Wifi connections should probably all use WPA2, even at coffee shops if you just write the password on the wall, it defeats the purpose - everyone who logs in

if you just write the password on the wall, it defeats the purpose - everyone who logs in is on the same network again, just like a public network

- eru 16y agoEveryone being on the same network isn't too much of a problem. They still can't read each others traffic. See http://en.wikipedia.org/wiki/IEEE_802.11i-2004 http://en.wikipedia.org/wiki/IEEE_802.11i-2004 or http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#WPA2 http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#WPA2 Every device negotiates its own keys with the access point.
- hannibalhorn 16y agoVery common misconception, but it's still a problem. Any client with the network password can capture the initial key negotiation, and then decrypt the client's subsequent traffic. You can enter the network password in Wireshark: http://wiki.wireshark.org/HowToDecrypt802.11 http://wiki.wireshark.org/HowToDecrypt802.11 .
- nikcub 16y agoye I should clarify and add that it means you can see the traffic. even if it is switched
- pilif 16y agoif the AP and the gateway are separate devices, couldn't I just ARP-spoof the gateway and get all traffic on the wireless network sent over to me, regardless of encryption?
