FreeBSD wireless connection problems

Ladies and Gentlemen,

I have a development box which is connected to the wireless network  
via an Intellinet wireless bridge.  Periodically, the development box  
will no longer pass data on the network.  However, checking the access  
point, I can see the bridge is still associated with the access point  
and is reporting the correct IP address.

I am running FreeBSD 7.2 on the development box, running the em driver  
for the network card.  The wireless bridge is connected via an  
ethernet cable to the em0 interface.
The wireless bridge is an Intellinet Wireless LAN Base Stand set to  
Bridge in Infrastructure mode.
The access point is a Cisco 1131AG with 3 vlans.  Only the guest SSID  
is not hidden.  I am not connecting to the guest SSID.

At first I thought this was a problem with the wireless bridge.   
However, connecting the bridge to a Windows box yields a stable  

If I disable ARP Caching on the access point, clear the arp cache, and  
then re-enable ARP caching, (dot11 arp-cache optional) the system will  
reappear on the network.

I have upgraded to the latest/greatest IOS for the access point  
without any improvement.

Any suggestions would be greatly appreciated.
