Hello, I have installed FreeBSD-9.0-RC3 on my Thinkpad X61, which has Intel 4965 Wifi card, and the installer sets up wireless network using wpa_supplicant. It works after the rebooting, but after some minutes without using wlan it doesn't. To make it work again,
# dhclient wlan0
must be invoked. I have tested it on FreeBSD-8.2-Release, but no difference. What exactly cause this problem and how to solve it?
