For a couple of reasons I'm inclined to buy a new router, most likely wireles. What I'm interested in is reclaiming/resetting my online identity. This is not about being 100 % anonymous, or 'perfect' privacy. If I get a new router my ISP will assign me a new IP based on the router's MAC address. (DHCP) So far, so good. My configuration: wireless connection from the computer to the router, the router is hooked up to my modem which is connected to my broadband/cable internet connection, no other devices in the local network. This computer is old but still good enough for basic internet access. Windows XP SP2 with updates. I can restore a clean image that only has the OS and my hardware drivers. So, if I'd get myself a new router and restore a clean image would I be able to 'reset' my online identity ? Meaning, would websites and commercial trackers be unable to associate my new IP with my old IP and the data associated with the old IP ? I wonder if the Microsoft WIN XP OS carries some unique identifier that would allow websites and commercial trackers (including Google!) to correlate my new setup with the old setup ? It doesn't have to be NSA proof ! So, the issue is not anonymity and privacy itself, but the question if they could correlate the old data with the new data, OS and browsing. Sort of, can I start from scratch ? I'm aware that profiles are created. But as long as my new browsing is not too similar to my old browsing, can I achieve my objective ? I could be very nice if I could get Google to stop offering me search results based on past searches.
