Realtek RTL8191SEvA Wireless in Fedora

UPDATE: The information below will still work on older kernels, but it appears that as of Fedora 15′s kernel 2.6.40-4.fc15, there is in-kernel support for this wireless chipset. Not sure if/when this will show up in RHEL/Centos/Fedora 14, but if you’re on F15, just update your kernel. See here for more info. (Note: Kernel 2.6.40 contains a lot of features from mainline 3.0, so no need to update to Rawhide 3.0.)

 

We’re rolling out a bunch of Fedora-based thinclient-like devices at work that contain a RTL8191SEvA chipset. Unfortunately, this isn’t built into the kernel as of 2.6.38.8-32.fc15 (I think there are licensing issues at play), so it has to be compiled and inserted by hand.

The official device listing is:

# lspci | grep Realtek
Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvA Wireless LAN Controller (rev 10)

You can find the driver here. Note that for the RTL8191SEvA chipset, you need the RTL8192SE driver, not the RTL8191SE-VA2 driver. Download it and extract it.

# tar -xvzf rtl8192se_linux_2.6.0019.1207.2010.tar.gz

Go in to the directory and compile it.

# make && make install

When it’s finished, you’ll have the module kernel/drivers/net/wireless/r8192se_pci.ko

Then, use modprobe to insert it.

# modprobe r8192se_pci

You can check to make sure it’s loaded by hitting up lsmod. After that, check ifconfig to make sure the device is listed.

# lsmod | grep r8192
r8192se_pci           472218  0
# ifconfig | grep wlan
wlan0     Link encap:Ethernet  HWaddr 1C:65:9D:7B:13:A7

If you want to uninstall it, go back to the extracted folder and run

make uninstall

While not exactly complicated, the confusion in the drivers on their page tripped me up for a bit. If this helps you, feel free to drop a comment and let me know.

  1. thanks very much it worked for me

  2. hi, I have this card RTL8191SEvA aswell in my hp notebook. I have ubuntu installed. Can I aircrack with my wireless card and be connected to the internet at the same time on the same card?

    also if so ill download the driver listed correct?

    • To be honest I don’t know, as I don’t use Aircrack. A simple Google search and quick rundown of the wiki@Aircrack didn’t bring anything up. My assumption would be you can, but then again you may run into an issue with dropped packets due to flooding.

      I really don’t know, you’ll just have to try and see.

      Also, if you’re using the latest Ubuntu, this driver is probably already included in the kernel, if it’s >3.0.

  3. looking for user and password from realtek to download drivers from their site as i am prevented from downloading

    • You shouldn’t need a username and password to download from the link I provided in the article. Additionally, that is now old information. As posted in bold at the very top of the article, if you have any kernel from at least the last two years or so, that driver (or at least an open version) should be included in the kernel.
