My 3400c usually works fine on wireless, using the enterasys/orinoco card. Last night and this morning it couldn't connect to my router, the ip addy was set to 169.254.14.31 which was the same as the router addy. Subnet was 255.255.0.0. I've seen this dns before, it's there every time the card stops working but usually it sets itself up on rebooting.
I checked the incorrect ip on a whois through network solutions and it's some isp in Marina del Ray. Then I did a google search just using the numbers and came up with one hit on groups where someone's pc card was showing the same ip and the same subnet. The solution there, from a guy in the microsoft mvp group, was that windows m.e. assigns itself an ip in the 169.254 range when it can't get an ip from the router. From this I can gather that the wireless card I'm using does the same. Moreover, I am using win m.e. on 3 of the pcs connected to the network. Coincidence?
It's not an ISP; it's IANA, and the 169.254/16 space is reserved for "IPv4 link local" space - RFC 3330 mentions it, and its use is describe in detail at:

Short answer is you may end up with a 169.254.x.x if all else fails - link down, no DHCP server, no static settings.
Both Microsoft and Apple support it, which isn't a surprise as both have employees in the working group and that are co-authors of the draft.
