    tl-wn422g wireless usb adapter

    I want to use tl-wn422g wireless usb adapter on fedora. The device has an atheros 5007UG chipset, supported by zd1121 driver. A driver named zd1121rw was built into the kernel. When I plug in the device, zd1211rw module gets automatically loaded.

    But I can't proceed any further. iwconfig output is
    wlan0     IEEE 802.11g  ESSID:"" 
              Mode:Managed  Channel:0  Access Point: Not-Associated  
              Tx-Power=0 dBm  
              Retry min limit:7   RTS thr:off   Fragment thr=2346 B  
              Encryption key:off
              Link Quality:0  Signal level:0  Noise level:0
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    Trying to bring up the interface using
    ifconfig wlan0 up
    gives error:
    SIOCSIFFLAGS: Connection timed out
    so, nothing can be done with this device until the interface is up.

    I have also tried the new zd1211 driver from (compact- wireless) but it gives same results.

    Any Suggestions...?

    You may not have the firmware installed, needed for the wireless to work.

    I have the firmware installed. All the files from zd1211-firmware-1.4.tar.bz2 are copied into /lib/firmware/zd1211. But still the same situation.

    Kindly review the dmesg output if needed.

    Your dmesg output has no mention of wlan0 or zd1211rw, and that is odd.

    I do see that SELinux is active. This may interfere with the wireless connection, so disable it and try again.

    Also, put a copy of the firmware directly in the /lib/firmware folder, it may not be looking for it in the /zd1211 sub-directory.

    Hi waterhead,

    Thanx for your support. I have disabled selinux and copied the zd1211 firmware in the lib/firmware directory. Now the dmesg output shows loading of zd1211rw driver.

    But still, when I try to bring up the interface, it is giving error of SIOCSIFFLAGS: Connection timed out.

    Any Idea....?

    In the future, just post the output of dmesg in your post. I would rather not have to download a zipped file from an unknown source.

    I still see a lot if SELinux messages, so it still is running. This may or maynot be your problem, though.

    Have you configured the device in the Network section? You can start it with this command:
    Click on the device and click Edit. Select Controlled by NetworkManager and use DHCP for the connection.

    Sorry for attaching the zip files. I had to do so, bcoz size of text file exceeded the allowable limit.

    Anyhow, main problem is that this device DOES NOT APPEAR in the Network configuration dialog. Even I can't add it through 'New' wizard bcoz when I click 'New' and select 'Wireless Connection', my device does not appear there. (There is only one entry 'Other Wireless Card' which shows a very limited list if wireless cards)

    You could try running the kudzu command. Try this to see if it lists the wireless card. (as root)
    kudzu -p -c network
    This only probes the system and prints out what it finds. Then just run kudzu without any options. That is suppose to configure new hardware. Then run the first command again to see if it is any different.

    Is there a configuration file for it in the /etc/sysconfig/networking or networking-scripts

    Running kudzu without any arguments and then running kudzu -p gives info about this card. (don't recognizes it as a network interface)
    class: OTHER
    bus: USB
    detached: 0
    device: wlan0
    driver: zd1211rw
    desc: "ZyDAS USB2.0 WLAN"
    usbclass: 255
    usbsubclass: 0
    usbprotocol: 0
    usbbus: 1
    usblevel: 1
    usbport: 6
    usbdev: 3
    vendorId: 0ace
    deviceId: 1215
    usbmfr: ZyDAS
    usbprod: USB2.0 WLAN
    There is no configuration file for this interface in the paths mentioned.

    You may have to try manually adding it. First, open the file /etc/sysconfig/hwconf in a text editor, as root (use su). Then try changing this:
    class: OTHER
    to this:
    class: USB
    If that doesn't work, you may need to add it to the file that lists the other network devices. The problem is, I can't find that which file it is using. You may need to make a file for it in the /etc/sysconfig/network-scripts/ and call it ifcfg-wlan0. Here is one that I have.
    # Please read /usr/share/doc/initscripts-*/sysconfig.txt
    # for the documentation of these parameters.
    HWADDR=00:00:00:00:00:00 <change this>
    ESSID=<change this>
    CHANNEL=1<change this?>
    Change the ones that I indicated. You need the MAC address for the HWADDR. I removed any info related to my wlan0 setup.

    EDIT: There seems to be an identical file in the /etc/sysconfig/network folder. Maybe you need to put a copy of it in there too.
