Wireless security

corblimey

While lazily looking at my PC contents during the week, I noticed that there were 3 PCs connected to my home network instead of the 2 I expected (and own). So tonight, I enabled WPA-PSK on my router (yes, it's dumb that I've had a wireless router for about 4 years and tonight was the night I finally turned on security). Everything seems fine, although that rogue PC is still listed in my Network. Enabling WPA should do it, right? Is there anything else I can do to make sure that my network is now secure?

Enabling WPA should do it. You may be seeing the cached ARP table entry.

you may also be seeing an active (non expired) DHCP lease.. WPA should cover you.. just as aside sometimes devices like phones and multimeda devices can connect and make it appear like you have intruder when that is not the case
