I just bought a new HP laptop just for the purpose of installing and learning Kali linux. It had originally windows 10 installed in it. I downloaded and installed the latest version of kali linux. Everything seems to be good and working but when I tried to connect to internet, I can't to it. I can just connect using wired connection. For wireless connection, it says no wifi adapter found. I did not install kali on any virtual machine, my pc is a pure kali linux now straight booted in the drive.
When I type iwconfig in the terminal, it just shows me eth0 and lo. It doesn't show wlan0. I tried looking for solution for a whole day now. I tried a method, "download compact wireless" that everyone was showing, I was able to get wlan0 and wlan1, but now the problem is it doesn't detect any wifi. Also when I reboot my laptop, it is gone and I have to do it again, its not saved.
I have also realised that bluetooth is also not working. However, the download compact wireless method seems to fix the bluetooth, but ita gone at restart. There are people who said I need to get an adapter, but the laptop should have build in wifi card right? And I directly booted up in the machine, not in any virtual box, so do I really need to buy one? Whats the point of me buying a new laptop just for Kali? Please help me.
