To change wifi on Fitbit Aria, you must put the scale into setup mode and use a web browser on your phone, tablet, or computer, the original Aria does not use the Fitbit app for this. The scale requires a 2.4 GHz network with WEP, WPA, or WPA2 personal security and automatic DHCP; static IP setups are not supported.
How to change wifi on Fitbit Aria: what you need
Before starting, confirm your home network meets the Aria’s requirements: it must broadcast on 2.4 GHz, use WEP, WPA, or WPA2 personal security, and have DHCP enabled (static IP is not supported). Unlike newer Fitbit devices, the original Aria’s setup is done entirely in a web browser at the scale setup page, not through the Fitbit app. The official help page says the setup can be done from a computer, phone, or tablet with a web browser. To start setup, open the scale setup page in a web browser and click 'Get Started'.
Put your Fitbit Aria into setup mode
- Remove one battery from the scale and wait 10 seconds.
- Reinsert the battery. The scale will power on and show its current Wi‑Fi status.
- When the display reads Wi‑Fi is (your network name) followed by Tap to change, press firmly and briefly on the two corners farthest from the display (the lower two corners) until the screen shows Setup active.
If the screen goes blank or shows a weight reading instead, remove the battery again, wait 10 seconds, and repeat the process.
Connect to the scale’s temporary Wi‑Fi network
- On your phone, tablet, or computer, open the list of available Wi‑Fi networks. You will see a network named Aria followed by six characters, this is the scale’s temporary network. The scale's temporary Wi‑Fi network name appears as 'Aria' followed by 6 characters.
- Switch to that network. No password is needed.
- Return to the browser where you have the scale setup page open and tap I’m Connected.
The browser will then scan for nearby wireless networks and display them.
Select your new home Wi‑Fi network
- From the list of available networks shown in the browser, choose your new home Wi‑Fi network.
- If your network does not appear, tap Refresh Networks to scan again.
- If it still does not appear, tap Join Other Network and manually enter the network name (SSID) and password.
- Enter a name for the scale and your initials when prompted, then complete the setup.
The scale will now connect to your new home network and begin syncing data.
Troubleshooting Wi‑Fi problems on Fitbit Aria
If the scale shows Tap to change during setup, press firmly on the two corners farthest from the display to enter Setup active mode. If the screen goes blank or shows measurement information instead of setup status, remove and reinsert a battery and try again. If your home network cannot be found during the browser scan, use Refresh Networks or Join Other Network to enter the details manually. If the network cannot be found during setup, use 'Refresh Networks' or 'Join Other Network' in the browser flow. If your router uses a static IP configuration or does not support the required security types (WEP, WPA, WPA2 personal), the scale will not connect.
Frequently Asked Questions
Do I use the Fitbit app to change the Wi‑Fi on my original Aria?
No. The original Aria does not have an in-app Wi‑Fi settings menu. All Wi‑Fi changes are done through a web browser at the scale setup page, following the steps to put the scale into setup mode and connect to its temporary network.
What happens if I change my router or internet provider?
You must repeat the full setup process: put the scale into setup mode, connect to its temporary Aria network, and select the new home network in the browser flow. The scale will not automatically detect a new router or network name.
Why does my scale still show the old network name after I changed my password?
The Aria stores the previous network credentials.
Can I use a 5 GHz Wi‑Fi network with my original Aria?
No. The original Aria only supports 2.4 GHz Wi‑Fi. If your router broadcasts both bands, ensure your phone or tablet is connected to the 2.4 GHz network during setup, and select the 2.4 GHz network name in the browser.
How do I know if my router’s settings are compatible with the Aria?
The Aria requires a router that uses DHCP (automatic IP assignment), not static IP. It also needs WEP, WPA, or WPA2 personal security. If your router uses enterprise-level security or a static IP configuration, the scale will not connect. The pages retrieved do not list a required app version, iOS version, or Android version for this Aria Wi‑Fi change process.
