  • Routers supplied by ISPs are less secure: Routers supplied by ISPs have hard-coded remote support credentials. And a user cannot change these details. Hence, they are less secure compared to those sold by manufacturers to consumers.
  • Keep updating the admin password: Most of the routers have a default administrator password. And hackers always try to use these publicly known credentials. So, make sure to change the default administrator password for better security.
  • Restrict which IP address can manage the router inside the LAN: It’s always good to allow access from a single IP address that is not included in the pool of IP addresses allotted to computers through DHCP (Dynamic Host Configuration Protocol).
  • Switch on HTTPS access to the router interface: If you are working with the router, always try to use the browser in incognito or private mode. This helps in wiping out session cookies and doesn’t let the browser to remember the router’s username and password.
  • Disable Wi-Fi Protected Setup: it’s recommended to simply turn off the WPS, also known as Wi-Fi Protected Setup. As an alternative, the customer can connect to the router through a wired connection and access its web-based management interface.
