[Request] Lenovo IdeaPad Gaming 3 15IMH05

[n_joy2day@yahoo.com]

I’m trying to replace Intel AX201 with Intel AX411 wireless adapter.
Smbiosbios version = EGCN36WW
 
https://download.lenovo.com/consumer/mob...cn38ww.exe
 
I’d like to create backup of current BIOS or System files before proceeding.  Do I need to create a backup image on a thumb drive?
 
I don’t know how to dump current BIOS into a format you desire. Please advise.

Thank you very much for your help.  I apologize for my inexperience with these things; as I'm not code saavy at all.

My Ideapad 15IMH (10300h) was delivered with a Intel 9560 (CNVio) and the wlan is fully functional. An Intel AX211 i can see in the device manger,but only with an exclamation mark. is there a whitelist?
