    Wireless internet doesn't work, blacklist?


    Hi everyone,

    I've just installed Kubuntu 8.10 and I'm really new to linux so the way it works is still a big mystery to me. So forgive my question please.

    I was having trouble with my atheros wireless driver, and someone told me how I could get another one.
    Anyway, one of the steps was this:

    echo 'blacklist ath_pci' >> /etc/modprobe.d/blacklist

    Not that I know much, but now it seems my atheros wireless is on a blacklist and can't be used? Am I right?

    So, how do I:

    (1) Unblacklist it and use it. (Keeping in mind I know little about linux, kubuntu and the whole command line thing, for now).

    or

    (2) Get a new driver that works better.

    The reason I wanted to change the driver was that when I went to use XP, then went back to Kubuntu - I could not see in network manager my wireless connection.

    This is the wireless model I have:
    0a:03.0 Ethernet controller [0200]: Atheros Communications Inc. AR2413 802.11bgNIC [168c:001a] (rev 01)

    So any help on getting my wireless internet up and running again is much appreciated, I'd hate to have to go back to xp. Just the thought of it.. shudder.


    Thanks!

    First, if you want to remove a listing from the blacklist file, you can do so with a text editor like gedit. The blacklist file is really just a text file that is usually located in the /etc/modprobe.d/ folder. To edit it, you need root privileges, so use sudo.
    Code:
    sudo gedit /etc/modprobe.d/blacklist
    You should find the blacklisted module that you added, at the bottom. Remove it and save the file.

    Now, the latest kernels contain new Atheros drivers ath5k/ath9k. One of them may be automatically loading for your wireless card. Look for it in the output of this command.
    Code:
    lsmod
    The ath_pci driver is usually not included by default. So if it is loading, it is because you added it after installation. It usually is the driver that works the best, so you would want to blacklist the ath5k driver, not the ath_pci driver.

    I recently tried Fedora 9 0n my Eee Pc with an Atheros wireless ar242x. The Madwifi driver (ath_pci) didn't work, and eventually the ath5k driver decided to work. So, you may need to play around with this. I would recommend trying to get the native driver to work first, whatever that may be. Post the output of lsmod and I'll take a look.

    Thanks for the quick reply.

    I tried sudo gedit /etc/modprobe.d/blacklist and the terminal told me " sudo: gedit: command not found"

    And here is the output from lsmod:

    You can install gedit through apt, but I just realized that you are using Kbuntu, so kwrite should be installed. Use that instead.
    Code:
    sudo kwrite /etc/modprobe.d/blacklist
    I don't see any wireless modules, so see if Kbuntu has one to install. In the main menu, look for "Hardware Drivers Manager". It should be under the "System" section. It may have a wireless driver just waiting for you to enable it. You will need a wired internet connection, because it will download and install the driver.

    Thanks for the reply.

    I just unblacklisted the ath_pci

    but it still doesn't work.

    I looked in my hardware drivers manager and it was sitting there, I clicked activate but nothing happened.

    I tried reboot, then activate - still didn't work?

    You need to put a check in the box under the "Enabled" category. You also need to have a wired internet connection, because it needs to download and then install the driver.

    Once you have it installed and enabled the driver, the "Status" category will change to "In Use" or something similar.
