Recently, some users reported having trouble connecting their Cor thermostat to their Wi-Fi network.
So if your Cor thermostat is experiencing internet issues, you are not alone.
Just like any other smart gadgets, problems can happen with this smart thermostat.
A stable Wi-Fi connection is important for your Cor thermostat to connect to the Cor mobile app and enable you to manage your HVAC devices remotely, access all kinds of features, and get notifications.
This article discusses the major reasons your Cor thermostat may fail to connect to the Wi-Fi, and you can troubleshoot the connectivity issues and get your thermostat to work properly.
Why is My Cor Thermostat Not Connecting to Wi-Fi?
Reason 1: Weak Wi-Fi signals
The most common reason your Cor thermostat may not be able to find your Wi-Fi network is poor signal intensity.
In certain cases, you can blame your internet provider for unreliable internet connection in your area.
Poor internet service in your area may weaken the Wi-Fi signal in your home. Sometimes, you might experience Wi-Fi problems, as some internet providers tend to slow down users’ connections during peak hours.
Sometimes, your internet provider might also be dealing with network overcrowding in your neighborhood. This may happen as your internet provider could have increased its customer base without upgrading the equipment in the area.
A weaker signal in some areas of your home indicates that your house might be too big for your router.
How to fix: Troubleshoot poor internet connection
- Contact customer support of your internet provider and ask them about Wi-Fi connectivity issues you are experiencing.
- Alternatively, you can upgrade your internet plan to try to improve the connection throughout your home.
- Buy a Wi-Fi range extender: If your Cor thermostat is too far away from the router, you can buy a wireless signal extender to boost the signal strength. The extender will increase the Wi-Fi coverage of your router and help you get a stronger signal in remote areas of your house.
- Alternatively, you can buy a mesh system. It is a bit expensive but is a more effective solution to your coverage issues.
Reason 2: Issues with Wi-Fi routers
If your Wi-Fi router is configured incorrectly or has an internal fault, then your Cor thermostat won’t be able to connect.
Sometimes, the location of your Wi-Fi router can affect the connectivity of your thermostat.
Also, if your thermostat is too far away from the router or if there are physical barriers between the two, such as furniture or walls, the signal strength might be weak.
Outdated firmware is also another reason your router may be faulty. Today, most routers can perform automatic updates. But if your router is unable to conduct such updates, then it means it is experiencing problems.
How to fix: Reset the router
- It’s important that you place your router properly to ensure the optimal connection.
- You should always place the router at the center of the house.
- Walls and floors are closed to the router. They will, therefore, make the signals bounce off and become weaker. The same applies to furniture and large appliances. You should, therefore, never place your router too close to them.
- Restart your router to help address different issues affecting its reliability. Follow the router manual book to understand how to restart the router.
- If that doesn’t address the Wi-Fi problem, conduct a factory reset on the router. Also, follow the router manual book to perform the factory reset.
- As said earlier, outdated firmware can affect the performance of your router. So, you’ll need to update your router software. To do so, go to the log-in to the router’s configuration page and do the update. Your router will then begin updating. You should give the device about 10 minutes before using it again.
Reason 3: Connection interference with your Cor thermostat
Wi-Fi connection problems also happen because of interferences from other devices in the shared network.
One of the common internet connection issues that you are likely to encounter using your Cor thermostat is due to the extreme interference caused by other devices in your home.
If you’ve connected several devices to the 2.4GHz band of your Wi-Fi router or even the router that works on a 5GHz band, this will interfere with the internet speed.
Cor thermostats only support 2.4GHz frequency bands.
Gadgets operating on a 2.4 GHz frequency, such as Bluetooth devices, microwaves, smartphones, smart security cameras, baby monitors, and others, can disrupt your thermostat signal.
These smart gadgets and your thermostat operate on the same frequency band.
As a result, your thermostat might have problems connecting with your Wi-Fi if there are too many devices on the same frequency.
How to fix: Troubleshoot radio frequency interference issues
- Ensure your Cor thermostat is paired to the correct frequency to connect to your network successfully. This thermostat works on the 2.4 GHz only. It does not support 5GHz networks or connecting to peer-to-peer (or ad-hoc) Wi-Fi networks.
- Radio frequency interference is another issue causing connectivity problems. If the signal strength drops below 36, try switching off these optional devices.
- Also, try disconnecting most of your unnecessary smart devices. This will help you reduce the traffic to your Wi-Fi router and ensure you don’t exceed the maximum device limit.
- After that, check the signal strength again and assess any improvements.
Reason 4: Outdated Software
If your Cor thermostat is not using the most recent app update, it will encounter trouble locating Wi-Fi.
An outdated firmware can cause compatibility issues. Furthermore, connection issues will always arise when the thermostat applications and firmware become obsolete.
Cor thermostats will update themselves automatically, but sometimes, it may not notify you of any recent updates.
So, you need to periodically assess your thermostat to ensure that all the required firmware updates are installed effectively.
How to fix: Update software
- Check if there are any software updates available for your Cor thermostat.
- Updating your thermostat’s system software can help fix connectivity problems and enhance its performance.
- Use the manual book to follow how to update your Cor thermostat’s system software.
Reason 5: Power outage / electrical issues
Electrical problems and power outage is other issues that can cause your Cor thermostat to lose its Wi-Fi connection.
Your Wi-Fi network will automatically disconnect whenever there’s an outage.
If there’s a power outage in your area, don’t get too worried about the thermostat Wi-Fi not functioning. The Wi-Fi will automatically reconnect when the power is restored.
On the other hand, whenever the battery voltage is low, your Cor thermostat will enter into a power-saving mode and disconnect from the Wi-Fi.
How to fix: Diagnose power issues
- The only way to address the outage issue is to wait for the power to return. In most cases, it won’t take too long.
- Check the battery voltage on your thermostat.
- If the voltage is lower than 3.6V, it means the batteries are low and should be recharged.
- Also, check the current battery levels.
- If it’s too low, the indication status will read “Very Low.” That means you’ll need to replace the batteries.
- After you’ve recharged the thermostat overnight or for several hours, reinstall the device and see if the power issue is resolved.
- Recheck the battery levels.
Reason 6: Contact customer support
If all the above solutions have not resolved the Wi-Fi connectivity problems, the final thing to do is to contact customer support managing Cor thermostat services, and they’ll inform you what to do.
Perhaps there is a hardware problem with either your Cor thermostat or the router.
How to fix: Reach out to technicians
- Contact customer support to help you diagnose and fix the connection issue facing your Cor thermostat.
- The Cor thermostat comes with a 1 or 2 year warranty and other related services. So the company can address the problem for you.
- If your Cor thermostat has no problem, then it means your router is the culprit.
- You’ll, therefore, have to contact your internet provider to come and assess your router.
My Final Thoughts
Cor thermostats are more efficient and much easier to use.
The Cor thermostat connects to your smartphone via Wi-Fi, and you can control it from wherever you are. It is the engine of your HVAC system that keeps the climate comfortable in your home.
However, whenever the thermostat Wi-Fi stops working, it can be very inconvenient for you.
It’s good that you’ve learned all the steps you can take when your Cor thermostat can’t connect to Wi-Fi.
