Hi, I'm running FreeBSD 8.1-Release with ath0 card. For some unknown reason this laptop is not able to get IP address from my access point (DHCP) if WPA encryption is enabled. The tricky part is that it says it is associated but has IP of 0.0.0.0. So it looks like encryption part is working and then other communication fails. Everything works fine if I switch the encryption off. The same station works fine with other access points. Other operating systems works fine on the same station with the same access point. And the same access point works fine with other stations. In short - it's only FreeBSD that is having problems in this setup. What I have tried and it didn't help: - using FreeBSD 8.0-R and 8.1-R - using isc-dhcp41-client and isc-dhcp31-client from ports - turning on/off different QoS settings on the access point - adding my station to static IP table on the access point - configuring ip address, netmask and routing table manually on my station with DHCP server both enabled and disabled - using different access points - two out of four are not working, all different makes and models Here is what tcpdump says about it (192.168.0.1 is my access point): 00:17:09.671578 EAPOL key (3) v2, len 117 00:17:09.671770 EAPOL key (3) v1, len 117 00:17:09.680168 EAPOL key (3) v2, len 151 00:17:09.680275 EAPOL key (3) v1, len 95 00:17:09.731370 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:26:5e:e7:e8:78 (oui Unknown), length 300 00:17:14.732238 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:26:5e:e7:e8:78 (oui Unknown), length 300 00:17:14.737050 ARP, Request who-has 192.168.0.50 tell 192.168.0.1, length 46 00:17:20.732593 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:26:5e:e7:e8:78 (oui Unknown), length 300 00:17:20.737266 ARP, Request who-has 192.168.0.50 tell 192.168.0.1, length 46 00:17:26.733269 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:26:5e:e7:e8:78 (oui Unknown), length 300 00:17:26.738084 ARP, Request who-has 192.168.0.50 tell 192.168.0.1, length 46 00:17:41.733600 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:26:5e:e7:e8:78 (oui Unknown), length 300 00:17:41.738351 ARP, Request who-has 192.168.0.50 tell 192.168.0.1, length 46 I'm quite desperate to get it fixed so any ideas/suggestions appreciated.
