Bug Description
WLAN didn't work out of the box. After installing still no function.
WORKAROUND: To fix it I needed to add 0bda:819a by hand like descripted in:
http://
Unzip the driver and install it by hand
$cd RTL8188C_
$make
$sudo make install
$ modinfo 8192cu | egrep 'versi|filen|819'
filename: /lib/modules/
version: v3.4.4_
srcversion: FBF2DAF9D4C1BB7
alias: usb:v0BDAp8191d
vermagic: 3.2.0-36-generic SMP mod_unload modversions
parm: rtw_chip_
for the next step I needed vendor:product ID from lsusb:
$lsusb
Bus 001 Device 006: ID 0bda:819a Realtek Semiconductor Corp.
and then add this ID like here:
$ echo 'install 8192cu modprobe --ignore-install 8192cu ; /bin/echo "0bda 819a" > /sys/bus/
install 8192cu modprobe --ignore-install 8192cu ; /bin/echo "0bda 819a" > /sys/bus/
$ sudo modprobe -v 8192cu
install modprobe --ignore-install 8192cu ; /bin/echo "0bda 819a" > /sys/bus/
insmod /lib/modules/
