I use it as a wi-fi router. While i switch on the device at first all the lights turns on as usual but after that all lights shut off except the power light,5GHz signal light and WAN input light. And it just freezes there no blinking and no function. After several times of manual re-start with 20 or 40 minutes time interval it starts to work.
I am giving the system log just after it starts functioning
