Went through the rounds - checked the phones, no stuck keys - Went back to the box - checked all wires. For some reason - the ethernet cable is either old or loose, because a slight movement, the network light goes off. then comes back online. < - replaced it with a brand new patch cord. - No more lights getting stuck. I am not sure if this solved the issue - but it is holding steady and free of trouble.. Thank you for looking into it everyone!
