I'm having some problems with hostapd and bridging a wireless to a wired network that are driving me insane! I'm running Debian Sarge with a 2.6.8-2 kernel and an Atheros chipset on the wireless card.
I'm able to bring up the access point with
#iwconfig ath0 essid cabe and connect to it, but I cannot ping another computer on the wired network. It's as if the bridge is not working. However, by some miracle I DID have hostapd working at one point, and at the time I could ping a wired machine from the wireless and vice versa. I have no idea why hostapd broke but now every time I try to run
#/etc/init.d/hostapd start I get
Starting advanced IEEE 802.11 management: hostapd...failed. I've looked in both the /tmp/hostapd.dump and /var/log/daemon.log files but there is nothing, even when debug=4 in hostapd.conf. I have started with a completely default hostapd.conf, only changing the ssid, driver, and adding in the bridge var (this was not in the original hostapd.conf, but somewhere in my many painful hours of reading about this topic it was suggested that this var is required so hostapd will know it's part of a bridge).
I am at my wits end with this and am about to kill someone, so please help reduce the homicide rate and overpopulation of the jail system by helping me figure this out!
