Easy way: Log in to your router (usually routerlogin.net). Look for Advanced > Administration > Firmware Update. Or use the NETGEAR Nighthawk or Orbi app.

How to fix it

  1. Do not share your Wi-Fi password with people you do not trust.
  2. Keep the router's admin password to yourself.
  3. Turn on automatic firmware updates if the router offers them, so a fix can install when NETGEAR publishes one.
  4. Read the NETGEAR notice again later for a firmware version.
