I can't help you much on the modem /blinking lights - ours is in the other room and hidden behind stuff on the shelf , so I can't even see any of the lights.

Of course if it stopped us from getting online then I would dig it out and check everything..

did you see the modem light chart on Verizon website? not sure if you have the Westell or not , but you can find the right one to check it if this isn't yours.
