When I was installing the system I could connect with the adapter to my networks, I used Debian 9 non-free firmware version. But now with the network manager from KDE or Gnome, it doesn't possible connect.
I can connect with wpa_supplicant directly from the console using the settings remarked in this web page: https://shapeshed.com/linux-wifi/ and setting the driver to nl80211 or wext. If I don’t set this driver in the wpa_supplicant -D parameter I cannot connect anyway, basically doing:
Code: Select all
wpa_supplicant -i wlx00c0ca9233e3 -c /etc/wpa_supplicant/wpa_supplicant.conf -D nl80211
Code: Select all
wpa_cli
I found this temporary solution but at this stage, I don’t know why works and it is not a comfortable alternative for me because I cannot connect to the desired network on the fly later the system is started:
Code: Select all
/etc/network/interfaces:
auto wlx00c0ca9233e3
iface wlx00c0ca9233e3 inet dhcp
wpa-driver nl80211
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
Code: Select all
/etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/run/wpa_supplicant
update_config=1
network={
ssid="10"
psk="password"
}
Code: Select all
dhclient -r
dhclient wlx00c0ca9233e3
I researched how I can set the network manager using the nl80211 driver to be connected, I “think” this is the issue, but until now I don’t find the way to do it.
I need help, how can I found what is the exact conflict?
