Anywhere Access is an efficient feature of the Netgear router that allows a user to control and access the router even when he is not at home. A user can use the Anywhere Access feature through the Nighthawk app. To efficiently utilize this feature, you must update the firmware of the router and make sure that you have kept the Nighthawk app up-to-date. You can update the firmware of the router either automatically or directly through the routerlogin.net interface.
