I am willing to test updates but not when it jeopardises my internet connection, LAN or DHCP. Is there a way I can connect the Deeper mini without the outbound ethernet connection? (i.e. it will not sit between my modem and router)
You can setup your mini after your router and connect the mini to a PC or laptop through an ethernet cable. This should allow you to test the device without breaking the connection to other points in your network.
