Ok started from scratch and removed all cables from modem and with power off reinstalled coaxial (I think it may have been a bit cross threaded as it was a bear to unscrew) and then power as all the lights started to come back on I reinstalled network cables, and it is now working. The issue seems to have been the coaxial was finger tight but cross threaded, thanks for the assitance.
