I have a D-Link DWA-130 rev E1 with a RTL8191SU chip set. Under Ubuntu 14.04 it will connect to the router occasionally, most of the time it tries and fails over and over. It seems to connect with out issue on one of my machines that is running 12.04. Any help would be appreciated.

  • I am still have a problem with the dongle. I can connect to a g router OK and it works fine. When I connect to an N router, it stays connected but throughput stops for a time and then it starts again.

You can install a good driver by running

sudo apt-get install git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

Then reboot.

You will need to install it after each kernel update. You can keep rtlwifi_new folder and just run last 3 commands.

In case you have no other way to get internet connection, you can download this driver in Windows or using another computer. Do it this way:

  1. Download the driver AS A ZIP ARCHIVE.

  2. Extract it to your home directory. You will get rtlwifi_new-master folder there.

  3. Run in terminal:

    cd rtlwifi_new-master
    make
    sudo make install
    sudo update-initramfs -u

I made this driver as a DKMS module and added it to ppa.

If the driver is installed from ppa, it will rebuild after each kernel upgrade. Install it this way

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms

For Ubuntu 14.04 users, if there are still issues I recommend to install new linux-firmware backported from 15.04. It contains new firmware for various devices, including Realtek wireless.

It can be installed from same repository by

sudo apt-get install linux-firmware
