There could be various reasons why Planet Fitness's WiFi isn't working. It could be due to technical problems such as network outage, configuration issues, or router malfunction. It could also be because of interference from other electronic devices or a weak signal in the specific location where you are trying to connect.
To diagnose and fix the problem, here are a few things you can do:
1. Check your device's settings to ensure that the WiFi is turned on and that you have the correct password.
2. Verify that other people are experiencing the same issue. If nobody else seems to be having a problem, the problem may be with your device.
3. Try moving closer to the router or access point. Sometimes, the signal strength may be too weak to pick up the WiFi signal from a distance.
4. If the signal strength is good but you still can't connect, try restarting your device or resetting the router.
5. Lastly, contact the Planet Fitness's technical support team or IT department to see if they can help you troubleshoot the issue, or if there is a wider problem causing the WiFi to not function correctly.
