Hi.

I have ThinkPad X1 laptop with iwn(4) network card.

%uname -spr
FreeBSD 9.0-RC1 amd64

% dmesg 
iwn0: <Intel(R) Centrino(R) Wireless-N 1000> mem 0xf2500000-0xf2501fff irq 17 at device 0.0 on pci3

>From time to time it works well, i.e. on my job, but currently it doesn't work
with my small home WiFi/ADSL router D-Link G-604T.
Also, in my home network I have two different devices: Galaxy Tab and MacBook Pro 15" and
these devices are works well, but ThinkPad with FreeBSD 9.0-RC1 can't connect to WiFi router :-(

Also, I tried to use Ubuntu Linux 11.10 LiveCD and the laptop works well with
home WiFi network.

In /etc/wpa_supplicant.conf I have two network entries (for home and for job) with
psk keys.

$ more /etc/rc.conf

ifconfig_wlan0="WPA DHCP"
