There are very simple hack tools that let others use WEP and MAC filtered networks. To solve this issue is very very simple. Enable WPA, broadcast the SSID and no MAC filters. Done.
All computers at this location access the Internet wirelessly through an 802.1g wireless router, which is cabled directly to a DSL modem. The wireless network is not encrypted, and frequently interlopers can be found camped-onto my Internet connection. Usually MAC filtering fixes this, but what I would like to do is to log traffic to and from the Internet. Can this be done from the router or by bridging the hard-wired connection between the router and the DSL modem? How difficult can this be? Thanks!
