I was using the latest Merlin firmware 380.60 for AC87U and for a couple a days it worked but I don't know why its not working anymore.The router is in rescue mode the power LED is blinking slowly I've tried to restore with there utility the latest firmware but i get invalid IP address on there application .My computer says that the network cable is unplugged its not communicating with the router.I've alocated a static IP address like in there tutorial but there is no error on there picture that cable is unplugged I can't upload the firmware.
