Before making any changes to your router configuration, you need to ensure a stable connection between your device and the router. It's best to use a wired connection via LAN cable, as this will prevent connection interruptions when changing wireless network settings. If this isn't possible, make sure your smartphone or laptop is connected to the current Wi-Fi network, even if it's not currently secured.

Make sure your device is configured to obtain an IP address automatically. In most cases, operating systems do this automatically, but in rare cases, a static IP address can prevent access to the router's web interface.
Login to the router's web interface
Open any browser on the connected device. Enter the router's IP address in the address bar. For the vast majority of models TP-Link, including the series WR740N, the standard address is 192.168.0.1 or 192.168.1.1If none of these work, check the gateway address in your computer's network settings.
