I set up successfully yesterday. everything worked well even I left home and still can watch the house. Then I unplug the power cable to move the camera to other place I wanted. Then it start problem. My TP-Link router is working well. Iphone connected the wifi. Ethernet cable bind the router with camera again. Tried push and hold WPS 5s, it didn't work. What should I do to set up it successfully. It's flashing red whenever power is on
