I installed Kali Linux on my Sony Vaio laptop (model number SVF142C1WW), but I had no wireless out of the box. Ethernet works fine, and I can connect to wireless networks normally from Windows running on the same machine.
$ cd desktop $ cd filenameofthatextracted folder $ make unload $ make load
After these commands, my wireless NIC seems to be recognized (see
iwconfig output below), but I can't see any available wireless networks. Also, the driver disappears after restarting, and I have to run the commands again and reinstall to get the NIC to show up in

I found one more thing, and now I'm totally confused...
See, while installing Kali Linux this is the menu you get in the beginning:
Kali - boot Non Persistent Mode Kali - Boot Persistent Kali - Failsafe Kali Forensics - No Drive or Swap Mount Kali Graphical install Kali Text install
I went into the option Kali Graphical Install to install Kali Linux.
I believed to run live Kali, and I have to go in Kali - Boot Persistent. I went into that, and I got Kali desktop. And I found out that Wi-Fi drivers were perfectly fine and they were working well. I can connect to any Wi-Fi connections and all Wi-Fi connections were showing.
What is this?
And there is one more thing. While installing Kali Linux, inbetween I got an error message saying the following...
[!DETECT NETWORK HARDWARE] Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media such as a USB stick or floppy. The missing firmware files are: rtl_nic/rtl8168e3.fw
But after I ran some update and upgrade commands, it is present in
