Same problem with my 6500. This problem of the rig coming up in link-local while on the wired network has been very annoying. Since I've had the 6500 for a couple of years, I've had to take a different approach to using it successfully.
The FLEX should not exhibit this problem. I've changed everything in the network - it still acts the same, i.e. coming up in link-local. It does not happen all the time. It used to come up with a bad IP address 9 out of 10 boots. With newer software, it seems more like 1 link-local ip address in evert 10 boots.
Dear FLEX - any solution to this?

PS, my work-around was to connect the 6500 directly to my PC by Ethernet cable to the nic card in the PC (so it could come up with any ip address and still work). Then I connect the PC to the router via WiFi (using a USB dongle). The added benefit was to have the station equip electrically isolated form the cable system.
The Flex's symptom is that most of the time when turned it on, it would come up with a bad IP address.
