Connection Test: No Link

Regions: All 

If you've received a “No Link” error during a network connection test, this indicates that Sense was unable to connect to your local Wi-Fi network.

Start by confirming that your Wi-Fi network is working properly. Test this usinga different device. We recommend you use your laptop to confirm that it can connect to your Wi-Fi network. 

1. Open a browser window and run www.speedtest.net , or go to YouTube and ensure that a video runs.
2. If you must use your phone, make sure your phone’s browser is not accessing cellular data. You may need to disable cellular data options at more than one level: in the Settings for the entire phone and in the Settings for the particular app you’re testing (browser or YouTube). Now confirm that the app opens and runs on another device, which means it is accessing the Wi-Fi channel you want Sense to access. If not, then the issue is definitely something you’ll have to resolve before Sense will be able to connect. 

Once you are certain the Wi-Fi network is working properly, there are two additional issues that may be contributing to Sense’s failure to link.

1. The network is rejecting the connection
2. The network times out before making the connection

Your network could reject Sense’s request to connect. If this is the case, there are several causes to look for:

• The network credentials have been entered incorrectly.
• A firewall or other security mechanism is blocking the connection.
• Your network is trying to connect Sense using a 5GHz bandwidth, but Sense is designed to connect only via a 2.4GHz bandwidth that allows a larger range.
• The network encryption is WEP instead of our recommended WPA2.
• In rare cases, a non-standard router may be incompatible with Sense. 

Your network could have timed out when trying to connect for one these two possible reasons: 

• The router is too far away from Sense. Ensure the router is no more than 15-20’ from the Sense Monitor (also that it is no closer than 3-5’). Move the Wi-Fi router or set up a new access point using a Wi-Fi extender. This should enable your Sense Monitor to associate with the network. 
• The antenna needs to be re-oriented. Move it around as you might do with a TV or radio antenna. Tip: antennas broadcast and receive best via their sides, not their end.
