During installation I got a few pop ups stating that hardware needs non-free firmware files to operate. At that time I didn't have those files so I continued with the installation, but now my now system is not able to recognize wifi. I tried installing firmware but whatever from searching from didn't at all work.
The missing files are:
rtlwifi/rtl8723befw.bin
rtlwifi/rtl8723befw.bin
Now I completed the installation, how can I install the firmware?
