Sometimes, router settings can be a bit finicky. Here are a few additional steps you might try:
- Log in to your router settings through a web browser on a device that's connected to the Wi-Fi. Ensure that the router's firmware is updated and that there are no specific settings indicating devices are "away" or restrictions based on location.
- Sometimes, resetting network settings on the iPhone can help. Go to Settings > General > Transfer & Reset Reset > Reset Network Settings. This will erase saved Wi-Fi networks, so you'll need to re-enter passwords.
- Change the name of your Wi-Fi network (SSID) slightly. This can prompt your iPhone to recognize it as a new network and might resolve the issue.
- Assign a static IP address to your iPhone. Sometimes, dynamic IP settings can cause connectivity issues. Go to Settings > Wi-Fi > (tap on your network) > Configure IP > Manual, and then set up a static IP.
- If the issue persists, it might be a good idea to reach out to your Internet Service Provider (ISP) for further assistance or the manufacturer's support for your router.
- Consider using a different Wi-Fi network or setting up a personal hotspot temporarily to see if the issue is specific to your home network or your iPhone.
Always ensure that your router firmware is updated to the latest version. If none of these steps solve the issue, contacting Apple support might be the best next step, especially if it seems to be an iPhone-specific problem.
