FreeBSD
>Environment:
Any recent HEAD is fine. These tests have been done with r214406 (21 Oct 2010) but the HAL and net80211 layer hasn't changed since then. The problem exists with the latest HEAD.
>Description:
Clients can associate to an 11g interface but can't pass broadcast/multicast traffic.

It's related to broadcast traffic.

* Broadcast DHCP traffic from the laptop -> AP works
* AP sends DHCP request
* AP receives a DHCP reply, broadcast
* AP sends DHCP reply to the client
* client never receives reply

When the laptop in question is given a static IP address

* network connectivity to the internet (ie, out the default route) works fine
* broadcast pings from laptop -> network can be seen by the AP
* broadcast pings from AP -> network (ie, the laptop should see it!) aren't received
