This is the official Lenovo documentation:
Numeric Error Code 1802 - Unauthorized network card - Lenovo Support (ES)
https://support.lenovo.com/es/es/documents/ht001309
I don't know any fix or workaround to this, other than reflash
the BIOS with Libreboot.
Unfortunately, the list of accepted network cards cannot be
found. So far, all Trisquel-compatible wifi cards are known to be
blacklisted (or rather, not whitelisted) by the X200 BIOS.
