You might need to know How to Connect Honeywell Wireless Thermostat to Router for the first time, or to change to a new WiFi network. Perhaps you moved it, and the internet connection it worked with before is now out of range. So in this post, we cover the Connect Honeywell Thermostat to Internet procedure.

Perhaps you have changed the name of your network. Or perhaps you changed your network router and didn’t set your new router’s network name and password exactly the same as were the ones on the old router set. Or, you may want to connect the t-stat to a new access point in your home. For all of these cases, you can reconnect a Honeywell thermostat to the internet by following the how-to directions below.

How to Connect Honeywell Wireless Thermostat to Router: Step by Step

For sure, Honeywell really improved the internet setup routine for this smart t-stat. Indeed, you no longer must reconnect to it via a tablet or phone to update network settings. Instead, you can now set up the entire link via the touchscreen menu system on many models. Here’s how.

1. Enter Internet Setup Mode

First of all, switch from normal to WiFi setup as follows. Press the Menu button at the top right of the Home screen, as shown above.

Then, scroll with the arrow keys at right, through the main menu. Stop scrolling when you see the WiFi Setup button, as shown next.

Next, press the WiFi Setup button, circled in red in the above pic. The setup screen then displays, as shown next. Note that we have blanked the t-stat MAC address and CRC values, to preserve its anonymity. Also note that normally, this screen shows the status of the connected network. But here, the OurHouse1 network is not in range (no signal). So we’re going to discard the OurHouse1 info, and replace it with an in-range network in the following steps.

2. Disconnect the Thermostat from its Current WiFi Network

Skip this step if connecting the thermostat for the first time.

Then press the Disconnect from Network button. The WiFi Network Disconnect Confirmation screen appears, as follows.

Press the green Yes button.

After a pause, the system lets you know that it disconnected from the old network, as shown next.

Then, press the green OK button in the lower right corner of the screen. This takes you back to the main menu, as shown next.

3. Find the WiFi Setup Button

From there then, use the UP and DOWN arrow keys to scroll through the menu to the Wi-Fi Setup button.

4. Tap the WiFi Setup Button

Then, press the red-circled WiFi Setup button. When no network information resides in the t-stat, pressing Wi-Fi Setup starts a scan for in-range networks.

Then, a brief message displays, telling that the network scan is in progress.

Then, most Honeywell smart thermostats list the close by networks they find, on their Select Wi-Fi Network screen, as follows:

The -Select WiFi Network- screen.

5. Find Your Desired Network

Then, tap the network in the list to which you wish to connect the smart t-stat. So in our case, we’re connecting to the 937T681J4059H_2G wireless network. The WiFi Password Entry screen then appears, as follows.

Next, use the displayed virtual keyboard to enter your password. Then, to enter numbers and punctuation characters, press the ?123 key. Why? Because this switches the keyboard to number entry mode.

The password characters appear as you type them. So do this when no one is looking.

7. Connect to the Network you Chose

Once you enter the password characters, press the green Done button.

The thermostat then tries to connect to the chosen internet network. While reconnecting, it displays the following screen.

The -Connecting To WiFi Network- screen.

Then, if no errors happen, the system reconnects to the internet source you picked.

Then it displays the following screen. It shows the name of the wireless network that the t-stat now connects with.

8. Register Your Thermostat Online for Remote Access

Next, press the green OK button.

Then, the Register Online for Remote Access screen displays, as shown next.

Now perhaps you already registered your t-stat. If so, then you need not register it again, so long as you have not unregistered it. Note that reconnecting to a new network does not unregister a Honeywell thermostat.

The -Register Online for Remote Access- screen.

Then, press the green Done button.

The system then returns to the Wi-Fi Setup screen. But this time, the connected network settings appear, as shown in the next shot.
