How long did you let them run? This could be a result of a few things. You could be impatient and haven't given them the possible 15 minutes they need to get restarted and connected to a pool. You could have entered your pool information wrong so it is stuck in a soft resetting loop. Your network could be having an issue and the miners aren't getting online.
So what I would do is connect something to one of those ethernet cables and confirm the internet is working. Triple check your pool information to make sure it is correct. Then reset them and go have lunch. Come back in a half hour and check on them.
