In most cases, the issue is related to a bad WiFI signal or a slow internet connection.
Regardless of where the problem is coming from, this post will guide you through the solution.

4. Thermostat Problem
Lastly, the issue may be coming directly from your thermostat and you will have to reset its settings.

Before we proceed, we suggest trying to restart your thermostat if you haven’t done so yet.
This might be just enough to get the thermostat’s WiFi going and save you some time troubleshooting.

In case you’ve identified issues with your WiFi, in this step, we will run the overall maintenance of your setup.
Follow the steps below to detect & troubleshoot any issues in your configuration.
1. Restart Router
Unplug your router’s power adapter for 5 minutes. Once the device feels cold on touch, reconnect the power adapter and test.
2. Reconnect ALL Cables
Reconnect all cables in your configurations and make sure all of them are plugged in tightly.
3. Switch to Another WiFi Frequency
Try connecting your thermostat to a different WiFi frequency of your network.
If you don’t have one, you can create it in the router’s settings, accessed by the router’s IP.
4. Reduce Network Traffic
Reduce your network’s bandwidth usage by disconnecting unused devices and reducing any high internet usage actions, such as downloading, uploading, and high-quality streaming.
5. Try Connecting the Thermostat to Smartphone Hotspot
Turn on the hotspot on your smartphone and connect the thermostat to determine whether the issue is with your own WiFi configuration or not.
Referring to the above-described Step #3, to create a separate WiFi frequency, you must access your router’s options by opening a web browser and searching for 192.168.0.1.
On the login page, use “admin” and “password” for login credentials.
On most routers’ settings, the WiFi tab should be located in Advanced Network Settings.
From there you simply need to find the WiFi frequency and change it to 2.4GHz or 5GHz, depending on which one you’re currently using.
Lastly, restart the router to apply the changes and test if your Honeywell thermostat will now be able to connect to the network.
If the issue is still there, we recommend opening your HVAC system’s access doors for a little period of time.
Users report that this method has managed to fix WiFi issues more than once and the average time your access doors must remain open is about 5 minutes.
Open them up widely, set a timer for 5 minutes, and close them up once the timer reaches 0.
Then test if your thermostat will be able to connect to the WiFi and if it doesn’t let’s proceed with a more complex time of a reset.
Lastly, if nothing worked, a factory reset will most certainly repair the WiFi connectivity of your thermostat.
Since your thermostat is digital, follow the steps down below to execute a factory reset:
- Eject your thermostat off the wall.
- Open the battery compartment and remove the batteries.
- Place them on the opposite side for 5 seconds.
- Take them out after 5 seconds and place them correctly before closing the compartment.
Your router will now boot with reset settings!
