in gui connecting , show on state bar , connecting, dhcp , all ok , but the last step done connecting failed .

then i found a method to solve the problem:

sudo leafpad /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

update_config=1

network={ ssid="wifi_name" psk="wifi_password" priority=5 }

save it may work or reboot work for me.

this doesn't seem to work, I also manage to authenticate but it doesn't connect to the network. i'm getting "scan error: (-11)" from the bcm network driver,

@bamarni @digitalgust any idea how to solve it?

[whitecider]

any progress? i am not able to connect to wifi. does seem to authenticate. not sure what digitalgust did im not an expert.

Has anyone figured out this issue? I can't connect to any wifi network, no matter what I do.
