Hi there,
I have a Thinkpad T41 with FreeBSD 7.2/i386
With dmesg i see the wlan card:
ath0: <Atheros 5212> mem 0xc0210000-0xc021ffff irq 11 at device 2.0 on
pci2 ath0: [ITHREAD]
ath0: WARNING: using obsoleted if_watchdog interface
ath0: Ethernet address: 00:05:4e:48:14:ab
ath0: mac 5.6 phy 4.1 5ghz radio 1.7 2ghz radio 2.3
I read the handbook, and this is me /boot/loader.conf:
if_ath_load="YES"
wlan_scan_ap_load="YES"
wlan_scan_sta_load="YES"
wlan_wep_load="YES"
wlan_ccmp_load="YES"
wlan_tkip_load="YES"
This entry i made in the rc.conf for the ath0:
ifconfig_ath0="inet 192.168.0.13 netmask 255.255.255.0"
Now ifconfig ath0 say:
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500 ether 00:05:4e:48:14:ab

and this is me /etc/wpa_supplicant.conf:
network={
ssid="linksys_SES_29944"
psk="xxxxxxxxxxx"
}
ifconfig ath0 list scan found me accesspoint:
linksys_SES... 00:06:25:4b:0d:95 11 54M -73:-96 100 EP WPA
Now I connect:
goofy# wpa_supplicant -i ath0 -c /etc/wpa_supplicant.conf
Trying to associate with 00:06:25:4b:0d:95 (SSID='linksys_SES_29944'

ifconfig ath0 say, I am connected:

but, now ping, now open a Internetsite in firefox, nothing.
But i can go for a DHCP-IP:
goofy# dhclient ath0
DHCPREQUEST on ath0 to 255.255.255.255 port 67
DHCPACK from 192.168.0.2
bound to 192.168.0.234 -- renewal in 43200 seconds.
When I ping the DHCP-Server 192.168.0.2, i have 100% packet loss.
The Laptop works finde with LAN, but not with WLAN.
