Whenever one device on my network leaves the network router, somehow my neighbours are keeping that IP address of that device on my router and using it to get a free connection off my router. I feel really sad about this I work hard to pay my broadband bills and yet people like this can steal it so easily. What can I do to prevent this ? I have the new talk talk hub. Please can you advise me. I also think they have somehow managed to get hold of some off the routers admin details from my account area with talk talk and they have cloned a router of their own to receive data from my router.
