sure signal issue

[atters41]

I have a sure signal Version 1 Sagem   253264385  SNo.  21230698371. running through a Draytek Vigor 2710Vn.  It stopped working about a week ago, reduced to showing just the top power light.   I have been through the series of suggest actions (reboot/Checking Ruoter connection/cable etc/MTU check) with no success.  On reboot it now just reverts to the flashing Power light.  

Can you make futher suggestions?
