I just flashed my EX2700 with openWRT. But now neither the WiFi nor the wires connector appears to work. the Power LED shows constant amber.
If I press and hold the reset button while powering the device on the power LED 1st flashed amber and then after maybe 6 flashes, it starts flashing green. It never turns constant green.
What is the standard method to do the "first contact" to configure the newly flashed device in the case of this range extender.
A first step is to read the page with the device details.
I hope you flashed from the stock firmware with the correct factory image and not the sysupgrade.
