Does it mean anything if there happens to be an unknown client that pops up in the DHCP client list but it does not get an IP address? I'm wondering because last night there was an unknown MAC address listed as an eth1 interface and did not retrieve an IP address but it did show a decent signal quality. The MAC resolved to a wireless device that I know does not exist in the house therefore I know it wasn't a family member. Does this mean someone was attempting to connect? I am still using WEP with the only reason being because my younger brother has a DS Lite.
