank you very much, and I am waiting for some solutions (Respect!)
