/tmp/bridge_config_ath0 sets MTU 0

JTY

This is probably nothing, but thought it's worth mentioning. In the debug log /tmp/bridge_config_ath0, pfSense appears to be trying to set the MTU for both interfaces to 0. From what I can gather, pfSense is suppose to be setting the MTU on both interfaces to the same value.

/sbin/ifconfig ath0 mtu 0

/sbin/ifconfig re0 mtu 0

/sbin/ifconfig bridge0 create
/sbin/ifconfig bridge0 addm ath0 addm re0 up

Thats very strange. I've commited code to detect an MTU of 0 and simply use 1500.

I've updated to the latest snapshot, and it's still happening. As well, I checked the logs, and didn't see any error.

You must have caught a snapshot before it was included then?

I last updated to pfSense-Full-Update-1.2.1-RC1-20080730-2326.tgz. And, checking in /etc/inc/interfaces.inc, I can see the check you added.

Try changing that blob of code to:

		/* force all bridged interfaces to use same mtu */
		$mtu = get_interface_mtu($config['interfaces'][$lancfg['bridge']]['if']);
		if(intval($mtu) == 0) {
			log_error("An error occurred while trying to obtain the MTU setting.  Using 1500.");
			$mtu = "1500";
		}

Also found the problem in pfsense_utils.inc. Try the next snap.

I checked my /tmp/bridge_config_ath0

/sbin/ifconfig ath0 down
/sbin/ifconfig ath0 mediaopt hostap
/sbin/ifconfig ath0 mode '11g'
/sbin/ifconfig ath0 channel '1'
/sbin/ifconfig ath0 -mediaopt turbo
/sbin/ifconfig ath0 ssid 'TAMU'
/sbin/ifconfig ath0 -hidessid
/sbin/ifconfig ath0 -mediaopt adhoc
/sbin/ifconfig ath0 protmode 'rtscts'
/sbin/ifconfig ath0 mode 11g pureg
/sbin/ifconfig ath0 -apbridge
/sbin/ifconfig ath0 wme
/sbin/ifconfig ath0 authmode open wepmode off
/sbin/ifconfig ath0 txpower '99'
/sbin/ifconfig ath0 mtu 1500
/sbin/ifconfig ath0 up
/usr/sbin/hostapd -B /var/etc/hostapd_ath0.conf

ifconfig ath0 shows mtu as 2290

I am not in bridge mode at all.

Edit: When I first checked the logs apbridge was enabled. I don't know what that does but I disabled it and still get mtu of 2290.

Edit:Edit: apbridge is Allow intra-BSS communication when operating as an access point
