Reasons Fitbit Aria Won’t Connect to Wi-Fi

The Fitbit Aria scale doesn’t support 5GHz, and that’s the reason it won’t connect to Wi-Fi. Part of the issue is also your device’s connection. If your laptop is connected to 5GHz wireless, it’s also a part of the issue. Other reasons include:

  • Wi-Fi obstacles: There are tons of things that can interfere with the wireless signal. Solid objects, mirrors, large bodies of water, metal objects, and microwaves are the most common household items that can interfere with the signal.
  • Heavy network traffic: One of the most common reasons Wi-Fi connectivity issues happen is heavy traffic on the network. This might be the reason your Fitbit Aria won’t connect to Wi-Fi.
  • Fitbit app issues: Another thing that can cause the device not to connect to Wi-Fi is the app itself. If there was a power outage when an update was in progress, or the cache is simply overloaded, the app might not work properly, and it might not connect to Wi-Fi.

Fitbit Aria Won’t Connect to Wi-Fi Fixes

If you set up your Fitbit Aria scale correctly, and it still isn’t connecting to Wi-Fi, you can refer to the reasons it’s not working and try one of the following fixes. Hopefully, one of them will resolve the issue and sync your scale.

Change Preferred Band

The first thing you need to try when trying to sync your Fitbit Aria scale is to change the preferred band to 2.4 GHz on your device. So, if you’re using a Windows 10 device to connect your Fitbit to Wi-Fi, you need to go to the Search box next to the Windows menu button.

Once there, type Device Manager, and click on the first result that appears. Then, go to the Network Adapters section and expand it. Next, right-click on your wireless adapter, and click on Properties.

Go to the Advanced tab, and click on Preferred Band. Once there, you need to click on the drop-down menu and select Prefer 2.4 GHz band. Finally, click OK and you’re done, you shouldn’t have any issues when connecting.

Disable 5GHz Band

Disable 5GHz network

If you’ve switched the preferred band to be 2.4 GHz, and it’s still not connecting, you might need to disable the 5 GHz band completely. To do this, you need to log into your router settings page. Usually, the thing you need to type into the address bar of your browser is

Hit Enter, and use your credentials to log in. Next, locate the Wireless tab on your router’s settings page. Most routers have the 2.4 GHz and 5 GHz separate sections, there are checkboxes next to them, just uncheck the 5 GHz one. Click Apply, and that’s it.

Router Reboot

In the situation where the previous two solutions don’t work, we need to perform regular troubleshooting steps. The first one is to reboot the router to see if the problem gets resolved. Rebooting the router refreshes the connection.

Router Repositioning

When rebooting doesn’t work, there might be something interfering with the Wi-Fi signal that’s trying to reach your device or the Fitbit Aria scale. So, you need to reposition the router. Try putting it in a location where it’s not mostly surrounded by walls. Ergo, avoid corners.

Also, avoid aquariums, avoid mirrors, avoid the kitchen, but also try putting it in a higher position in a central area in your home. Once you reposition the router, try connecting the scale to Wi-Fi using the setup procedure.

Scale Repositioning

Well, you can only assume that if the router repositioning didn’t work, you need to reposition the scale. Try putting it closer to the router and seeing if it’s going to connect. If not, continue with the following troubleshooting steps.

Remove Unwanted WI-FI Leeches

A good way to get rid of most Wi-Fi connectivity issues is to simply change the name and password. Changing the SSID and the password of your wireless network removes all the unwanted connected devices.

Log into your router’s settings, go to the wireless settings section and change the SSID and password parameters. Once you do that, you need to click Apply. You’ll be temporarily disconnected, simply reconnect and see if your Fitbit Aria works.

Upgrade Fitbit Aria

Fitbit Aria to Fitbit Aria 2

If none of the previous solutions work, you might need to upgrade your Aria to an Aria 2 scale. Of course, this is completely up to you, and you might want to call customer service if you’re experiencing a lot of issues regarding the scale.


There you have it, the reasons and solutions to when your Fitbit Aria won’t connect to Wi-Fi. If nothing works, then we suggest changing the brand. Hopefully, it won’t come to this and you get the issue resolved.

However, try going through all the troubleshooting steps, and contact your ISP to see if the issue is not with them. It’s usually related to 5 GHz and 2.4 GHz Wi-Fi. Disabling the 5 GHz band should work fine.
