I've had several routers on which the bridges have gotten deleted somehow. Each time, the router had a bridge with Ethernet and WLAN ports on it. Users would report loss of connectivity, and when I logged into the router, the bridge was gone. The ports showed to be configured for a nonexistent bridge with a name consisting of an asterisk and a number - for example, "*8." The IP address that was assigned to the bridge also gets assigned to bridge *8. Bridge *8 doesn't really exist on the router, but the ports and IP address get assigned to bridge *8. When I create a new bridge and change the bridge interface for each port from *8 to the new bridge, and assign the IP address to the new bridge, users regain connectivity. What would cause bridges to get deleted, and cause ports and IP address reassigned to *8?
