Ok, funny story. I've been volunteering IT services for an environmental group in St. Louis for the past 2 weeks. One of their issues has been that their physical network sometimes goes down so they mostly depend on wireless. This is a problem because some of their desktops don't have wireless cards, also for wireless to be more reliable than Ethernet you know something's wrong. So, I connect my computer to the network and get an ip address, but i can't get out to the internet. Occasionally wireless users loose their connections also. I finally get access to the DHCP server and it seems to only be handing out ip addresses from 50-100 ... Then I watch this week's techSNAP (posted below) and suspect the same thing. A rouge dhcp server. I look at all the computers and check to see if they're doing "Connection Sharing." Then i notice the word "router" on a switch they bought before I got there. I noticed the word before but it never hit me. Also I'd actually navigated to 192.168.1.1 and gotten to the router and didn't notice that it wasn't the wireless access point/router (who's dhcp was turned off). I'd completely overlooked it in such a way because they told me it was a switch and they were using it like one. Tomorrow I'm coming in and turning off the router's dhcp server.
