Wireless connection drops and doesn't reconnect (netcfg, wpa_actiond)

Question

I use netcfg 2.5.4-1 and wpa_actiond 1.1-1, B43 driver (BCM4318 wireless card) with firmware.
$ uname -a
Linux vekta 2.6.32-ARCH #1 SMP PREEMPT Mon Mar 15 20:08:25 UTC 2010 i686 Mobile AMD Sempron(tm) Processor 3100+ AuthenticAMD GNU/Linux
Connecting works fine. I can connect using sudo netcfg <profile>, or it automatically connects me on startup.
However, after a few minutes (up to 15 at best, usually 3-5) the connection is dropped. dmesg prints:
"No probe response from AP <macaddress> after 500ms, disconnecting."
However, netcfg isn't notified of this event, and still thinks the profile is connected. So I have to use netcfg -r <profile> to reconnect. Isn't netcfg supposed to notice this connection drop and try to reconnect again automatically?
Also, is there any way to increase the 500ms threshold mentioned in the log? I don't think I ever had this problem when I first installed arch in november/december last year.
Thank you.

Hey,
I'm having this sort of problem with my Broadcom wireless card, in my case however the connection seems to drop after a period of inactivity. What you have done might solve my problem. So exactly what modification have you made in netcfg ?
This is the patch I made;
