[PCTECH] Looking for an explanation

["Paul Tuohy" <tuohyp@xxxxxxxxxxxxx>]

Hi all,

I have a home network with a LinkSys Wireless-G Broadband Router. I am running 
the DHCP server on the router.

It looks like someone is trying to piggy back my network. When I check the DHCP 
Client table I see a client that isn't one of my home PCs. I don't think it is 
a neighbour coming in on wirless. If I delete it, it reappears in within the 
hour. It always has the same MAC address. It doesn't look like a live 
connection - no reply when I ping the IP address.

Is someone piggy backing onto my network through my internet connection?
Is there a rogue bit of software on one of my PCs?

I have disabled sharing on my home PCs.

All advise greatly appreciated.

TIA

Paul Tuohy
