Wi-Fi Troubleshooting for RFX GATEWAY

Make sure that your RFX GATEWAY has been set up with a Wi-Fi connection.

If it has not been set up with Wi-Fi yet, your RFX GATEWAY may be relying on its Bluetooth connection, which has a limited range.

It may be that your Wi-Fi network’s 2.4GHz connection isn’t strong enough in that location to remain connected to RFX GATEWAY. You can check the connection strength in the ThermoWorks app

You will then be able to view your  Wi-Fi connection strength.

1. Make sure you are entering the network’s login and password correctly. Your Network’s name is case-sensitive along with your password. Do not copy and paste the information into the login form as extra spaces may occur at the beginning or end if you do.

2. Make sure you have downloaded and installed the latest version of the ThermoWorks app.

3. Make sure that you have a Wi-Fi or Internet connection on your phone or tablet.

4. Make sure that location services are enabled on your phone or tablet and that the ThermoWorks app is authorized to use location services. (You will find location services in your phone or tablet’s settings.)

5. Make sure you are connecting to a 2.4 GHz (not 5 GHz) network. RFX GATEWAY only uses 2.4 GHz because it has a longer range than a 5 GHz network. 

A 2.4 GHz frequency network is not as negatively affected by the number of walls, floors, and other objects between the router and the device as a 5 GHz network would be. This makes a 2.4 GHz network the best option whenever a device cannot be placed close to a Wi-Fi router. Some networks “hide” their 2.4 GHz band. Contact your internet service provider (ISP) to ensure that you have a 2.4GHz option and that it’s enabled.

6. Try connecting your phone to your 2.4 GHz network prior to setting up RFX GATEWAY connection in the ThermoWorks app. This can help ensure that you are using the proper login credentials.

7. If you have a combined 2.4 & 5 GHz Wi-Fi network, try taking your RFX GATEWAY outside before setting up its Wi-Fi connection where the 5 GHz network will be weaker and the 2.4 GHz network will be stronger.

• Another solution is to give the networks different names so your phone or tablet won’t mix them up. (Example: mynetwork24 and mynetwork5)

8. Make sure you are not using a VPN (Virtual Private Network).

9. Try restarting both your RFX GATWAY and phone or tablet.

10. Try disconnecting and reconnecting your phone or tablet to your network. Afterward, begin the RFX GATEWAY setup process again.

11. Try disabling your phone’s cellular data during the setup process. You can turn it back on once it has been set up.

12. A Wi-Fi connection strength test you can easily try is to take your phone next to RFX GATEWAY and disconnect it from its cellular data signal. Then, see if your phone can connect to your local Wi-Fi 2.4GHz network correctly. If your phone has difficulties connecting (or staying connected), you will know that your local Wi-Fi network’s 2.4GHZ signal isn’t strong in that area. Try moving to a different spot or consider using a Wi-Fi booster to increase your network’s Wi-Fi range in the desired area.

13. Some people have issues connecting to a mesh network when there are multiple router devices in a mesh topology. To get your RFX GATEWAY connected, try unplugging all the routers except one. With only one router to communicate with, it should be able to connect to the 2.4 GHz portion of your network. Also with only one router online, the “walk far away” method is more effective because you don’t have to leave the 5 GHz range of multiple devices. Once the RFX GATEWAY is connected, you can turn your other routers back on.

14. Try connecting RFX GATEWAY to another network (such as a friend’s or at work) to determine if the issue is RFX GATEWAY or possibly, your network’s. If you determine that RFX GATEWAY cannot connect to any network, please let our Tech Support team know. Your RFX GATEWAY has a 2-year warranty and we are happy to help.

15. Check your router’s manufacturer’s website to see if there is a firmware update for your router. If there is, install the firmware update, reconnect your phone or tablet to your network, and then, begin the RFX GATEWAY setup process again.

16. If you are using an ad block app (such as Adguard), try disabling the app during the Wi-Fi setup process. Once the connection is established, you can re-enable the app.

Please remember that it can take up to two minutes for the probe’s temperature readings to update and appear in the ThermoWorks app after the Wi-Fi connection is established.
