Once you get into the wireless router (using the factory reset button per CaveDweller above) there are still a couple of things you need to do to make it work reasonably well as you have described it. Plugging one home router into another will almost always cause issues because they generally use the same default network addresses. To fix this, check and see what addresses your current router is handing out (use Start->Run->type "cmd"->type "ipconfig" and look at the address you were assigned, it's probably a 192.16.1.x address). Connect to the wireless router and reset the LAN address from it's default (probably 192.168.1.1) to something else in the same subnet as your existing router but NOT the existing router's address and preferably not an address it will assign to it's DHCP clients (generally 192.168.1.2 works). Also turn off the DHCP service on the wireless router (generally a checkbox on the LAN setup). Now connect the wireless router to the wired router using one of the four LAN ports, NOT THE NORMAL WAN PORT. This allows the wireless to be bridged, rather than routed, into your local LAN (making your wireless router into what is known as a wireless Access Point). Put a piece of tape over the WAN port to remind you later not to use it. Write the new address of the router/AP, it's login password, and your newly chosen wireless passphrase (you did set one, right ?) on a strip of tape on the bottom of the unit for later reference. As you have just proven, if someone has physical access to your router all your security settings are of little use, but it's a pain if you forget them and have to reset everything every time you need to log in.
