hostapd not sending beacons, and no traffic.

[Karl Hiramoto <karl@hiramoto.org>]

Hi,

Using hostapd from git.   I have the same thing happening with both 
wirelees-testing and linux-2.6.30-rc6


Scenario 1:   
eth0 bridged to wlan0_0.    all traffic works with no problems.   Ping 
and Lots of traffic between interfaces works fine.


Scenario 2:   
eth0 bridged to wlan0_0 in one subnet.   Then en eth1 I have another 
subnet, i route between subnets.  I can ping between subnets to for a 
while.  I can not copy a large file,  iperf also fails.   At some point 
hostapd stops sending beacons and ther is no traffic.  It seems to 
respond to probe requests.

Senario 3:   
Same as senario 2 but NAT instead of route.
eth0 bridged to wlan0_0 in one subnet.   Then en eth1 I have another 
subnet, I NAT/ MASQUERADE  between subnets.  I can ping between subnets 
to for a while.  I can not copy a large file,  iperf also fails.   At 
some point hostapd stops sending beacons and there is no traffic.  It 
seems to respond to probe requests.



Hostapd configuration:

interface=wlan0_0
bridge=br0
driver=nl80211
logger_syslog=-1
logger_syslog_level=2
logger_stdout=0
logger_stdout_level=2
dump_file=/tmp/hostapd/hostapd.0.dump
ssid=karl

hw_mode=g
auth_algs=1
macaddr_acl=0
accept_mac_file=/tmp/hostapd/hostapd.wlan0_0.accept
deny_mac_file=/tmp/hostapd/hostapd.wlan0_0.deny
ignore_broadcast_ssid=0
wpa=3
wpa_passphrase=hiramoto
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
ieee8021x=0

Any ideas on where the problem could be?

Thanks.
