    Re: how to compile a wifi driver

    I worked on this for quite a while and finally, finally got it to make and install. Perhaps some of the steps I will outline are redundant, but that's what worked for me.

    DISCLAIMER: I do not use the Realtek 8192SE, so I cannot tell if this drives the device properly; these steps merely build the module you linked.

    All the steps in 'Code' blocks are terminal commands. Please enter each individually. This assumes you have internet access on the computer on which the module is to be compiled and installed.

    Code:
    sudo apt-get install build-essential linux-source-2.6.31 linux-headers-generic
    cd /usr/src
    sudo tar -xvjf linux-source-2.6.31.tar.bz2
    sudo ln -s /usr/src/linux-source-2.6.31 /usr/src/linux
    cd ~
    mkdir Realtek
    cd Realtek
    wget http://launchpadlibrarian.net/33927923/rtl8192se_linux_2.6.0010.1012.2009.tar.gz
    tar -xvzf rtl8192se_linux_2.6.0010.1012.2009.tar.gz
    cd rtl8192se_linux_2.6.0010.1012.2009
    make
    sudo su   
    make install
    I have assumed you are running kernel 2.6.31-xx. Find out with:
    Code:
    uname -r
    It will be something like this:
    2.6.31-14-generic
    The source you need is the first part only, in this case, 2.6.31. If your running kernel is different, customize these commands to match.

    Some of these steps will take a few moments and spit out many lines of text. Please be patient. Please stop and post back with a question if you see the dreaded 'Error.' Next do:
    Code:
    modprobe r8192se_pci
    iwconfig
    Do you now have a wireless interface, wlan0, perhaps? Can you click the Network Manager and connect?

    EDIT: Added additional required packages.

    Hmm, weird, that's what I had to do with my 8192e after every reboot after I compiled and installed the drivers.

    Installed wicd instead and removed network manager, going to see if that works better next time.

    However, your error, that i don't get, gives me something else to look for and muck around with.

    Yes. On a laptop with a live usb install (for testing and wrecking things till I get it all right).

    Like I say, trying some other things now to see if I can get it to start on it's own. Not the most experienced user, but I'm not giving up!
