I had problems to get my WiFi working on (Lenovo E595 & Asus rog strix z370-e gaming)

error : no "Kernel driver in use" line in lspci output for RTL8822BE
kernel : 5.5 (module less)
driver : built in kernel CONFIG_RTW88_8822BE=y
firmware : rtlwifi/rtl8822befw.bin [https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git]


I tried to include firmware rtl8822befw.bin (also tried rename) but it didn't solve the problem
I found rtw_pci in /sys/bus/pci/drivers/ strangely it isn't used by the device
tried to unbind/bind (echo '0000:01:00.0' > /sys/bus/pci/drivers/rtw_pci/unbind) -> No such device

I was using the incorrect firmware rtlwifi/rtl8822befw.bin (quite confusing non ?)

SOLUTION : use rtw88/rtw8822b_fw.bin

1. I'am using 5.5 version not 5.2 so i hope they fixed that bug (anyway renaming to rtw8822b_fw.bin didn't help)
2. here they say that it looks like this might have been fixed in the 5.3 kernel
3. suggesting to use built in driver here https://github.com/lwfinger/rtlwifi_new
4. nothing useful about RTL8822BE (mostly RTL8821 problems)
