In a caravan on a campsite, I have a Ubiquiti NanoStation M2 long-range Wifi router which picks up the campsite's Wifi AP. The M2 provides an Ethernet connection to my laptop, and internet access is good. Now, I want to connect this Ethernet cable to the WAN port of a DI-634M wifi router in order to create a local wifi network around the caravan. I cannot work out the settings needed in both routers to make this work! Any ideas?
