Follow up dumb question, but I've very recently experienced (with ath(4),
however) the following:

* wlan0 is declared 'UP' and even associated, as declared by ifconfig(8)
* DHCP seems successful- wlan0 has my static reservation

However, the machine would otherwise seem to have no network. All ping(8)
packets lost, but the network is otherwise fine. Related, by chance?
