I have three desktops in the house plus laptops and devices. One downstairs hooked up to the TV as a media center, and two upstairs. I had my modem and router downstairs but I decided to move it upstairs the other day. As soon as I moved it, the problem began. At first I couldn't connect to the router through 192.168.2.1. So, I checked ipconfig, and found my ip address and the router's ip address not in the standard 192.168.2 format and the subnet mask was 255.255.254.0. Internet works, so I decided to check my public ip. Sure enough, what I had seen in ipconfig was my public ip. I tried resetting the router, tried a new router... nothing. The problem is that sometimes a desktop/laptop/device will have the regular 192.168.2 addresses assigned when it boots up and the internet won't work. I have to do ipconfig /release & /renew to get it to take on the funky ip addresses again and everything works fine. My not-so computer savvy family however, doesn't really want to mess with that.

"Sure enough, what I had seen in ipconfig was my public ip." This means you plugged the wan cable into the lan side of the router. Check your cabling. Imagine the power of knowing how to internet search http://www.lib.berkeley.edu/Teachin...
