There are many factors that might cause your Danfoss Link CC to be off-line occasionally. Before spending the time troubleshooting your home network, you should verify that one of these more common issues aren’t causing the problem:

  1. The connection to the Internet at your home is down
  2. A power failure at home
  3. There is a problem with your Wi-Fi router

You can test this by verifying that your phone can connect to the Internet via the same Wi-Fi network.

If you are still experiencing problems – check these troubleshooting steps:

  1. Restart Wi-fi Router and/or Access point
  2. Check Wi-Fi signal strength at Danfoss Link CC – Try moving the Danfoss link CC closer to the router, if successful this may show that the signal strength is not strong enough to reach where you would like to locate your unit.

  4. Try to connect the Danfoss Link CC to a mobile hotspot using your smartphone
