Hello! It seems like you are experiencing issues with your WiFi router connection even though the SIM card in your phone is working fine. Here are a few troubleshooting steps you can try to resolve the problem:
1. Check APN Settings: Make sure that the Access Point Name (APN) settings on your router are correctly configured. You may need to contact your network provider to get the correct APN settings.
2. Signal Strength: Ensure that your router is receiving a strong signal from the network. Try moving the router to a different location to see if the signal improves.
3. Reboot Router: Turn off your router, wait for a few minutes, and then turn it back on. This can sometimes help resolve connectivity issues.
4. Update Firmware: Check if there are any firmware updates available for your router. Updating the firmware may fix bugs that could be causing the connection problem.
5. Factory Reset: As a last resort, you can try performing a factory reset on your router. This will restore the router to its default settings, so make sure to note down any custom configurations before doing this.
If none of these steps solve the issue, it might be a good idea to contact your network provider for further assistance. They may be able to troubleshoot the problem from their end or provide specific settings for your router.
I hope these suggestions help you get your internet connection back up and running smoothly. Let me know if you need further assistance!
