does this mean wpa/wpa2 is totally unsafe now? or just for pre-shared key method(which is 99% home users use)?
WPA has known vulnerabilities that an attacker can use to cause a router to leak data over its WAN Ethernet port, so it should be considered unsafe at this point. But, that has nothing to do with this attack.
If you have something to hide, obviously, you should take additional precautions.
