My modem is making this awful high pitched sound. I have unplugged it into several different outlets and no luck. Help!!! This is super disappointing for a relatively new modem.

  1. unplug it. 
  2. check to see if you have a different power adapter the matches the current one. Usually its from the power supply. 
  3. is it still in warranty?
