As a smartwatch, the Fitbit device will need an internet connection to be able to maximize the use of all of tis features. This device connects to a Wi-Fi network for internet connectivity. Sometimes though, you might experience problems connecting to the network. Here’s what you need to do to fix this problem.

Solution 1: Check the Wi-Fi network

Check the Wi-Fi network

The first thing you will want to do in this case is to make sure that other devices can connect to the Wi-Fi network and that it is working properly. If necessary you should connect another device to the network, such as your smartphone, then check if it can access the internet without any issues.

Take note that the Fitbit smartwatch can connect to open, WEP, WPA personal, and WPA2 personal Wi-Fi networks. It will not connect to 5GHz, WPA enterprise, or public Wi-Fi networks that require more than a password to connect—for example, logins, subscriptions, or profiles. If you see fields for a username or domain when connecting to the Wi-Fi network on a computer, the network isn’t supported.

If you have a hidden Wi-Fi network then you will need to add this network manually using the Fitbit app on the connected smartphone.

Make sure that the router is within range of the Fitbit smartwatch.

You can also try connecting your Fitbit watch to the personal hotspot of your mobile device just to check if its Wi-Fi connectivity is working.
