I say share the love, it's not like you get charged by the megabyte.

I wonder what you will say when they charge you from uploading illegal stuff for wikileaks. Its not a good idea to have open wifi connection.

I dont know what type of router are you using, but be sure thet its not any adress a router is using and after that ban him in mac list. One time i saw something similar, banned and it was some adress my router was using (i always see IP of computers + IP of router). I ended up reseting it :)

Share the love but only with people you trust. Its you who is responsible for activity on your internet connection.

Could be an internet connected device such as a plugport, or something like that.

Most likely you are using WEP, and one of your neighbors has cracked your password--it is quite trivial to break WEP encryption.

Per the address, you can manually set your address to anything you want, some routers will ignore clients that don't have an address in the right range (some even ignore any clients that didn't get an address assigned to it from the router), but many will happily route traffic to any address you want, you just need to set your subnet mask correctly to allow it.

That said, it is truly sad, but in this day and age where you are personally liable for anything that is downloaded from your modem it not safe to have an access point open, or even encrypted with WEP. One would hope it is just someone who wanted to check their e-mail, but it could also be someone downloading illegal warez looking for an unsuspecting family to take the blame instead of himself/his parents.

ha ,but it's easy:I don't know who did this ,I have an open connection.
plus the chance that some one upload to wikileak using your connection is ridiculously small,unless you leave next to a Diplomatic house...

people do have caps on home internet now, so boot him! AT&T (/SBC Global etc) bow have a 100GB cap for DSL and 250GB for U-Verse, they didn't even try to really tell us I just keep up with such things by chance!

But anyways, yeah change the keys, and KEEP THE LOGS! If the person was doing something illegal keep the evidence of it.

just my 2c, Jimmy

00:1D:E0 MAC prefix is an Intel Network card

Some users machines/cellphones may simply auto-connect to any open network.

MAC spoofing is less common, but even WPA2 PSK can't stop offline busting of a weak password.

Or if you are interested in forensics... solve the problem...

kismet + GPS + Trilateration (ARRL adaptive attenuators are easy to build)
Link2
Link2

...but this forum is not really keen on these kinds of nuisances...

Try:
* WPA2
* PSK (a really long random string)
* lower your router's transmit power to just above signal loss
* turn off cross forwarding LAN traffic for wireless interfaces

Cheers,
Rod
