So I was trying to do something else entirely, and was tooling AROUND inside my wireless router's settings (it's a linksys BEFW11S4 if anyone cares)...

Went to the DHCP Options tab, selected "DHCP Clients Table"... And there were like six computers there! (I have two wireless computers on my home network).

So someone is hijacking my bandwidth!

With the usual firewalls, etc., in PLACE, though, my data is safe, right? I mean, they were probably just trying to glom a free ride?

Is there an easier utility to USE to check that kind of thing out?rjbinney   Delete the four ( 4 ) that arent yours  from the
"DHCP Clients Table"...
Can you identify the ip address's of the other 4 ? If you can ,I would record them and if this keeps on happening , I would consider reporting it to your police .......they have the resources to track down these guys.

It's possible its someone who is parking inside your wireless hotspot .....and simply using your connection .

I figured it was harmless... Just want to make sure.

I went to the "restrict access" tab and put in the MAC addresses for my two laps and printer... But I know when I add another machine or have someone over, I will forget and spend hours trying to figure it out!!!

But I also enabled the logging procedures, just to see if I can figure out who it is... And then blackmail 'em!!

Some Routers have the ability to limit the braudcast area. if you made it smaller to like the size of your house then you could PREVENT people getting on and not need mac adress FILTERING on
