The WiFi Vulnerability gaining momentum today was to be expected as the limitations of WiFi security are a known topic. Just like DNS has its known flaws so does WiFi. WiFi encryption methods were built on WiFi security protocols such as wireless encryption protocol (WEP), WiFi protected access (WPA) and WPA2, where each encryption technique bettered its predecessor and though they contained flaws they were/are still used. 


Encryption techniques and protocols will gain more focus and the well known TCP/IP ones are likely to become secondary to the new satellite wireless efforts emerging. In the meantime, your vendor is likely to have firmware or patch updates being prepared for Krack.


The flaws of Wifi security was discussed very briefly within the paper Cryptography in 2016 - which can be downloaded from the IET Digital Library here.
