I'm currently using LENOVO Y5070 with Realtek 8723BE wireless card(VERY VERY BAD). I have heard that there is whitelist on bios . so I want to replace into Intel AC7260 with FRU P/N : 20200552. (base on lenovo part list on pdf)

" WirelessLan_Intel, Intel 7260 2x2AC+BT PCIE M.2 WLAN V2 Part number : 20200552 "

But I can only find the card with FRU P/N : 04W3806  and  LC L/N : 20200552 (with FRU P/N:04X6007) 

My question is

1.which one will work with my laptop ? Can I use different FRU P/N but same model and capable for LENOVO ?

2. Do LC P/N is the same as FRU P/N ?

Thank for any reply

can some one help me plz
