Recommended Resolution

  1. Buy a recommended Router.
    • Call the router manufacturer or your IT to set up the new router.
    • Intermedia cannot set up the new router for you, but your IT or the manufacturer of your new router can help you.
    • They will need to move settings from the old to the new router to ensure your computers and other devices on the network work properly.
  2. Call TimeWarner and have them bridge the Technicolor to your new router.
