Update your router/access point or operating system to fix the KRACK WiFi WPA2 vulnerability

On October 16th 2017 Mathy Vanhoef of the imec-DistriNet research group of KU Leuven published information about multiple vulnerabilities in the WPA2 protocol used for authentication in wireless networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs).

The weaknesses are in the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected. To prevent the attack, users must update affected products as soon as security updates become available. This webpage provides you links to router/access point and operating system manufacturers' websites that provide firmware updates for their products, for easy reference.
