Many thanks go out to (e:Paul) and Andy Grimm from the Fedora Project who messaged me a few days back to say that RTL8191SEvB does work with Fedora15 and offered to help.
For those of you who are stuck with this odd-man-out driver from Realtek: RTL8191SEvB and are ruing the loss of your wireless networks on Fedora15, here's the step by step guide.
1. Download the RTL8191SE driver from Get both RTL8192SE and RTL8191SE-VA2 if you are doubtful of what to get.
2. Extract it to its own directory. Navigate to that directory using the terminal.
cd /directory_you_extracted_the_RTL8191SEvB_driver
3. Try running the make command once you are in the directory:
make
4. You will see this message:
make -C /lib/modules/2.6.38.6-26.rc1.fc15.x86_64/build M=~/Downloads/rtl_92ce_92se_92de_linux_mac80211_0003.0620.2011 modules
make: *** /lib/modules/2.6.38.6-26.rc1.fc15.x86_64/build: No such file or directory. Stop.
make: *** [all] Error 2
5. Note the number in bold: 2.6.38.6-26.rc1.fc15.x86_64. Append it behind the words "kernel-devel-" and key in this command in the terminal:
This will install the tools you need to compile the kernel.sudo yum install kernel-devel-2.6.38.6-26.rc1.fc15.x86_64
6. Now in the terminal again, key in:
make
This will be followed by a ton of output and jargon mumbo-jumbo from the terminal. Once the cacophony quiets down type:
sudo make install
7. Reboot! Rejoice! Your wireless should be back.
I have finally realized that in the linux world, THIS all you need - a possibility of someone helping you out from the doldrums. If I wanted to go the roses-are-red/sky-is-blue-ad-nauseum rehash-famous-quotes route, I would say:
Making linux work = 78% dare-devilry + 22% possibility of help.
Well... you don't have to do the number matching and compiling and "running the installer" is really double-clicking and sitting bag with a bag of popcorn. I am not defending windows, I am just saying, its a lot less involved. :)
If you think about that, its not so crazy complicated. Download the sourcecode for the driver, compile, reboot. On windows you would have to download the installer, run the installer, enable driver, reboot too.
