NETGEAR routers are popular networking devices used to provide home and small-scale office networking solutions. These routers provide wireless and wired networking connectivity options for various devices. NETGEAR routers are highly efficient in managing network traffic, providing secure internet access, and creating multiple networks for different users and devices. Their robust feature set makes them a popular choice for consumers and small business owners who desire a reliable network infrastructure.

A critical vulnerability, CVE-2020-27866, has been detected in several NETGEAR routers, including R6020, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, JNR3210, WNR2020, Nighthawk AC2100, and Nighthawk AC2400 models.
