Honeywell Wifi Thermostat Connection Failure
Before fixing, you should know the factors that lead to Thermostat Connection Failure. After that, you can determine the solutions. Some problems require professional handling if, as the owner, you do not know how to perform the complicated steps.
1. Router and modem
You may have a router or modem as the source of the internet connection. The thermostat will scan and see the WiFi name from the router. Some people separate this one from the modem. The connection failure happens because the device cannot connect to your router.
It can happen after you change the WiFi name, setting, password, and anything that compromises the connection. Moreover, you may modify the parameter, and the thermostat does not recognize it anymore.
If this one is not the problem, the router must be broken or defective. Therefore, you will face Honeywell WiFi thermostat internet connection loss.
2. Internet connection
The next source of the problem is the internet connection. In general, this factor is not your fault because the internet is from an ISP. The network might be down, and there is no internet at all.
You can check directly on the thermostat and see the WiFi icon has a particular sign that indicates no internet.
3. Wireless adaptor is broken
Honeywell’s thermostat uses a wireless adaptor as a component for this connection. It is similar to smartphones, laptops, and other devices that can connect via WiFi. This component is rare to be failed unless it is completely broken.
You should check the router and make sure there is no issue. The last thing you should check is the adaptor in this thermostat.
Thermostat Connection Failure happens when your room has too many devices and crowd frequency. Smartphones, laptops, televisions, and more devices utilize WiFi from a single access point. In general, a router can handle even ten connections simultaneously.
However, your thermostat might be the last to connect to the competition.
Interference also comes from electronic appliances, such as refrigerators, microwaves, televisions, etc. They have a magnetic component that can affect the adaptor. It happens in the room where each appliance and device is located closely, even next to each other, without a gap.
How to Connect Honeywell Thermostat to Wifi
The following section will explain how to fix the Honeywell Thermostat Connection Failure. You already know the factors that lead to this situation. Several solutions are available, and you can choose and implement them properly.
- If the router is the main problem, you can restart it. After that, go to the thermostat and find the WiFi setting. Forget the existing network and clean all parameters. Then, scan it again and see the access point. Connect manually and set it into an automatic connection next time. Next, enter the parameters, and then the connection is made.
- If the problem is in the internet connection, you wait until it comes back or call the internet provider. Alternatively, you can find other sources, such as mobile broadband. This one is a good step to fix Honeywell’s thermostat connection problems.
