Bug Description
Ubuntu 14.04/14.10 driver rtl8192cu for a Realtek USB wireless card is buggy. I can connect to wifi, but soon the connection is dropped.
WORKAROUND: 1. First check whether the buggy driver rtl8192cu is active in your operating system. Execute at a terminal window:
lsmod | grep rtl
2. Disconnect your wireless connection (unplug the USB adapter that contains the Realtek chipset), and temporarily connect to the internet by means of an ethernet cable (or by means of another wireless chipset that does function well).
3. Now install some applications for building the right driver via a terminal:
sudo apt-get install linux-headers-
4. Now download the source code of the driver via a terminal:
git clone https:/
5. Set it up as a DKMS module via a terminal:
sudo dkms add ./rtl8192cu-fixes
6. Build and install the new driver via a terminal:
sudo dkms install 8192cu/1.9
7. Refresh the module list via a terminal:
sudo depmod -a
8. Blacklist the faulty driver via a terminal:
sudo cp ./rtl8192cu-
9. Reboot your computer. The problem should now be solved: disconnect the temporary ethernet cable and insert the Realtek device again. With the following terminal command you can check whether the right driver is active now (copy and paste it into the terminal):
lsmod | grep 8192
Note: a possibly surprising side effect might be, that the light on your wireless card is blinking constantly now. That's normal: the light is blinking whenever data are being sent or received.
