Wireless problem on F8 -- can't access secured networks



I've installed F8 on an IBM ThinkPad R40 with an IBM High Rate wireless card. The wireless card is recognized as an Atheros AR5212. NetworkManager starts up fine, and I can connect to unencrypted AP's OK (like my neighbor's), but I can't connect to protected networks (like mine).

I've previously had Windows XP then Ubuntu on this box, and neither had a problem connecting, so I am pretty confident that it's not a hardware/compatibility issue. I've configured wpa_supplicant to run via Service Configuration, which tells me that it is running. WPA passphrases seem to get stored in the keyring OK.

In attempting to troubleshoot this, here's what I've discovered. When booting, there is a fairly long delay, which causes the Details window to pop up automatically. The delay is in starting wpa_supplicant, and in fact, an error is noted:

Starting wpa_supplicant: /etc/wpa_supplicant/wpa_supplicant.conf, , dbus_bus_get[ctrl_iface_dbus]: No such file or directory

Now, there is a file /etc/wpa_supplicant/wpa_supplicant.conf, owned by root and with rw permissions for owner. I haven't touched this, and I assume it is correct. So I wonder if the dbus_bus_get[ctrl_iface_dbus] is the thing that's complaining. Searching on that string yields [1] some source code:

	/* Get a reference to the system bus */
	dbus_error_init(&error);
	iface->con = dbus_bus_get(DBUS_BUS_SYSTEM, &error);
	dbus_error_free(&error);
	if (!iface->con) {
		perror("dbus_bus_get[ctrl_iface_dbus]");
		wpa_printf(MSG_ERROR, "Could not acquire the system bus.");
		goto fail;
	}

which looks like it might print that string followed by an error, but then it should also be displaying (somewhere?) the "Could not acquire the system bus." which I haven't found.

The other data point I have is that in the system log, when attempting to connect, I see the following error msg:

Nov 18 20:56:29 think NetworkManager: <info> Device 'wlan0' DHCP transaction took too long (>45s), stopping it.

Can anyone help me get my wireless up and running on this guy? Where do I go next?
