Device Connector IP55 (WiFi Bridge) - 2 connections, load balanced

If using the Device Connector IP55 (WiFi Bridge) with a Peplink router

a) Is there any way to manage the WiFi it sees from the router rather than the bridge?

b) If the device is connected to 2 different WiFi connections (2.4 & 5.8), how can the router see both to bond them together?

Thanks
Paul
