I made some mistake when initially setting up the AP which has left me unable to communicate with it. I've tried factory resetting the unit by holding in the tab (adjacent to the Ethernet port) for 10, 20, 30 seconds. But nothing returns it to it's default IP (192.168.0.1). I'm not sure how to proceed from here.
By pressing down the reset tab on the Access Point for about 10 seconds until the AP reboots should indicate by the power LED changing color from Green to Orange.
Do you see this happening on the radio? if yes and still no response. Please send an email with device information to our support.
Have you tried connecting to it over its 169.254.0.0/16 IP address? Connect a laptop to its ethernet port, assign it an IP address in that subnet. The E400's IP will be 169.254.X.Y where X and Y are the last two bytes of the E400's MAC address.
