I use WPA (TKIP) and WPA2 (AES) with a nice long passphrase. SSID is set to broadcast because it's pointless trying to hide it. Anyone with a bit of knowledge can see you lit up as soon as your AP or your clients send a few packets.
I see a couple of people use WEP or no encryption whatsoever. You must be mad! No encryption is asking for it: not only can people access your network, but you are essentially _giving_ away your personal information by broadcasting it in every direction for several hundred metres. WEP is not much better. I've cracked all my neighbours networks (7 of them) in less than a day using open software from the repos (purely a field exercise of course). It's astonishingly easy to break a WEP network and it can be done from a wide radius merely by having your router switched on - you don't necessarily have to be sending/receiving any data. You might think no-one will target you, but they will. Watch your router activity LED very carefully... http://aircrack-ng.org/doku.php?id=tutorial http://www.cdc.informatik.tu-darmstadt.de/aircrack-ptw/ http://www.kismetwireless.net/documentation.shtml Tom -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
