    Default TP-Link TL-WN821N

    Have the above USB Wireless adaptor. Info:
    UDI: /org/freedesktop/Hal/devices/usb_device_cf3_1002_12345_if0

    From dmesg:
    usb 1-4: configuration #1 chosen from 1 choice
    usb 1-4: New USB device found, idVendor=0cf3, idProduct=1002
    usb 1-4: New USB device strings: Mfr=16, Product=32, SerialNumber=48
    usb 1-4: Product: USB2.0 WLAN
    usb 1-4: Manufacturer: ATHER
    usb 1-4: SerialNumber: 12345

    From what I have read, this is supported by the latest drivers, and in the latest kernel....
    As I don't have the latest kernel (2.6.27.29-0.1-default) I have downloaded the latest drivers and firmware(ar9170) and installed (I think!) successfully. But, I think it is supposed to give me an ar9170usb driver(??), but this doesn't exist. There appears to be no real howto for this (that I can find).
    Where can I find the actual driver...?

    Thanks,
    John.

    knowing about one's system is normally helpful;

    run this script

    Benutzeranleitung/Usersguide von/of collectNWData | collectNWData.sh

    and post the results back to the forum;

    (the script may even give you the answer ...)

    the script is safe and has been used many times on this forum; it is written by framp in Germany

    Have you installed the compat-wireless package for your kernel? It was
    not clear what you did when you said you downloaded the "latest drivers".

    Yes, I did install the relevant compat-wireless package, and it all seemed to install OK.

    I don't understand why the driver is not loading. Please run the
    following command and post the output:

    Code:
    find /lib/modules  -name  "ar9170*.ko"
    I think ar9170usb.ko is the correct driver.

    Running find /lib/modules -name "ar9170*.ko" gives no output...
    I'm back home, so versions are:
    john@boss:~> uname -r
    2.6.27.29-0.1-default

    The Compat stuff I installed was: compat-wireless-2.6.30.tar.bz2
    Just did a full search of the PC, and there is no file ar9170* at all - except the firmware....

    John.

    That certainly explains why the driver is not loading. That version of
    compat-wireless is too old. You should either get the current
    "bleeding-edge" version or the correct compat-wireless package for
    your kernel. If I remember correctly, it is located in the Packman
    repository. I'm running 11.2 now and cannot check the 11.1 repos.

    config.mk:

    a) compat-wireless STABLE(2.6.30)

    Code:
    # Activate AR9170 support only on kernel >= 2.6.29.
    # The needed USB poison feature was added in this kernel release.
    ifeq ($(shell test $(KERNEL_SUBLEVEL) -ge 29 && echo yes),yes)
    CONFIG_AR9170_USB=m
    CONFIG_AR9170_LEDS=y
    endif
    b) compat-wireless "bleeding edge" (2.6.32-rcX)

    Code:
    ifndef CONFIG_COMPAT_WIRELESS_28
    CONFIG_AR9170_USB=m
    CONFIG_AR9170_LEDS=y
    endif

    Now I am getting REALLY confused. If I download the bleeding Edge, there is still no usb driver:

    boss:/home/Software/wireless/compat-wireless-2009-10-24/scripts # ./driver-select
    Usage: ./driver-select [ <driver-name> | <driver-group-name> | restore ]
    Supported drivers:
    ath5k
    ath9k
    ar9170
    zd1211rw
    Supported group drivers:
    atheros < ath5k ath9k ar9170 zd1211rw >
    ath < ath5k ath9k ar9170 >
    intel < iwl3945 iwlagn ipw2100 ipw2200 >
    iwlwifi < iwl3945 iwlagn >
    rtl818x < rtl8180 rtl8187 >
    wl12xx < wl1251 (SPI and SDIO) wl1271 >
    Restoring compat-wireless:
    restore: you can use this option to restore compat-wireless to the original state


    If I try and install through Yast, I get:
    nothing provides kernel(default:vmlinux) = f30985aa0d58b1bd needed by compat-wireless-kmp-default-20080615_2
    but:
    boss:/home/john # uname -r
    2.6.27.29-0.1-default


    What next?
    BTW, appreciate all the assistance!
    Thanks, John.
