Hi! I understand you want to set up a new modem password using the LazyFit app on your Mac running OS X 10.15.7. Before we jump in, could you please clarify if you're trying to change the Wi-Fi password of your modem/router or the admin password you use to access the modem’s settings? Also, are you currently connected to the modem's network?

Knowing this will help me guide you correctly through the process. Let me know!

I got a new modem and your software doesn’t recognize it. Yes I am currently using the new modem.

Thanks for the extra details! Since you mentioned you have a new modem and the LazyFit app doesn’t recognize it, this can sometimes happen if the app's network detection needs a refresh or the modem settings differ from what the app expects.

Here's how we can try to resolve this step-by-step:

1. Restart the LazyFit App
- Quit the LazyFit app completely on your Mac. You can do this by right-clicking the app icon in the Dock and selecting "Quit" or pressing Command + Q.
- Then, reopen the app and see if it now detects the new modem.

2. Restart Your Modem
- Power off the modem, wait about 30 seconds, and power it back on. This can refresh the network connection.

3. Check Network Connection
- Ensure your Mac is connected to the modem’s Wi-Fi or via Ethernet. Sometimes the app won't detect the modem if you are on a different network.

4. Update the LazyFit App
- Double-check if there is an update available for the LazyFit app through the App Store. An update might include support for newer modems.

5. Reset Network Preferences (If comfortable)
- On your Mac, you can try removing and re-adding the Wi-Fi connection to ensure network profiles are refreshed.

If after these steps the problem persists, the app might not yet fully support your specific modem model. There is a recent video guide addressing LazyFit app issues that could be helpful: How To Fix LazyFit App Not Working (2025) 1.

Would you like me to walk you through any of these steps in detail? Or have you already tried some of them?
