For your wireless, run your terminal and type

iwconfig

and if you get lines that print "No wireless extensions." then your wireless card may either not be enabled or configured.
If, on the off-chance, that it's disabled, type in the terminal

sudo ifconfig wlan0 up

and try iwconfig again and see if that works.

when i type iwconfig i got :

l0 no wireless extensions.

eth0 no wireless extensions.

wmaster no wireless extensions.

Is your user a member of the audio group? You need to be a member of the audio group for alsa to work. You can check this using the command groups. If you are a member of the audio group, you need to find out if the device is detected with the command lspci | grep -i audio.
