Certain devices struggle to detect Wi-Fi networks because they may not support the same frequency band (like 5 GHz) or the network’s broadcast settings might be hidden. Try moving your device closer to the router to see if that helps detect the signal. Alternatively, double-check your router’s configuration, ensure you’re using a frequency band that your device can handle and make sure your network name (SSID) isn’t set to hidden mode. A quick router reboot or firmware update can also help your network pop right back up.
