I wonder if this can be pushed out through firmware, or if you will have to purchase a whole new router?
SourceWPA3 is the latest version of Wi-Fi Protected Access (WPA), a user authentication technology for Wi-Fi connections.
News that the Wi-Fi Alliance was working on WPA3 leaked online in January. The organization started working on WPA3 after a security researcher revealed KRACK, a vulnerability in the WPA2 WiFi protocol that made it somewhat trivial for an attacker to gain access to WiFi transmissions protected by WPA2.
WPA3 is currently optional for all newly produced devices, but it will become the de-facto Wi-Fi authentication standard for all Wi-Fi capable devices in the coming years. A date has not been set yet, but the new WPA3 will retain interoperability with older WPA2 devices to ensure as less friction as possible during the transition to WPA3.
