Solution

NETGEAR strongly advises against allowing untrusted users or devices on your WiFi network. The NETGEAR C6220 has reached End-of-Support (EOS) and C6230 will reach EOS soon. Due to limited security impact (device reboots only), no fixes are planned.


Workaround

The users are advised to not allow untrusted devices to connect to the Wi-fi Network.
