  • You should regularly reset or clear a router’s cache to avoid interruptions in the Internet connection.
  • Each router has a cache reset button, typically located on the rear of the unit.
  • This process is different from resetting a browser cache, or a DNS cache, both of which involve an address bar, command prompt, and IP addresses.
