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 connection. 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. Thanks, Jay
