Well, I know it's Linksys, because the SSID says so...
And I know it's one of ours because it has our default password on it to join it's Wi-Fi LAN.
I'm guessing some group, development, sales, accounting etc. grabbed it because "it's got lots of those port-things on the back"...
The only thing is it's not DHCP'ing, nor is it running a 10.0.0.X or 192.168.1.X NAT subnet, so I can't get to it's config page. At least then I could turn it off, and see if anyone complains. Or at least see if any other MAC's are accessing it, and maybe spoof one of them if MAC filtering is on.
I'll try netstumbler and see where that gets me.
I just really want to get to it's config page, and see if it's got a WAN ip from a wall jack. That'll get me down to a floor, a side of the building, and about 50 feet of cubicles to search.
