Turn the modem power OFF before disconnecting - that will ensure it is seen as a managed disconnect rather than a loss of sync.
Then disconnect everything and remove the front plate to check there are no wires connected to it. Following that, carefully remove te next level and check the connections there - you should ONLY see two connections to the incoming screw terminals and nothing else. Carefully replace and refit the faceplate.

If you are unsure of anything, take pictures, host on Photobucket, Flikr, ... and provide a link here.
