Cannot connect to EX6200

Hi, I've had this hardware for over 6 months now, and for the majority of the time it has been fine. In the last month or so I have noticed that the EX6200 will drop its connection every few days and I have to go through the setup again. Well the last time it dropped its connection I have been unable to load the setup. I have tried all methods listed and I've been unable to connect to www.mywifiext.net.

The lights on the device are going crazy; all 9 lights will light up green, then the 1-5 lights will drop then reappear after a second, then all lights will drop and just the 2.4, 5 & link lights will illuminate amber. Then those 3 will drop and all 9 come back on green again. This cycle takes about 5 seconds and just repeats. The reset button does nothing, the WPS button does nothing. I've turned the power off and on multiple times and tried multiple devices. 

I cant connect to update the firmware using the instructions provided. It seems I can't do anything with it.

Any help greatly appreciated thanks.
