Step 1: Check the DNS settings

In most cases, the system server fails to connect due to incorrect DNS settings. First, go to the settings and check them to ensure they are correct. If the settings are not correct, reset them to their original state. Reset them according to the desired state following the manufacturer’s manual guide. If you are experiencing any issue with knowing the DNS settings, use the google search engine to get the correct details.

Step 2: Inspect the internet connection

Sometimes, your router may be faulty and keep disconnecting your carrier infinitely, or the internet connection may fail to connect to the server. First, check your router and see if it is in a good state. If not, fix it first and try connecting the server again.

When it comes to the internet connection, the best way to see if it is functioning is by carrying out a speed test to know the frequency at which it is running. Try making some adjustments. Also, check if your subscription has expired and renew it to get bundles and reconnect your system again. But if the issue persists, contact the ISP.

Enabling the legacy support device is one of the common ways of troubleshooting the issue of carrier infinity cot connected. Your system only supports one model that is commonly known as the 802.11band if the option is off, you won’t be able to join the server. Therefore, go to the “enable legacy device support” and enable it. Test the system server to see if it is connecting and if it fails, proceed to the next step.

Also, check if your device is connected to the internet. Sometimes, you may find your device is not connecting to the internet correctly. Try changing the settings and rebooting your system. Establish the connection and see if it is accurate. But if the issue is not with the device’s internet connectivity, seek help from an electrician, and the problem persists. Consider replacing the device with a new one.

When replacing the device, ensure you buy a device functioning correctly and is from a genuine retailer. Also, ensure it is of high quality and is in the latest version to get a device with advanced features. Finally, ensure the device satisfies your taste.

Step 5: Check the setting of your device server

Steps on how to fix a carrier infinity thermostat that isn’t working

Once your carrier infinity thermostat fails to function, you may experience a lot of stress since you cannot control the temperatures of different rooms. In this case, it is essential to try solving the issue on your own rather than seeking help from an electrician. Some tips are simple, and they include the following;

i. Check the system switch

In most cases, the reason why your device is not functioning is that it is off. First, turn on the device and verify that there is a sufficient power supply from the source. Also, check the circuit breakers if they are on and turn them on if they are off. Mostly, the breakers get tripped, and they accidentally switch off.

ii. Check the battery state

If your carrier infinity thermostat uses a battery, check to see if it is complete. At times, your battery may become flat or dead, and the only way to fix such an issue is by replacing it with a new one that suits the device and testing it to see if the issue persists. But, if the battery has no power, first charge it until complete and try using it to see if the problem continues.
