I have had problems with the bridge freezing if the router loses sync with the exchange and then not reconnecting until I power cycle the bridge - this is very irritating as I can lose big chunks of data if I don't notice it and do a power cycle. We have a poor internet service which drops out several times a week (mainly Saturday & Sunday evenings
) I've now set up the router with a static IP address for the bridge (using the MAC address for the bridge) and the last time the router dropped its connection and resync'ed, the bridge did not freeze and reconnected itself without requiring a power cycle, so it may be worth you trying.
One would have hoped that the bridge could sort itself out without requiring manual intervention as it is supposed to be a data monitoring/gathering device.
