Securing your 3Com 3CRWDR101B-75 (WL-552) router after logging into its admin panel is crucial for protecting your network from unauthorized access.

Next, configure your Wi-Fi network with a robust security protocol, preferably WPA2 or WPA3 if supported, and set a strong Wi-Fi password. Regularly check for and install any available firmware updates from the manufacturer, as these often contain critical security patches. Consider disabling remote management if you do not need to access your router's settings from outside your home network, as this minimizes potential attack vectors.
