I got a Sony Vaio. Everything is up-to-date and I installed all the firmware.
The problem is, that I cannot connect to wifi.When I installed Kali on my laptop I used ethernet and I also got an error that "rtl_nic-rtl8168g-2.fw" is missing. I skipped it because eventhough I downloaded the file and put it on my USB it did not get noticed by the system. However, using WiFi Radar does not help at all. I can't find any routers in my environment. I guess there's something wrong with my network controller (Broadcom Corporation BCM43142 802.11b/g/n). I also tried installing firmware for my adapter.
However, if I use ifcofig there only shows up "lo" and "eth0".
If I use "ifconfig wlan0 up" when connected to the router via ethernet cable or without (doesn't matter) it says "wlan0: ERROR while getting interface flags: No such device
I just don't know what to do.
Also, I used "Legacy" instead of "UEFI" because I couldn't install Kali if it was set to UEFI.
I'd really appreciate any help
