A new icon I have never seen before for a PC connection to my wireless LAN has alerted me that someone the area is attempting to connect. The icon only indicates that it is a PC. No IP or any info like that. What I am after is intrusion detection software for a wireless LAN. * how can I get the IPs of the connected or trying to connect? * can I "snort out" those trying to break in with WEP cracks?
Lots of replies to this - mac filtering, WPA2, limited ip range, etc. Whilst mac filtering and a limited ip range are passable, security is usually a layered approach, so use them in combination.
Also, keep in mind that upgrading the firmware on your wireless router may give you new features (like ips of those trying to connect, or showing the DHCP lease table). In addition some products eg WRT54G have open source replacement firmware that give you tonnes of additional features that may help you here.
