I'm stating in Ubuntu and I couldn't config my pci wifi card. It is seeing my network, but, when I call to connect it runs for fews seconds trying to connect and call again for the password (the password is writted right...).

My device is a Tp-link Wn881wd Atheros AR9287.

When I look at terminal "lspci" it returns the informations about the hardware.

I follow the @Otacon answer Example @otacon but at the step of run the "wpa_supplicant" it show this message bellow. Any tip?

#my terminal response to "wpa_supplicant -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_conf.conf"

root@isaque-desktop:/home/isaque# wpa_supplicant -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_conf.conf

Successfully initialized wpa_supplicant

Could not read interface wlan0 flags: No such device

WEXT: Could not set interface 'wlan0' UP

wlan0: Failed to initialize driver interface

In 16.04 the default wlan0 device does not exist, instead there is some fancy name like wlp2s0. Use this command to determine your wlan interface name:

ifconfig

After that correct your wpa supplicant init command:

wpa_supplicant -D wext -i  wlp2s0 -c /etc/wpa_supplicant/wpa_conf.conf

Remember, the wlp2s0 interface name comes from your ifconfig command, change it accordingly.
