Hi,
I'm on a fully updated Arch 64b.
Just bought this http://www.tp-link.com/products/product … =TL-WN821N 802.11n USB adater which works fine under Windows.
How can I configure my Arch accordingly?
thanks
Best regards,

What have you tried yourself so far? Linking to manufacturer pages doesn't help, 99% of the time they don't mention the chip they use. You need to find out what chip is in it and go from there.

According to this
http://en.gentoo-wiki.com/wiki/TL-WN821N
it has an atheros chipset.
Try to load ar9170usb, it is in the kernel.
After that it should show up with ifconfig/iwconfig.

Possibly easiest is to install networkmanager and see if it works out of the box.
Also as mentioned above output of lsusb might help others help you.

I have one of those. It worked out of the box (using wicd, but plain iwconfig / ifoncfig / wpa_supplicant tested & working too). Don't even have madwifi or anything installed.

Thanks all.
lsusb confirmed chip type as:
Bus 003 Device 004: ID 0cf3:1002 Atheros Communications, Inc. TP-Link TL-WN821N v2 [Atheros AR9001U-(2)NG]
Here's a copy from terminal:
modprobe ar9170usb
[root@myhost miki]# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
I've been using KDE's network manager in the first place, yet, even after loading above module, NM still displays the interface as unavailable.
I've the latest Arch kernel -see here:
uname -a
Linux myhost 2.6.36-ARCH #1 SMP PREEMPT Sat Jan 8 14:15:27 CET 2011 x86_64 AMD Phenom(tm) II X6 1055T Processor AuthenticAMD GNU/Linux
Any ideas?

See if dmesg contains any errors regarding your driver, this will tell us more about the issue.
You can also try carl9170 driver: https://wiki.archlinux.org/index.php/Wireless#carl9170 , it also supports USB Atheros chips.
