Dear Friends,
I am fairly new to Fedora and I have Fedora 13 and I have a USB wireless card (TL-WN821N) which I would like to install MadWifi Driver for it.
Would you please help me on this.
Thank you in advance,

Madwifi is deprecated and shouldn't be needed for this card.

It looks like the driver for this card is ar9170. Plug in the device and check the output of

Code:

lsusb

to confirm.

The usbid should be 0cf3:1002.

You'll need firmware, which should be available in the Fedora repositories.

Dear reed9,
Thanks a lot. It's working now. There is One more thing if you can help me please. I have a built in WLAN card in my laptop (Intel Wifi link 5100) and in order not to use it I turned off the switch on the laptop but when I do that both Wlan cards will be disabled and I can't work with the USB wlan card only unless I turn on that Switch which cause both Wlan cards to work and I dont want that. I only want to use the USB wlan card.
Thank you in advance,
Best Regards,
dbboy

Seems odd that the kill switch for the onboard card would turn off the USB card too, but anyway.

I suppose you could blacklist the driver for the intel card. Add a line to /etc/modprobe.d/blacklist.conf reading blacklist iwlagn. You can do so as follows

Code:

su -
echo "blacklist iwlagn" >> /etc/modprobe.d/blacklist.conf

That should prevent it from loading at boot. Make sure you use two >>, just one and you'll overwrite the file.

Check that it's not loading when you reboot

Code:

/sbin/lsmod | grep iwl

No output means it isn't there.
