Hi,

I think the card stop the traffic when the signal is too weak.

I also had the same problem as you ( on i386 platform ).
So, i removed a line of /usr/src/sys/net/if.c

From the 1171 line :

	/* Notify that the link state has changed. */
	if (ifp->if_link_state !=3D link_state) {
		ifp->if_link_state =3D link_state;
		rt_ifmsg(ifp);
		log(LOG_NOTICE, "%s: link state changed to %s\n", ifp->if_xname,
		    (link_state =3D=3D LINK_STATE_UP) ? "UP" : "DOWN" );
	}


i removed the following line :

log(LOG_NOTICE, "%s: link state changed to %s\n", ifp->if_xname,
		    (link_state =3D=3D LINK_STATE_UP) ? "UP" : "DOWN" );

Now, i don't have any more this message
