We're glad to know that the modem is now working, In the event that it starts to acting up again. Please let us know. You may also respond to the Private Message that one of my colleagues sent you.
Thanks for follow up. As a last resort I unplugged and opened up the router (3 screws and prize open). Jiggled the reset button and plugged in to test. Modem now works so far so will wait and see.
