If you have changed the password, you may need to perform a factory reset. Also, ensure your device is correctly connected to the router's network, either via Wi-Fi or an Ethernet cable, and try clearing your browser's cache or using a different browser.

How Do I Secure My Zyxel P-660HW-D1 Router After Login?

After successfully logging into your Zyxel P-660HW-D1 router, it's essential to take steps to secure your network.

Consider disabling Wi-Fi Protected Setup (WPS) if it's enabled, as it can be a security vulnerability. Keeping the router's firmware updated is also crucial for patching security flaws.
