RBR50 Flashing white light

[GeorgeMansell]

Last night my wifi went down and upon further inspection the router is flashing a white light. I have tried factory resetting / tftp flash to no avail. Any suggestions? 

I am unsure as to why it would have done this in the first place as I was not messing with it, it just went down randomly.

So pressing the reset button for 15 seconds then release and connecting a wired PC to the back of the RBR doesn't gain access to 192.168.1.1 after the top ring LED pulsates WHITE?

No, this doesnt work, it just stays flashing white.

And that with the RBR disconnected from the ISP modem as well?
