GNOME GUI doesn't reckognize WiFI-Adapter.

[TeReOs]

Hey there.

So, my problem is, that I can connect to WiFi networks, using the terminal, but my GUI (Gnome) shows me, that it can't find a Wifi-Adapter.

Version:

5.2.0-kali2-amd64 #1 SMP Debian 5.2.9-2kali1 (2019-08-22) x86_64 GNU/Linux

I just installed Kali light and switched to Gnome, installing the following packages:

apt-get install gnome-core kali-defaults kali-root-login desktop-base

Im using the following, to connect to WiFi:

sudo ip link set down
sudo ip link set up
wpa_supplicant -B -iwlan0 -c /etc/wpa_supplicant.conf -Dnl80211, wext
sudo dhclient wlan0

As stated, that works, at least until I restart the system.
lspci show the following as network controller:

04:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)

I downloaded this devices drivers from the Intel site and pasted them to /lib/firmware, which also wasn't successful, after a reboot.
I tried upgrading the system and also installing the linux firmware with apt.
network-manager-gnome is also installed.

Help would be appreciated.

If You can connect usung command, try install Plasma and install plasma network manager, add it to task, and check it.

sudo apt-get install plasma-nm

What about kali live ? do u see Your wifi adapter ?

When some piece of hardware doesn't work as expected, the first reflex should ALWAYS be to look in dmesg to see if there are any error messages.

lspci is great but it only tells the presence of a device, not if a driver is loaded or if the firmware is missing.
