MS-CHAPv2 is used by VPNs and can be used by RADIUS authentication services (to authenticate WIFI clients) but typically it won't be. For almost all private individuals your WPA2 connection is still just as secure as it has ever been. For most businesses it is likely secure unless you're using a Microsoft RADIUS server for authentication (and even then as the article says the impact is almost nil). Which isn't to say that the MS-CHAPv2 thing isn't a big deal: because it really is. It just doesn't have much to do with WIFI.
