Well, it has a Web access like mine. If you can't access it wirelessly, hook a cable to it. If you don't know the IP address, reset it to factory defaults by holding down the reset button for 10-15 seconds then set it to a static IP. You have the default address, user and password for the default settings.
If you leave it on a static address, which needs to be outside you DHCP allowed address range, you can always find it. If you don't allow wireless access, you will have to plug in a cable when you need to change it.
If you don't have the owners manual, you can download it from the Linksys site.
