Unable to search for Wi-Fi

I have install Q4OS on my Macbook Air successfully. Everything works well except that the system can't search for Wi-Fi connection. When I went to settings to check the Wi-Fi, it showed that the laptop have been connected to a wired connection called "lo".
When I tried to install the corresponding NIC driver, it indicated the system had installed the NIC driver.

Re: Unable to search for Wi-Fi

"lo" is a connection called "loopback" to your computer itself, with 127.0.0.1 as IP address. If you have a web server (apache for example) running on your machine you can type 127.0.0.1 in the address bar of a web browser to get your home page.

• Which version of Q4OS and which desktop do you use?

• How did you check the Wi-Fi? Did you use the network icon in the taskbar?

• What is the output of $ sudo rfkill? (install rfkill if it is not present: $ sudo apt install rfkill).

• It could be useful to have the output of $ inxi -Fxxx (type all the commands having $ in a Konsole, without the $ sign).

Re: Unable to search for Wi-Fi

Your wireless adapter may work with newer kernel, so we recommend you to try install kernel from Debian backports:
- Add Debian backports repo:
$ sudo qrepoadd --gui
and run installation:
$ qinst-kernel-bpo

Re: Unable to search for Wi-Fi

I see that rfkill shows only a Bluetooth device, but no wlan (= Wi-Fi) device, blocked or unblocked.
