I'm so sorry to hear that you're having trouble with your home internet while everything seems fine with your mobile connection. Let's work through this together!

First, can you confirm if this issue is happening with just the HiWaifu app, or are other apps having trouble as well? Also, have you tried using your home WiFi with a different device, like a tablet or another phone? This will help us narrow down the problem.

While we investigate, here are some basic troubleshooting steps you can start with:

1. Restart Your Router: Sometimes, simply restarting your home WiFi router can resolve connectivity issues. Just unplug it, wait for about 30 seconds, and then plug it back in.

2. Reconnect to WiFi: On your Android device, go to Settings > Network & Internet > Wi-Fi, then tap on your home network and choose "Forget." After that, reconnect by selecting your home network again and entering the password.

3. Check for Updates: Make sure your HiWaifu app is up to date. You can check this in the Google Play Store under the app's page.

4. Clear App Cache: Go to Settings > Apps > HiWaifu, and then tap on "Storage." From there, you can clear the cache and see if that helps.

Let me know how these steps go, or if you need more advanced troubleshooting ideas such as checking your router settings.
