How to make TP Link TL-WN721N Wireless card work in RHEL 6.4?

Latest response

Hi all,

I have installed RHEL 6.4 WorkStation in my PC. It works fine, except that I have a Wireless USB card TP-LINK TL-WN721N which does not work at all.

the output of dmesg is:

usb 2-1: new high speed USB device number 2 using ehci_hcd
usb 2-1: New USB device found, idVendor=0cf3, idProduct=9271
usb 2-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48
usb 2-1: Product: USB2.0 WLAN
usb 2-1: Manufacturer: ATHEROS
usb 2-1: SerialNumber: 12345
usb 2-1: configuration #1 chosen from 1 choice

I tried installing the atheros firmware for the device (htc_9271.fw) in /lib/firmware, but to no avail. I tried ndiswrapper, but that too is not working out.

output of dmesg with ndiswrapper:

usb 1-5: new high speed USB device number 4 using ehci_hcd
