Guys, I really need your help, they helped me install OpenWRT ( BIG thanks for helping @LokeYourC3PH ) on the Netgear R8000P AC4000 router, but Wi-Fi does not appear, PCI does not find the device (The firmware does not support the latest revision of the router or did I forget to install something from the repository?
There are a few threads about this, the wireless hardware is not supported due to Broadcom being jerks

Are you saying that I disassembled the router (serial port to TTL) and everything is down the drain?)) I like OpenWrt, is there really no way to make Wi-Fi work?
CRY!!!!!!!!! 
I'm sick of the mere sight of the original firmware
It will work as a quick wired router, but Broadcom wireless is rarely supported and when it is the support is limited and sparse.
This is a decision made by Broadcom, nothing the openwrt devs can do about it.
If you’re ok with running old kernels with black box binary blobs ddwrt, tomato etc may have supporting images but these firmware options aren’t supported here.
What method did you use to install openwrt?
