How to make TP Link TL-WN721N Wireless card work in RHEL 6.4?
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
usb 1-5: New USB device found, idVendor=0cf3, idProduct=9271

Hi Siddarth. Probably the first step would be to ensure that the wireless hardware is supported. Opening a support case with Red Hat should resolve that pretty quickly for you.
Otherwise maybe one of our users has had experience with this particular card an might be able to shed some light on your issue.
