Netgear last week pushed out a firmware update for its wireless router model NightHawk R7000 with a remote data collection feature. The company said it is collecting the data for routine diagnostic to know how its products are used and how its routers behave. If you are privacy conscious and don’t want Netgear to collect details on you, you can disable this feature. Alternatively, you could replace your device firmware with DD-WRT, a Linux-based open source firmware that is designed to enhance security and performance of wireless Internet routers.
