The vulnerability would appear to be the targeting end point device as in the phone, tablet and likely a PC or laptop using a wireless connection. It seemingly, is not targeting the access point, IE. Router or other wireless access point. At least so far. As this quote from the link in message 5 would seem to indicate.
“Although most devices appear to be vulnerable to attacks reading Wi-Fi traffic, the exploit doesn’t target access points.”
So at least for the moment, it doesn't seem to be a router problem per se.
Perhaps if people were able utilise what would seem to be ‘best practice’ and use a wired connection for communications containing sensitive data, like Internet Banking etc. and refrain from keeping PII (personally identifiable information) on portable devices then the issue would have much less impact.
