Your ThinkPad has a BIOS whitelist for wireless network cards. Any network card installed in the mini PCI-e slot that is not in this list will cause this 1802 error.

Unfortunately you will have to purchase the proper Intel 5350 card for use on your T400. That would be FRU 42T0965. You may be able to purchase it direct from Lenovo.
