WPA2 has long been a good security for WiFi access points, but a security has just been reveled. This issue affects all WiFi of course. I am sure that major companies such as Google, Apple and Microsoft will be issuing patches soon. At the interim if possible you should connect your computer to your router/switch hard wired and disable WiFi. I am also hoping that router/switch makers will issue patches soon. But a vast majority of IOT will probably never get patched.
Update: WPA2 bug affects only clients and not routers. Router can be affected if its a client of another router.
