I Can't Connect To `Wifi` When I Type `ifconfig` wlan0 up it shows `wlan0: ERROR while getting interface flags: No such device` i tried solutions like re-installing `firmware-b43-installer` , installing `wicd` downloading Broadcom packages But it Doesn't seem to work. I Have a Breadcom bcm43142 and when I Type `ifconfig` it shows
