So, does it mean that driver is installed successfully? But iwconfig gives nothing for wlan0 again. Help me, please, avoid going back to Windows...

You installed the rtl8192cu driver correctly but no wireless interface was created because rtl8192cu is incorrect for your device. Please get a temporary wired ethernet connection and do:

sudo apt-get install git
git clone https://github.com/purchae/rtl8188eu.git
cd rtl8188eu
sudo make install
sudo modprobe -r rtl8192cu
sudo modprobe 8188eu

When a later kernel version is installed by Update Manager, after the required reboot, re-compile:

cd rtl8188eu
make clean
sudo make install
sudo modprobe 8188eu

I have the same D-Link DWA-125 rev.D1, but



Bus 001 Device 005: ID 2001:3310 D-Link Corp. 

(pay attention to the ID)

And to make it work I change file rtl8188eu/os_dep/usb_intf.c

-       {USB_DEVICE(0x2001, 0x330F)}, /* DLink DWA-125 REV D1 */


+       {USB_DEVICE(0x2001, 0x3310)}, /* DLink DWA-125 REV D1 */

save it

sudo make
sudo make install
sudo modprobe -r 8188eu
sudo modprobe 8188eu

and now driver works for me :)


The biggest thanks to you. Finally driver is installed. The only thing is that dongle doesn't work properly: after 7-10 seconds of downloading-nothing-or-nothing-doing-in-internet, icon in tray shows "no signal", ping goes to limitless.

Only by case I mentioned that if I start download something really big, my good internet exists as long as downloading process longs. What have I done wrong? Btw, in Windows it works perfect.

  • Copy and paste this command in the terminal (ctrl+alt+t)wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script It will download a script and create a file named wireless-info.tar.gz in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security,paste contents of the wireless-info.tar.gz file as a zip file at pastebin.com.

  • pastebin.com/hZRVxj60 - when something big is downloading, pastebin.com/1eqdSXyk - when nothing's done with computer for over 30 seconds.
