I have a Lenovo Thinkpad T410 laptop (Product number: 2522AA9, BIOS: 6IET85WW (1.45) ). A glass of water was poured on the laptop and it fellt down from desk. Motherboard was damaged I bought a motherboard installed and it worked. I realized that WiFi card was also damaged as it fellt down. I bought exact the same model (If I recall correctly it is Intel WiFi card) but I am getting 1802 Error: Unauthorized network card at boot.
I searched for this problem a lot and found some pages that explain how to fix it. No method worked for me. One of the solutions is that, there is a no1802.iso file it must be burnt onto a CD but I don't have any CD/DVD Burner. So I created a bootable USB stick with this iso file and booted laptop from USB stick but it didn't help. The problem is still there.
How can I solve this problem?

The "no1802" utility was only for much older machines. It won't work for you.
The same model isn't enough. You need one with a Lenovo FRU on it. The same card can have different firmware on it. When Lenovo or another manufacturer gets a machine approved for sale, they need FCC certification regarding emission levels in U.S. and other similar things in other countries. The FCC certification is for a particular model computer and the wireless card(s) that were tested with it including the firmware tested. You probably bought a card that was certified for use in a didderent manufacturer's computer.
