2011-01-06 16:49:56 Need help configuring TL-WN821N USB Wifi adapter
Jay Ku (UNITED STATES)
I'm trying to get a TL-WN821N working with my board. I have an SL811 USB controller that works fine with USB flash drives. I'm using 2010R1 uclinux.
I'm following the instructions here: docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:wifi_over_usb&s=usb&s=wifi. In addition to the options listed in the wiki, I've also selected Linux Kernel->Device Drivers->Network device support->Wireless LAN->Atheros Wireless->Atheros wireless debugging and ->Atheros AR9170 802.11n USB support. This builds a driver called ar9170usb, so I've skipped the "Build TL-WN821N drivers" step in the wiki - is this ok?
I've downloaded the ar9170 drivers from wireless.kernel.org/en/users/Drivers/ar9170 and put them in /lib/firmware. Following the steps in the wiki I also put ar7010_1_1.fw in /lib/firmware. I'll figure out which one(s) I actually need later on.
When I insert the card I see it recognized:
root:/> usb 1-1: USB disconnect, address 2
usb 1-1: new full speed USB device using sl811-hcd and address 3
usb 1-1: New USB device found, idVendor=0cf3, idProduct=7015
usb 1-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48
usb 1-1: Product: UB95
usb 1-1: Manufacturer: ATHEROS
usb 1-1: SerialNumber: 12345
Then I do 'modprobe ar9170usb' which replies with 'usbcore: registered new interface driver ar9170usb'. But it doesn't actually seem to do anything - iwconfig doesn't list any new adapters.
Any help appreciated.

did you run `dmesg` to see if there was any info there ? you might want to try configuring it to work on your desktop Linux system first to work out any random kinks.
