What does B-INIT-RNG failure mean and it says retries exceeded and my modem restarted randomly.?
A Modem 'dials' and it should only do it a certain number of times (redial) before it gives up. Hence 'retires exceeded'. So it wasn't getting a response from your ISP. Typically A) You didn't pay your Bill (did you?) B) Service issue (ISP office it tries to call is down) C) there is a issue with your connection from the modem 'outside' (i.e. did a mouse in the wall chew through the wire?).
ALL these answers all still require you to CALL your ISP and ASK for SUPPORT. That is what your paying for, and no forum can resolve ISP issues ever for you.
