How to control the internet access if there is a wireless device attached to supply access to another pc?

I was away for a couple of days and when I got back home there was a new laptop and a device called TP LINK(TL-WR340G) 54 M wireless router attached to my broadband modem.....Now I am not sure what to do..They changed my ip and default gateway from 192.168.1.* to 192.168.0.* and God knows what else they have done... Now I want to take my privacy and control back without blocking internet access to the new laptop( i want complete control though)...

Relax. Any network address in the range 192.168.0.0 - 192.168.255.255 is regarded as a ';private'; network according to the specification in RFC 1918. Most likely, the new router shipped with the ';0'; network instead of ';1'; and whoever set it up decided it was easier to leave it than set it to the ';old'; value (that may not be true, but it wasn't me doing the setup).





Put another way, anything your side of the router is essentially invisible to the Internet. The ';real'; IP address is on the other side, where the cable plugs into the router from the modem. Essentially, your broadband modem is the only ';real'; IP address you have, and is the only one that counts to the rest of the world.





So, sit back and enjoy. No one has done anything subversive to your computer...
Use the router's configuration page.
